    Development of the integrated gasification combined cycle power generation of various gasifying meth-ods has been preceded in the world. The gasified fuels are chiefly characterized by the gasifying agent and the synthetic gas clean-up method, and divided roughly into four types. The calorific value of gasified fuel differs according to the type of gasification agent. On the other hand, to improve the thermal efficiency. it is necessary to use a hot/dry type synthetic gas clean-up, but ammonia originated from nitrogenous compounds in coal is not removed. And then it forms fuel-NOx. For these reasons, the combustion technology for each gasified fuel is important. In this paper, I review development of the gas turbine combustors for the gasified fuels of three types through numerical analyses, experiments using a small burner and the designed combustors.

    Introducing a co-generation system is an effective choice for reducing energy derived CO2 emissions and operating costs for the residential and commercial sectors. In this paper, the possibilities of CO2 emission and operating cost reductions were investigated for the case of a micro gas turbine co-generation system being introduced into a 33 household apartment building located in Sapporo, one of the coldest districts in Japan, which demands a lot of energy in winter for hot-water supply and heating.
    The results were compared with that of the existing system which is composed of an electricity grid and hot water boilers. The CO2 emissions and operating costs of the co-generation system varied according to the ratio of electricity supply from the grid and MGT, MGT generation efficiencies and the season of the year. Using an MGT with an electricity generation efficiency of 35%, a reduction of 10% (23.4 tonne-CO2/y) of CO2 emissions and 9.4% (433ky) of operating costs could be attained compared with the existing system. In the case of a generation efficiency of 30%, a reduction of 3.4 tonne-CO2/y is expected at the same level of operating cost as the existing system. But in the case of a generation efficiency of 25%, there was no signifi-cant reduction in CO2 emission.

    Reaction rates of methane steam reforming for hydrogen production at low temperatures 400-525°C were measured to establish the rate expression. A 2wt% ruthenium supported alumina was used as a catalyst. As the measured rates were analyzed based on the Langmuir-Hinshelwood mechanism, it was found that the surface reaction between methane and water adsorbed was the rate-determining step and the following expression could well explain the kinetic data obtained experimentally.
