Abstract

In this article, in order to determine the consumption of thermal energy for biomass processing, modeling and calculation of the thermal balance of a pyrolysis plant are performed. Based on these equations, the calculation of parameters such as the thermal balance for a tubular (cylindrical shape) bioreactor, the heat used, the efficiency of the tubular bioreactor, the exergy of the source fuel, the exergetic efficiency of the bioreactor, the loss of exergy to the environment, the heat transfer coefficient, etc. The heat balance calculation software is developed using the Java programming language. In addition, the article provides a comparative analysis of the technical and energy characteristics of bioenergy plants, which shows that the energy intensity of biomass processing in existing plants reaches up to 50-60% in the total heat balance.
