The micro gas turbine (MGT) system for the biomass gas has been constructed. This system consists of MGT power generation system, mock biomass gas supply system and control system. The features technologies in this system are two-stage combustor and H infinity system controller. The combustor achieves both higher combustion efficiency and lower NOx emission, in which a stable tubular flame combustion of the first stage supplies burned gas to the second stage and causes stable ignition and combustion of biomass gas and air pre-mixture. H infinity algorithm is employed as a system controller for its robustness for disturbances like as unpredictable fuel component fluctuation. By using this MGT system, operation test was carried out with mock biomass gas. Rotational speed of the power turbine could be kept constant with both fermentation gas and pyrolysis gas, and NOx emission was low. The speed could be also kept constant, even when the fuel composition or load changed.
