Modeling and Process Analysis of a Biomass Gasifier-Molten Carbonate Fuel Cell-Gas Turbine-Steam Turbine Cycle as a Green Hybrid Power Generator

Fuel cell-based hybrid cycles that include conventional power generators have been created to modify energy performance and output power. In the present paper, integrated biomass gasification (IBG)-molten carbonate fuel cell (MCFC)-gas turbine (GT) and steam turbine (ST) combined power cycle is introduced as an innovative technique in terms of sustainable energy. In addition, biomass gasificati...

Measurement of Natural Radioactivity in Coal, Soil and Water Samples Collected from Barapukuria Coal Mine in Dinajpur District of Bangladesh

The activity concentrations of naturally occurring radionuclides Ra-226, Th-232 and K-40, were measured by using a gamma ray spectrometry for coal, soil and water samples collected from the Barapukuria coal mine in Dinajpur district of Bangladesh. The average activity concentrations of Ra-226, Th-232 and K-40 in coal samples were found to be 6.21±3.68, 10.69±7.5 and 185.76±138.86 Bqkg, respecti...

The purpose of this study is investigating the chemical analysis of drinking water in Kashan district. This district contained Kashan, Aran and Bidgol and Nooshabad cities and it had an estimated population more than of 400,000 in 2007. 42 Samples were collected during October 2006 to May 2007.The temperature of the water Samples is in the range 25-30°C. The water samples were analyzed for pH ,...

Shell Gasifier-based Coal Igcc with Co2 Capture: Partial Water Quench vs. Novel Water-gas Shift

We provide a detailed thermodynamic and economic analysis of two novel alternatives to the “standard” Shell coal IGCC with CO2 capture. In the first, the syngas coolers are replaced by a “partial water quench” where the raw syngas stream is cooled and humidified via direct injection of hot water. This design is less costly, but also less efficient. The second approach retains syngas coolers but...
