Technical Analysis Of Biomass Gasification Fuelled Hybrid Sofc System Congfigurations For Thailand Rice Husk
The study deals with the design and analysis of plant design configurations of integrated biomass gasification fuelled solid oxide fuel cell (SOFC) for combined heat and power (CHP) applications. In this study, biomass gasification fuelled SOFC-Gas turbine with HRSG hybrid configuration (case 1) is compared with biomass gasification fuelled SOFC-Steam turbine cycle (case2). Three types of gasifiers air blown, mixed air-steam blown and steam blown alone coupled to the hybrid cycles are compared to know the system electrical efficiency and heat integration area at various SOFC pressures and hydrogen utilization factors. In air gasification mode, the system electrical efficiency reached up to 23 % for both case 1 and case 2. In case of steam gasification mode, the case 1 showed the electrical efficiency upto 63 % which is highest as compared to all the case designs. In case of mixed air-steam gasification mode, electrical efficiencies were in the range of 34 % to 20 % and 35 to 17 % for case 1, case 2 repectively.The case 2 under brayton cycle mode prove to be technically feasible in terms of system electrical efficiency. The heat exchanger surface area required for case 2 prove to be minimum as compared to mixed air-steam and steam gasification mode. The results are very useful for further economic viability of CHP schemes for pilot research studies.
