The use of biomass and waste for decentralised combined heat and power production (CHP) requires highly efficient gasification processes. In the Technische Universitat Munchen (TUM), an innovative gasification technology has been developed. This allothermal gasifier is producing a hydrogen-rich, high-calorific gas, that can be further used in a microturbine or a fuel cell producing energy. For the operation of such a system, the online analysis of the composition of the product gas is of high importance, since the efficient working of the machines is linked with the gas quality. For this purpose an optical measurement system based on laser spectroscopy has been applied. This system can measure not only the basic components of the product gas (H-2, CH4, CO, CO2, H2O), but it also gives information concerning the content of high hydrocarbons, the so-called tars, in the product gas.
