Title
:Coal Chemical-Looping Combustion for Electricity Generation: Investigation for a 250 MWe Power Plant
Author
:Authier, Olivier; Le Moullec, Yann;

Abstract :

Chemical-looping combustion (CLC) is generally based on interconnected fluidized beds where a solid oxygen carrier provides the oxygen for combustion in a fuel reactor (FR). The reduced oxygen carrier is then regenerated to oxidized state in an air reactor (AR) before being recycled to FR to complete the loop. CLC may be suitable and highly promising for power plants with near-zero CO2 emissions. This paper presents, from process thermodynamic modelling, a theoretical investigation of coal chemical-looping combustion for electricity generation with usual steam cycle. The technical issue of unburned compounds minimization at FR outlet is examined through direct oxygen injection in FR. Heat recovery systems are combined on the one hand with a supercritical seam cycle suited to low corrosivity of depleted air from AR, and on the other hand with a sub-critical steam cycle used in open-loop for steam production to fluidize oxygen carrier in FR and gasify char obtained from coal pyrolysis Read more..

:Fluidised bed oxy-fuel gasification of coal: Interactions between volatiles and char at varying pressures and fuel feed rates
Author
:Xiangyi Long; Nicolas Spiegl; Millan, Marcos;

Abstract :

Fluidised bed gasification is a versatile technology in terms of load flexibility and ability to process various fuels. However, fluidised bed gasification processes are usually air-blown, making integration with CO2 capture difficult and expensive. Operation of a fluidised bed gasifier with O2/recycled CO2 mixtures has been proposed as a route to overcome this drawback. In this work, the effect of pressure and fuel feed rate on the extent of gasification of German lignite in a CO2 rich atmosphere has been examined in a fluidised bed reactor (FBR). A 19% decrease in carbon conversion with increasing pressure from 5 to 20 bara was observed. The higher fuel feeding rates needed to maintain the gasification agent to coal ratio in the FBR at high pressures produces a larger concentration of tars in the reactor, which seems to cause deposition, by intra and inter particle reaction, on the char and reduces its reactivity.

:Co-Firing of Oil Palm Empty Fruit Bunch and Kernel Shell in a Fluidized-Bed Combustor: Optimization of Operating Variables
Author
:Priatna Suheri; Vladimir I. Kuprianov;

Abstract :

Palm kernel shell and empty fruit bunch (as secondary fuel) were co-fired in a fluidized-bed combustor using alumina sand as bed material to prevent bed agglomeration. During the experiments, the fuels were injected into the reactor at different levels ensuring constant heat input, while the energy fraction of secondary fuel (EF2) was ranged from 0 to 0.25 with excess air (EA) of 20–80%. The study revealed significant effects of EF2 and EA on the CO, CxHy, and NO emissions, as well as on the combustion efficiency of the combustor. Cost-based optimization aimed at minimizing “external” costs of the biomass–biomass co-combustion was applied to determine the optimal values of EF2 and EA. Under optimal operating conditions, the combustor can be operated with high (about 99%) combustion efficiency at minimum emission costs, while reducing the NO emission roughly by 35% compared to firing pure palm kernel shell.

Author
:Helbig, Martin; Hilz, Jochen; Haaf, Martin;

Abstract :

Abstract | Full Text The carbonate looping process is an efficient carbon capture technology to reduce the amount of carbon dioxide emitted by fossil fueled power and industrial plants. The presented work discusses the results gained in four test campaigns, each four weeks long, performed in a 1 MWth carbonate looping pilot plant at Technische Universität Darmstadt. The flue gas was provided by a coal fired furnace. The calciner was fired in a recirculated oxy-fuel combustion mode, i.e. where coal was burned with oxygen and flue gas was recirculated to moderate the temperature. The objective of these test campaigns with optimized configuration was to improve and to scale up the process into an industrial size. During the campaigns, the type of fuel, sorbent, flue gas composition, reactor design, and operating conditions were varied to investigate long-term effects on the pe Read more..

