Extended Abstract In recent years, the effective use of low grade fossil fuel and the diversity of fuels are required due to the exhaustion of fossil fuels, global warming and the nuclear accident caused by the Tohoku earthquake in Japan. The studies of brown coal, biomass, biofuel, etc. are being conducted to expand the use of these fuels throughout the world. We have paid attention to biogas among such low grade fuels. Biogas is a carbon neutral fuel to be generated from garbage, livestock manure, sewage sludge, etc. CO2 emitted by its combustion is not converted to greenhouse gases. On the other hand, biogas is primarily composed of 60% CH4 and 40% CO2, and has a low calorific value. Low calorific value does not make biogas easy to apply to a conventional energy utility system. To utilize biogas, it is necessary to develop the combustion promotion technology of biogas or upgrade biogas.
