Multi-stage gasification combined with internal combustion gas engine is an efficient way of combined heat and power production (CHP) from woody biomass. In this work the performance of a multi-staged fix bed gasifier is reported. In this type of generator, all subsequent processes like pyrolysis, partial oxidation of vola-tile matter and gasification of char take place in different parts of the generator. The used multi-stage concept enables to increase cold gas efficiency over 80 % and produce a clean gas with low tar content. Another advantage is the possibility of controlled biochar production. The same multi-stage gasifier design was used in eleven cogeneration units built in the Czech Republic with an electrical output from 200 to 750 kW. This study presents the experience with operation of the largest CHP facility in the Czech Republic. The CHP fa-cility consists of five generators with a maximum electrical power of 750kW each.
