ABSTRACT
The paper focuses upon possibilities for the production and subsequent use of briquettes made from a mixture of wood waste and wood ash. Ash samples were obtained from incineration in power stations to create biomass with an output of 4.6 MW.h-1. The power station annually consumes 50,000 tons of waste biomass which is created when processing fir and spruce timber. Several ratios of sawdust mixed with wood ash residue were tested. The best results were found using briquettes made in a ratio of 2:1 (sawdust : wood ash). The calorific value of such produced briquettes is 15.83 MJ.kg-1. The briquettes may fully replace wood or coal.
