A method of estimation of the caloric value of the biomass. Part I – biomass energy potential
Abstract
The caloric value of the crops is one of the fundamental parameters to be determined during the process of biomass production for the energy purposes. The variety of biomass and its reaction to the environmental and agrotechnical conditions forces the utilization of particularly accurate algorithms during the determination of the caloric value of the crops. While determining the caloric value of the directly combusted crops, the coefficients for the raw state caloric value should be used. Violation of this rule causes significant overestimation of the end-results. Using the biomass for the biogas production, the energy balance should take the methane into account. The literature data shows quite a big difference in gas production from various substrates (from 368 up 722 Ndm3 per kg of dry mass) as well as a significant difference in the methane content (from 53 up to 76%). While planning the substrates selection for a biogas production plant, special attention should be put on proper estimation of the overmentioned coefficients.
