PARAMETRIC ANALYSIS ON HYBRID SYSTEM OF SOLID OXIDE FUEL CELL AND MICRO GAS TURBINE WITH CO_2 CAPTURE

摘要

Three hybrid systems of solid oxide fuel cell-micro gas turbine are designed and simulated based on the IPSEPro simulation platform. The results show that Case 2 is a better one, whose system efficiency is 59% and CO_2 capture rate is 99%. Case 2 is suitable to build quasi-zero carbon emission plant, and Case 3 is suitable to reformation of existing plant. Then the effect of capture rate on system performance of Case 2 and Case 3 is investigated. The suggested capture rate for Case 2 and Case 3 is given based on the result, taking both economic and carbon emission into consideration.
