Changes in biomass energy parameters depending on the harvest season

Abstract

The harvested period of energy grasses can change considerably the problem parameters which influence the process of combustion (concentrations of alkalies, chlorine, nitrogen and ash). The highest losses of water-soluble potassium (> 80 %) were observed for Agrostis gigantea Roth. and Phalaris arundinacea L., the lowest losses were found for Festuca arundinacea Schreb. The losos of water-soluble sodium (36 – 57 %) were Loir than those of potassium. The concentration of chlorine remained almost constant during whole vegetation period.
