The article deals with a highly actual theme of wood biomass exploitation for energy purposes, specifically problems of wood gas production and purification systems in relation to the requirements of combustion engines. Wood matter gasification represents one of the ways of alternative exploitation of wood matter in power engineering. The paper deals with filter efficiency and effectiveness evaluation by means of adsorption cartridge filters. The evaluation was carried out on a basis of determination of the ingoing and outgoing change of solid particles concentration in wood gas during a continuous 4 – hours loading. The evaluating criterion was an acceptable value of contaminants in wood gas for its utilization in combustion engines.Článok...