Author
:Guo, P; Saw, W; Eyk, P. van;

Abstract :

A coal to liquid (CTL) polygeneration process with a solar hybrid dual fluidized bed (SDFB) gasifier (SCTL) is investigated in recently processing paper. A storage unit was integrated to store sensible heat in bed material in order to reduce the influence of solar resource transience. In this paper, a Fischer-Tropsch liquid fuel production system via solar hybrid co-gasification of coal and biomass in SDFB gasifier (SCBTL) is investigated. The energetic and environmental performanceof the SCBTL system is assessed as a function of the biomass ratio and char conversion. It is found that the performance of the SCBTL system is found to be less sensitive to char conversion in the gasification reactor (Xchar,g) than the SCTL system.As theXchar,g decreases from 100% to 57%, the annually averaged solar share of the SCTL system is reduced from 24% to 0, while the solar share of the SCBTL system with wood fraction (higher heating value basis) of 0.5 and 1only decreases to 7% and 13% respectiv Read more..

Title
:Chemical Looping for Pre-combustion and Post-combustion CO2 Capture
Author
:C, Hari; Mantripragada; Rubin, Edward S.;

Abstract :

In the paper, performance models are developed for two CO2 capture technologies – (a) a chemical looping combustion (CLC) process for pre-combustion CO2 capture from the syngas of a coal-based integrated gasification combined cycle (IGCC) power plant; and (b) a CaL cycle for post-combustion CO2 capture from a pulverized coal (PC) power plant –and used to conduct detailed thermodynamic analyses of IGCC and PC power plants with the respective chemical looping-based CO2 capture processes. Results from the performance models are used to estimate the capital cost ($/kW) and operating cost ($/MWh) of each capture process as well as the complete power plant. Results of the case studies using the techno-economic model indicate that, in terms of performance, both of the chemical looping technologies modelled here are thermodynamically much better than conventional CO2 capture technologies, resulting in lower overall plant energy penalties. However, both the technologies are found Read more..

Title
:Co-firing of coal and rice straw pellet in a circulating fluidized-bed reactor
Author
:Unchaisri, Thanet; Suneerat Fukuda;

Abstract :

This paper presents the experimental investigation of co-firing of coal with rice straw pellet in terms of combustion efficiency, gaseous emissions (CO, NOx and SO2) and occurrence of bed agglomeration. The influence of excess air ratio (EA) and mass share of rice straw in the mixed fuel were investigated in a lab-scale circulating fluidized bed (CFB) reactor. The fuel feed rate was fixed at 14 kg/hr, while the air supply was varied to achieve EA 1.28-1.94. Rice straw pellet was mixed with coal at 25% and 50% mass fraction. The results show that increasing EA generally reduced CO emission. However, at excessively high EA, CO emission started to rise due to the insufficient residence time for complete combustion and the cooling effect. The CO emission clearly reflected the combustion efficiency trend. Higher CO emission was also found when increasing biomass, which may be influenced by the lower combustion temperature and the incomplete combustion of biomass volatiles. NOx and SO2 em Read more..

Title
:Repowering Options for Complying with Canadian CO2 Emission Intensity Limits on Existing Coal Plants
Author
:Butler, David; Hume, Scott; Scott, Stephen;

Abstract :

The Canadian federal government has introduced carbon dioxide emission intensity limits of no greater than 420 kg/MWh net for new coal plants and existing coal plants more than 50 years of age. Many operating coal plants in Canada will be impacted by this legislation in the near future, requiring operators to plan a compliance strategy. The Canadian Clean Power Coalition (CCPC) investigated the performance and economics of a number of options for existing plants that could deliver compliant solutions. These options included strategies in which natural gas is available and some in which only coal firing is feasible due to cost or logistical issues. Repowering and post-combustion capture (PCC) options were studied using an eastern Canadian power plant firing bituminous coal. The base-case (BC) option was a new combined-cycle gas turbine (CCGT) plant, against which all other options were compared. The following cases were investigated: 1) PCC using: a) Monoethanolamine MEA solvent with Read more..

