Analysis of the amount of ash during sessile oak (Quercus petraea, Mattuschka) wood combustion

Abstract

The subject of investigation in this paper is the amount of ash residue during combustion of Sessile oak (Quercus petraea, Mattuschka) wood that is one of the most usable ones as fire wood in households in the Republic of Macedonia. The purpose of this investigation was to establish the amount of ash, as one of the biggest problems during energy production with forest biomass. The material for this investigation is collected from two different regions of the State, in order to eliminate or to emphasise the influence of different stand conditions. The results from the investigation show that during the sessile oak wood combustion the wood produces less ash than wood with bark, and bark produces the highest amounts of ash.
