Biogas technologies in the heat and gas supply systems for the agricultural organizations in the Saratov region

Abstract

One of the advantages of using biogas plants is the biogas production to generate thermal energy. The useful consumption of generated energy depends on the biogas plant’s thermal protection optimization level. The purpose of the study is to search for technical solutions and justification of optimal parameters for increasing the energy efficiency of a biogas plant used in the thermal energy generation to create a favorable microclimate in livestock buildings. The design and technological features of a biogas plant depend on the process stages, the shape of the reactor, and the types of mixing. The criteria for energy efficiency are the lowest cost of energy consumed by a biogas plant for its own needs. A comparison of the insulating materials’ energy indicators made it possible to establish that cellulose wool and polystyrene foam have the lowest heat transfer coefficients.
