The Chemically Recuperated Gas Turbine (CRGT) system is an advanced GT cycle that converts the fuel into the hydrogen-rich gas by recovering the exhaust heat from the gas turbine. The principal reaction of fuel conversion is steam reforming. This report shows the demonstration of power generation test by the DME-fueled CRGT using the 30kW micro gas turbine (MGT). The heat recovery system, which mainly consists of the steam evaporator and the DME steam reformer, was directly installed into the exhaust gas duct. The power generation test, combining the MGT generator set, all heat recovery equipments and the supply systems of DME and demineralized water, were conducted. As a result, the power generation efficiency of CRGT was improved approximately 10% compared to the efficiency of the steam injection GT cycle which was a proven technology, and lOppm or less NOx emission from the MGT was attained.
