Abstract

This paper presents the numerical study and optimization of CHP power plant consisting of gasification process, solid oxide fuel cell and micro gas turbine. Woody biomass is converted to product gas in the gasification part, and in the CHP producing part, the product gas is converted to electric power and heat by use of a solid oxide fuel cell stack, micro gas turbine and heat recovery steam generator. The model used in the gasification process is a modified thermodynamic equilibrium model, and the steady-state intermediate temperature solid oxide fuel cell model developed hear is one-dimensional which allows for monitoring of the temperature gradients along the cell length under different operating conditions. Zero-dimensional models are used for other components. The effects of main cycle parameters, such as; the gasification agent, average current density and the fuel utilization factor on the cycle important outputs; cooled gas efficiency, temperature gradients, the electric and CHP efficiencies, and the total electric power of the plant are investigated. After extensive parametric analysis, multi-objective genetic algorithms (NSGA II) is then used for Pareto based optimization of CHP plant in two steps. The maximum electric power and electric efficiency are 206/81 kW and 46/27% respectively.
