Investigating the Integration of a Solid Oxide Fuel Cell and a Gas Turbine System with Coal Gasification Technologies

Abstract

Solid oxide fuel cell (SOFC) technology incorporates electrochemical reactions that generate electricity and high quality heat. The coupling of this technology with gas turbine bottoming cycles, to form hybrid power systems, leads to high efficiency levels. The purpose of this study is to conceptually integrate the hybrid power system with existing and imminent coal gasification technologies. The gasification technologies include the Kellogg Brown Root (KBR) Transport Reactor and entrained coal gasification. Parametric studies will be performed wherein pertinent fuel cell stack process settings such as operation voltage, inverse equivalence ratio and fuel utilization will be varied. Power output, system efficiency and costs will be the dependent variables of interest. Coal gasification data and a proven SOFC model will be used to test the theoretical integration. Feasibility and economic comparisons between the new integrated system and existing conventional systems will also be made.
