ABSTRACT
The article presents the comparative analysis of three types of solid biofuels from various wastes: pellets from sunflower husks made from waste production; wood pellets made from waste wood and pellets on the basis of thermally modified raw materials - as a way to increase calorific characteristics of biofuel.
The chemical composition of these types of fuels has been analyzed. The results of studies on the combustion of the fuels and their calorific value are presented. The author suggests that the fuel pellets from sunflower husks on quality are not inferior to wood pellets: at a lower cost of raw material combustion in the boiler furnace is not less effective. In addition, the possibility of increasing the efficiency of solid fuels by thermal treatment has been confirmed. Due to this fact, pellets from sunflower husks have high competitiveness in comparison with the analogues and can be widely used.
