Under the sponsorship of the U.S. Department of Energy/National Energy Technology Laboratory, a multidisciplinary team led by the United Technologies Research Center (UTRC) has identified a high performance biomass gasification/combined cycle system using Refuse Derived Fuel (RDF) as the major fuel resource. The system consists of fuel receiving/preparation/feed, advanced transport gasifier, high temperature gas cleanup and Pratt & Whitney Power Systems FT8 aero-derivative gas turbine with heat recovery steam generator and steam turbine. One of the team members, Connecticut Resource Recovery Agency (CRRA), currently processes approximately 2200 tons/day of municipal solid waste and delivers 1825 tons/day of RDF “across the fence” to a nominal 65 MWe steam plant. Based on the characteristics of the RDF from this plant, an 80 MWe combined cycle system having an estimated efficiency of 45% (RDF in/kW out) was identified. Other advanced cycle variations had even greater performance potential. The resulting cost of electricity for the biomass integrated gasification combined cycle (BIGCC) is competitive with that of natural gas fueled combined cycles, and the plant is projected to meet or exceed all environmental requirements.

In this paper the coal-fired power plant with CO2 capture by integrating MCFCs system and the integrated coal gasification with CO2 capture by integrating MCFCs combined cycle system are compared with each other in different ways. The effects of the key parameters of MCFC on the performance of two systems, such as CO2 utilization factor, fuel utilization factor and the current density of MCFC, have been analyzed and compared. Aspen Plus soft is used to develop the system models and the key parameters of MCFC are calculated, analyzed and optimized. The flue gas of the coal-fired power plant (CFPP) or the Integrated Gasification Combined Cycle (IGCC) system is used as the reactant gas of MCFC cathode side, reacting with fuel in the anode side and producing power. The anode exhaust gas burns with pure oxygen in the afterburner. The CO2 in the flue gas is further concentrated and captured with the lower energy consumption. The results show that, the efficiency of the coal-fired power plant integrating MCFCs system is about 45.75% when the CO2 capture rate is 88.07%, and the efficiency of the IGCC system integrating MCFCs is about 47.31% when the CO2 capture rate is 88.14%. Achievements in this paper will provide the valuable reference for CO2 capture of coal-fired power plant and IGCC with low energy penalty.

This paper studies an Integrated Gasification Combined Cycle-Solid Oxide Fuel Cell (IGCC-SOFC) hybrid power system. Based on the intercrossing of electrochemical process and thermodynamic cycle, this paper has proposed a dual cycle IGCC-SOFC hybrid power system. Based on the Aspen Plus soft, the model of the IGCC-SOFC hybrid power system has been established and the performance of the overall hybrid power system affected by the main operating parameters of SOFC system has been analyzed and optimized. The obtained results show that IGCC system integrated with the high temperature SOFC combined cycle system has a higher thermal efficiency through decreasing the current density; the higher fuel utilization ratio (ηg) also improves the efficiency of hybrid power system; with the increase of the syngas distribution ratio Xfl, both the total power output and system efficiency of the hybrid power system are improved greatly. When Xfl is 1.0, compared with the base IGCC system without integration with SOFC system, the efficiency of hybrid power system increases by 10 percentage points approximately. Above research achievements will provide a valuable guide for further study on IGCC-SOFC hybrid power system.
