Recently, the biomass gas is remarked as renewable energy. The practical use for the fuel is reported. Some of biomass gas are produced by the gasification with the gas furnace and the others are collected by sewerage processing. The gas includes various species of components which are such inert gas as Nitrogen N2, carbon dioxide gas CO2 and flammable components as hydrogen H2, methane CH4 and carbon monoxide CO. The fuel calorific value depends on the ratio of each component. In this study, the diffusion flame is formed when the biomass gas spouts from the burner nozzle. The practical biomass gas BG and dilute hydrogen H2 with mixing Nitrogen N2 are used as the fuel. The characteristic of combustion with the low-calorie gas fuel is investigated. As for the practical use, the engine is operated by using the biomass gas. The performance of the engine and the components of exhaust gas are measured. It is found that the biomass gas is effective as renewable fuel.