Title
:Post-combustion CO2 capture from a natural gas combined cycle power plant using activated carbon adsorption
Author
:Jiang, L; Gonzalez-Diaz, A; Ling-Chin, J;

Abstract :

As fossil fuel power plants have emitted significant quantity of carbon dioxide (CO2) into the atmosphere which aggravates climate change, capturing and storing such emissions is key to mitigate the issue. An adsorption system based on a physical adsorbent i.e. activated carbon is first assessed to capture CO2 emissions from a natural gas combined cycle. Then a subcritical sequential supplementary firing combined cycle with CO2 capture is used to analyse the effect of CO2 concentration. Analyses are carried out in terms of power loss and thermal efficiency. To evaluate the advantages of post-combustion CO2 capture using activated carbon, results are compared with systems using a commercial absorbent, i.e. monoethanolamine and a chemical adsorbent i.e. polyethyleneimine/silica. The net efficiency of natural gas combined cycle using activated carbon increases slightly from 50.8% to 51.1% due to the lower regeneration temperature at 358 K. The performance of the system using PEI/ Read more..

:Optimization of Stage Numbers in a Multistage Fluidized Bed Temperature Swing Adsorption System for CO2 Capture
Author
:Pirklbauer, Julius; Hofbaue, Hermann;

Abstract :

A dual loop multi stage fluidized bed process for continuous temperature swing adsorption (TSA) of CO2 is investigated using a thermodynamic process model. The operating case is chosen in accordance with a typical post-combustion CO2 capture process, i.e. 90% CO2 capture rate from a gas stream with 10 vol% CO2 content. Steam is used as the stripping agent on the desorber side. Adsorption thermodynamic data for an amine functionalized sorbent material are employed based on adsorption isotherm data from the literature using the Langmuir model. The optimum stage number on both adsorber and desorber side are investigated with respect to achieve high energy efficiency of the separation process. This means that a low stripping steam demand and a low solids circulation rate are desired. The results show that both solids circulation rate and stripping steam demand are low for configurations with multiple stages for both the adsorber and the desorber. The effect of additional stages is high Read more..

:Distribution of rare earth elements in coal combustion fly ash, determined by SHRIMP-RG ion microprobe
Author
:Kolker, Allan.; Scott,Clint; Hower, James C.;

Abstract :

During coal combustion for electric power generation, rare earth elements (REE) are strongly retained in the ash fraction leading to significant enrichment compared to the REE content of the respective feed coals. Knowing how the REE are distributed in coal ash is essential to devising effective approaches for REE extraction from this potential resource. To better understand the distribution of REE in coal ash, we used the Stanford-USGS SHRIMP-RG ion microprobe to determine grain-scale REE partitioning in a suite of 19 U.S. and international coal fly ash samples. SHRIMP-RG microanalysis used a nominal spot size of 15μm and an oxygen negative-ion primary beam. NIST multi-element glass standards SRM 611 and SRM 613 were used for REE calibration. Prior to SHRIMP-RG analysis, samples were characterized by backscattered electron imaging and wavelength-dispersive elemental mapping to delineate constituents of interest for REE microanalysis. Results confirm the occurrence of REE in alum Read more..

Abstract :

Coal is the dominant energy source in China, and coal-fired power accounts for about half of coal consumption. However, air pollutant emissions from coal-fired power plants cause severe ecological and environmental problems. This paper focuses on near-zero emission technologies and applications for clean coal-fired power. The long-term operation states of near-zero emission units were evaluated, and synergistic and special mercury (Hg) control technologies were researched. The results show that the principle technical route of near-zero emission, which was applied to 101 of China’s coal-fired units, has good adaptability to coal properties. The emission concentrations of particulate matter (PM), SO2, and NOx were below the emission limits of gas-fired power plants and the compliance rates of the hourly average emission concentrations reaching near-zero emission in long-term operation exceeded 99%. With the application of near-zero emission technologies, the generating costs in Read more..

Abstract :

To protect the environment changing, coal combustion must reduce its CO2 emission by capture and storage. Chemical looping is a potentially high technology for coal combustion with CO2 capture efficiently. A chemical-looping-combustion system, using circulating fluidized bed witch consist two main reactors, a fuel reactor and an air reactor. An oxygen carrier, typically a metal oxide, is employed to transfer oxygen from the air reactor to the fuel reactor, and circulates between these two reactors. During 2012-2014, JCOAL, MHPS (Mitsubishi Hitachi Power Systems (2012-2013 Babcock-Hitachi)) and IAE(The Institute of Applied Energy) have a project funded by NEDO (New Energy and Industrial Technology Development Organization) to surveyed chemical looping technology development in the world, studied market needs of chemical looping combustion, investigated carrier costs and reactivity, etc., in order to reduce CO2 separation recovery cost to 2,500 yen/ton of CO2 or less.

