- The development of an improved process for decentralised combined heat and power generation from biomass gasification was the main goal of this project. Based on gasification tests performed in a bench-scale pressurised fluidised gasifier a concept for an allothermal gasification unit was made. Air-blown as well as steam-blown tests were carried out considering three different kinds of biomass (birch, salix, and crushed pelletised straw) against a wide spectrum of operation conditions with different bed-materials (silica sands, magnesite and dolomite). The aim of the gas quality optimisation was the production of a fuel gas (syngas) with a high H2 and low tar content suitable for a gas engine. The tar content was measured with SPA method and a gravimetric method. The tests were performed at the Royal Institute of Technology, Stockholm, in close co-operation with the University of Essen. Jenbacher AG designed a new type of cylinder head for the direct feeding of the hot pressurised syngas into the gas engine in co-operation with the Technical University of Graz. Taking the results obtained into account a concept of decentralised combined heat and power generation (CHP) unit with an electrical power output of 1 MW was set up.
