Energy and economic effects of chp with combined technologies of corn cobs gasification and gas turbines

Abstract

This paper presents the performance and economic analysis of the gas turbine with co-firing gas from corn cob gasification and natural gas. Adiabatic and non--adiabatic expansion in the turbine is considered. The analysis is performed par-ametrically with corn cob gasification gas and natural gas ratio. The volumetric energy content of fuels with different share of gas from the corn cob gasification, therefore, with different calorific values, is compared by means of the Wobbe In-dex. In energy and economic analyses, the following configurations are dealt with: single manifold, dual manifold, and separate gas systems.