:Solid Waste Mixtures Combustion in a Circulating Fluidized Bed
Author
:Hanfei Zhang; Caixia Lv;

Abstract :

To efficiently and environment friendly combust the domestic garbage, sludge, and swill waste fuels, five different fuels are prepared by mixing the waste fuels together with coal, and grass biomass at different mixing ratios, and finally those fuels were combusted in a circulating fluidized bed (CFB) reactor. The emission performances of NOx, dioxin, and heavy metal during the combustion tests are studied. The results showed that a stable furnace temperature can be reached at approximately 850 °C when combusting all studied mixed fuels, benefiting the thermal processes of sludge and domestic garbage and thus realizing the purpose of waste-to-fuel. In addition, the dioxin emissions are much lower than the emission standards, and NOx emissions could be reduced significantly by adjusting the ratio of waste fuels. However, the emissions of mercury, lead, and the combinations of chromium, tin, antimony, cupper and manganese components all exceeded the pollution control standard for Read more..

Abstract :

In this study, first of its kind complete plant scale integration of pre-combustion CO2 capture method with Chemical Looping Reforming (CLR) of Natural Gas (NG), Water Gas Shift (WGS) process, CO2 capture and CO2 compression in a combined cycle power plant has been presented. The CLR consisted of oxidation and fuel reactor. The oxidation reactor oxidizes the metal oxygen carrier with compressed air and produces an oxygen depleted air stream (N2 stream) as by-product. The fuel reactor reforms the NG with the metal oxide in presence of steam to produce syngas. The syngas is further subjected to WGS and CO2 capture using a-MDEA, to prepare a H2-rich fuel, which is combusted in the Gas Turbine (GT) system. The heat from cooling of process streams in the pre-combustion CO2 capture method, is used to prepare saturated low pressure steam, fraction of which is used in reboiler to regenerate the amine for CO2 capture, and the remainder is expanded in Steam Turbine (ST) to generate power.

:Comparative Evaluation of the Performance of Coal Combustion in 0.5 and 50 kWth Chemical Looping Combustion Units with Ilmenite, Redmud or Iron Ore as Oxygen Carrier
Author
:Abad, A.; Mendiara, T.; Gayan, P.;

Abstract :

Chemical Looping Combustion (CLC) is one of the most promising technologies to achieve the CO2 capture at a low economic and energetic penalty. In CLC the combustion is split in two steps: fuel combustion assisted by an oxygen carrier in the fuel reactor, and oxygen carrier regeneration in the air reactor by oxygen in air. Usually, the air and fuel reactors are interconnected fluidized beds, with the oxygen carrier circulating between them. Thus, the CO2 capture is inherent to the CLC process. The use of solid fuels in CLC is attracting great attention due to coal is the most abundant fuel, and burning biomass with CO2 capture would allow to reduce the atmospheric CO2 concentration. The in situ Gasification CLC (iG-CLC) allows the conversion of the solid fuel by performing both gasification and combustion of gasification products in the fuel reactor. In iG-CLC complete combustion is not reached, and an oxygen polishing step is required downstream by using a small fraction of pure ox Read more..

Author
:Ya Lan Ye; Hong Ming Wang; Xiang An;

Abstract :

For coal and gas dual-fired boiler, pulverized coal mass flow and gas volume flow into furnace are important criteria for boiler operation adjustment, and they are important input parameters for boiler performance analysis. However, different from the gas volume flow measurement technique that is mature, the measurement of pulverized coal mass flow is difficult, especially for the boiler equipped with middle storage pulverizing system. In order to solve this problem, an indirect measurement method through other operation parameters was put forward to obtain the pulverized coal mass flow. Its solving idea is to calculate the coal combustion and the gas combustion, in order to get the flue gas products corresponding to unit mass of coal and unit volume of gas respectively, and then obtain the pulverized coal mass flow by the flue gas products and the gas volume flow. This method solves the long-standing difficulty for pulverized coal mass flow, and has certain practical value. Read more..

