ABSTRACT

Use of the crop biomass in the energy production is one of the preconditions to avoid ecological disasters in future and to compensate growing shortage of fossil energy sources. Ash is the non-combustible component of biomass, and high content thereof leads to fouling problems. Biomass fuels tend to have high ash and potassium contents; as a result, ash melts at lower temperatures and leads to dross that can obstruct furnace elements and cause their damage. The aim of the study was evaluation of factors influencing potassium content in energy crop pellets. Pellets prepared within the research had different proportions (1/3, 1/1, 3/1) of reed canary grass (RCG) variety ’Marathon’ and energy wood – poplar. The research resulted in finding potassium content in RCG and poplar pellets, correlations with lignin content, combustion ability and ash content, as well as in suggestions on optimum biomass content and proportions for the pellet production.
