A novel concept of a gas turbine/steam turbine combined cycle system, ″Chemical Gas Turbine″, was proposed to raise the total thermal efficiency of existing systems. The system's characteristics include a combustor operating under fuel-rich conditions, and C/C composites material adopted for fabrication of the turbine blade. It consists mainly of two gas turbines and a steam turbine. Energy loss and total NOx products are decreased by means of fuel-rich combustion. The system's advantages, thermal efficiency, and total NOx products were demonstrated. A commercial small-scale gas turbine was converted into the micro chemical gas turbine, and a combustor for fuel-rich combustion of methane-air and related equipment was developed. An examination of the fundamental working properties of the assembled system showed the feasibility of such a chemical gas turbine system. Original is an abstract.
