Abstract

A new concept of a gas turbine/steam turbine combined cycle system, referred to as the “ Chemical Gas Turbine” system, is proposed in order to raise the total thermal efficiency of existing systems. The characteristics of this system are a combustor operating under fuel-rich conditions, and C/C composites material adopted for fabrication of the turbine blade. This system consists mainly of two gas turbines and a steam turbine, and has advantages that exergy loss and total NOx products are decreased by means of fuel-rich combustion. The purpose of this work is to demonstrate the advantage of the chemical gas turbine system, and the thermal efficiency of this system and total NOx products are simulated. Besides, we convert a commercial small-scale gas turbine into the micro chemical gas turbine, and develop combustor for fuel-rich combustion of methane-air and related equipment. After that, we examine the fundamental working characteristics of the assembled system. The results show th feasibility of such a chemical gas turbine system.
