Title: Fuel-Adaptability Analysis of a Solid Oxide Fuel Cell and Gas Turbine(SOFC/GT) Hybrid System using Gasified Biomass Fuel and Its Application in Low-Carbon Energy System
Abstract: 
Solid Oxide Fuel Cell and Gas Turbine (SOFC/GT) hybrid systems are thought to be the most attractive energy conversion systems in future energy markets because of high efficiency (>70%), low pollution, and fuel flexibility (such as natural gas, biomass gas, methanol, diesel). The systems are suitable for mobile applications and distributed power generation because they can function in a standalone manner to provide power. Biomass is rich and important renewable energy and it has the characteristics of low net CO2 emission rate and SO2 emission rate. For this reason, the author uses the mathematical model of SOFC/GT to study the effects of gasified biomass fuels on system load characteristics. The system performance is investigated by using four types of fuels in each adjusting mode. The safe operating characteristics of the system at all operations are analyzed. Six safe factors, such as compressor surge and choke, turbine inlet temperature, fuel cell working temperature, etc. are considered to determine the safe characteristics. The relation between the fuel type and load adjusting mode is obtained for users and designers to select the appropriate fuel for reasonable operation modes. Results show that the hybrid system of 182.4 kW has a high electric efficiency of 60.78% by using wood chip gas (WCG). If cotton wood gas (CWG) and corn stalk gas (CSG) are used, both boundary values of steam to carbon ratio (S/Cbv) and system power are higher, but system efficiencies decrease to 57.36% and 57.87% respectively. Finally, according to the technical characteristics of hybrid system, the application prospect of SOFC/GT in the field of low carbon energy system is presented.