Author
:Lara, Yolanda; Romeo, Luis M.;

Abstract :

The share of renewable energy production is growing quickly. The output and variability of renewable power will force to fossil fuel power plants to adapt its electricity production to variable demand. In a future scenario, with CO2 capture systems installed in power plants, the variable performance will affect not only to fossil fuel power plant but also to the CO2 capture behavior. The knowledge of part load performance of fossil fuel power plants with CO2 capture systems will be essential in a near future. This paper analyzes the integration between Ca-looping cycles and power plants to foresee the requirements derived from a flexible operation. With this goal, the performance of the integrated system under different load scenarios is studied. An integration scheme designed for nominal load is proposed under different load scenarios at steady state, to study their performance. Then, for each load scenario, the optimum integration is designed, to quantify the minimum energy penalt Read more..

Author
:Zaabout, Abdelghafour; Romano, Matteo C.; Cloete, Schalk;

Abstract :

The SARC consists of a number of standalone reactors where a solid sorbent is carbonated by a flue gas and regenerated by a combination of vacuum and temperature swing. Efficiency is maximized through heat integration between carbonation and regeneration using a heat pump. Initial power plant simulations showed 9.4%-points energy penalty when integrated into a pulverized coal plant. This is in-line with reported energy penalty for MEA and VPSA technologies, but great potential for further efficiency improvements exists. Future studies will investigate the effect of SARC process parameters and sorbent material selection on the energy penalty. Read more..

Author
:Md Rezwanul Karim; Jamal Naser.;

Abstract :

Biomass is a renewable energy which has become an important fuel to produce thermal energy or electricity. It has no adverse effect on environment as it reduces carbon dioxide emissions. Biomass combustion is a difficult phenomenon due to its properties with less carbon, more volatile matters and lower calorific value. Fixed bed combustion is a useful technique for thermal conversion of solid biomass fuels as this can fire up a broad range of fuels with different properties and requires less fuel preparation. But due to complex solid combustion mechanism and inadequate knowledge on process the development of such combustion system is limited. Numerical modelling of this combustion system has some advantages over experimental analysis. But developing a complete model for this type of combustion system is a challenge. Due to its characteristic properties, modelling of biomass combustion has to overcome many difficulties. One such problem is initiating the combustion in numerical model Read more..

Abstract :

THIS BOOK is the fully revised and updated second edition of "Consciousness and Robot Sentience". With lots of new material, it will provide new insights into artificial intelligence (AI) and machine consciousness, beyond materials published in the first edition. The organization of this book has been streamlined for better clarity and continuity of the lines of arguments. The perspective of AI has been added to this edition. It is shown that contemporary AI has a hidden problem, which prevents it from becoming a true intelligent agent. A self-evident solution to this problem is given in this book. This solution is surprisingly connected with the concepts of qualia, the mind-body problem and consciousness. These are the hard problems of consciousness that so far have been without viable solution. Unfortunately, the solution to the hidden problem of AI cannot be satisfactorily implemented, unless the phenomena of qualia and consciousness are first understood. In this Read more..

Abstract :

This book focuses on a class of uncertain systems that are called imperfect, and shows how much systems can regularly work if an appropriate control strategy is adopted. Along with some practical well studied examples, a formalization of the models for imperfect system is considered and a control strategy is proposed. Experimental case studies on electromechanical systems are also included. New concepts, experimental innovative circuits and laboratory details allow the reader to implement at low cost the outlined strategy. Emergent topics in nonlinear device realization are emphasized with the aim to allow researchers and students to perform experiments with large scale electromechanical systems. Moreover, the possibility of using imperfections and noise to generate nonlinear strange behavior is discussed. Read more..

Sensors for measuring and detecting chemical and biological substances are comprehensively used and are, for the most part, unobtrusive. They can help monitor our health through alerting us to chemical or biological changes in our bodies, our environment through checking air quality or pollution levels and they can contribute towards a more sustainable future. Polymer-based sensors are the subject of much attention due to their ability to collect molecules on their flexible sensory surfaces. However, most petroleum-based polymers are not renewable, leading to problems of waste-disposal. By using renewable materials, such as paper, cotton or starch, these problems can be overcome. This book reviews the current state-of-play in renewable-material-based chemical sensors and biosensors, and suggests applications in industry, environment and biomedicine. Read more..
