Thermodynamic Analysis of SOFC/GT/KCS Integrated Power Generation System With Reheater of Concentrated Ammonia Vapor
摘要
Abstract
ABSTRACT:A newsolid oxide fuel cell/gas turbine/ Kalina cycle system (SOFC/GT/KCS) integrated power generation system was proposed. The new system was simulated by using the EES software based on the developed mathematical models, and the system performance was evaluated by the first and second laws of thermodynamics.The parametric study was also conducted to investigate the influenceof the main parameters, such as the flowrate, thefuel utilization factor, thecompressor pressure ratio and the steam-to-carbon ratio on the system performance in detail. The results indicate thattheSOFC electrical, the system overall electricaland the exergy efficiencies reach about 49.2%,67.6% and68.16%, respectively, underthe ratedconditions. It is also found that the largest exergy loss occurs in the waste heat boiler followed by the SOFC, the gas turbine, the HR3, and the after-burner in the system. In addition,there is an optimalfuel utilizationfactor (0.85)to reachthe maximum overall electrical, exergy and the SOFC electrical efficiencies. And the overall electrical and exergy efficiencies can be improved by decreasing the air flow rate, fuel flow rate, andthe steam-to-carbon ratio within the range of parameters studied.关键词
