...B. Chudnovsky; A. Talanker; Y. Berman; R. Saveliev; M. Perelman; E. Korytnyi; B. Davidson; E. Bar-Ziv The present regulatory requirements enforce the modification of the firing modes of existing coal-fired utility boilers and the use of coals different from those originally designed...

...Gang Xu; HongGuang Jin; YongPing Yang; Liqiang Duan; Wei Han; Lin Gao In this paper, we have proposed a novel coal-based hydrogen production system with low CO 2 emission. In this novel system, a pressure swing adsorption H 2 production process and a CO 2 cryogenic capture process are well...

... of the effect of syngas on the LSI flame behavior, the emissions, and the flowfield characteristics for adaptation to the combustion turbines in integrated gasification combined cycle clean coal power plants. The experiments were conducted in two facilities. Open atmospheric laboratory flames generated...

...Hongguang Jin; Shien Sun; Wei Han; Lin Gao This paper proposes a novel multifunctional energy system (MES), which cogenerates coke, hydrogen, and power, through the use of coal and coke oven gas (COG). In this system, a new type of coke oven, firing coal instead of COG as heating resource...

...E. A. Harvego; M. G. McKellar; J. E. O’Brien A system analysis has been performed to assess the efficiency and carbon utilization of a nuclear-assisted coal gasification process. The nuclear reactor is a high-temperature helium-cooled reactor that is used primarily to provide power for hydrogen...

...Luca De Lorenzo; Thomas G. Kreutz; Paolo Chiesa; Robert H. Williams Conversion of coal to carbon-free energy carriers, H 2 and electricity, with C O 2 capture and storage may have the potential to satisfy at a comparatively low cost much of the energy requirements in a carbon-constrained world...

...Xun Wang; Yunhan Xiao; Song Xu; Zhigang Guo A co-production system based on Fischer-Tropsch (FT) synthesis reactor and gas turbine was simulated and analyzed. Syngas from entrained bed coal gasification was used as feedstock of the low-temperature slurry phase Fischer-Tropsch reactor. Raw synthetic...

...Hongguang Jin; Wei Han; Lin Gao A new kind of multifunctional energy system (MES) with multifossil fuels and multiproducts is proposed in this paper. This new system consumes coal and natural gas as fuel simultaneously, and cogenerates methanol and power. Coal and natural gas are utilized...

...Linda G. Blevins; Thomas H. Cauley, III Experiments to examine the effects of biomass/coal cofiring on fine particle formation were performed in the Sandia Multi-Fuel Combustor using fuels of pure coal, three combinations of switchgrass and coal, and pure switchgrass. For this work, fine particles...

... or premixed flames in the regenerative high-temperature air combustion facility have been examined using coal gas as the fuel. The fuel gas composition consisted of H 2 , hydrocarbon, CO, and N 2 . Monochromatic images of the flames have been observed in the emission mode using a CCD camera fitted...

... the design coal. A comprehensive test program was undertaken to monitor the performance of the boiler. Predicted performance from both the manual design and the Expert System is compared with those measured in the boiler. A reasonable agreement between the predicted performance and measured values...
