This thesis deals with combustion of lignocelluloses biomass with comparison to cellulose-lignin biomass and with appropriateness of different combustion technologies in the context of the impact on the environment. Furthermore, the thesis deals with content of the heating value in the individual fuels. The heating value capacity was measured experimentally in different kinds of biomass by method of dry distillation and these results were statistically evaluated and and discussed with the findings taken from literature. On the basis of literature data, differences have been discovered in lignocelluloses fuels in terms of calorific value and heating value, calorific values were in average from 15,3 MJ/kg to 16,8 MJ/kg and heating values were 17,5 18,1 MJ/kg. While in cellulose-lignin fuels these differences are not that big and are within values of 19,5 MJ/kg for heating value and an average calorific value is around 18,4 MJ/kg. Measuring of the content of tar and other residual fluid fractions in five the most commonly used bio-fuels from agricultural production (wheat straw, rape straw, hay, energy crops, digestate from biogas station). After statistical evaluation of data, it revealed the difference in content of tar between the wheat straw and digestate (P 0,05; on average 40,48 % for wheat straw and 29,58 % for digestate).
