Research of integrated biomass gasification system with a piston engine

The article presents the issue related to power production from gas received during biomass gasification process and advantages of biomass gasification technology use in cogeneration systems. Research installation for power production from biomass (~ 60 kW_t), developed at the Institute for Chemical Processing of Coal in Zabrze, is characterized. The installation consists of a fuel supply system, gas generator with fixed-bed, dry gas cleaning system and the system used to produce electricity. The article describes installation development process which was divided in three staged. The influence of four different biomass available on polish market, on quality of received process gas i s presented as well as received reduction efficiencies of dust and organic contaminations in proposed new conception of dry purification of gas system. Power generation system supplied by process gas, equipped with dual fuel combustion engine with rated power of 25 kW is presented. The article presents results of work of power generation system for production of 8 and 15 kW of electricity, by engine supplied with diesel oil and process gas.
