This paper presents the technologic characteristics and economics of 4MWe biomass integrated gasification (gas engine/steam turbine) combined cycles (BIG/CC) demonstration power plant, which is being under construction in China. It features a biomass fuel pretreating and feeding unit, a 1.5MWth CFB biomass gasifier, a gas cleanup unit, an internal combustion gas engine (ICGE) cycle producing 2.5MW electricity and a steam turbine cycle producing 1.5MW electricity. Comparing with the ICGEs single cycle systems, this technology route not only increases the overall energy efficiency of the power plant but also reduces the technological risks. A detailed cost model is developed for the present technology. Estimated cost of electricity suggests that 8MWe scale BIG/CC power plant can obtain good scale economy in China.
