THERMAL PERFORMANCE INDICATORS OF BIOGAS OBTAINED AS A RESULT OF PROCESSING ORGANIC BIOMASS

Biomass processing under anaerobic conditions is carried out in special, pressurized digesters (Fig. 1). Under the influence of methane-forming bacteria in an oxygen-free environment at a temperature of 30 ... 55 ° C, the biomass is fermented in the reactor with the formation of combustible gas - biogas, which is used for technological and domestic needs. About 1 mt of manure with 90oñ humidity can produce about 220 m3 of biogas with a calorific value of 28 ... 35 MJ/m3. The remains of the fermentation mass in the digesters are a highly digestible liquid highly concentrated organic fertilizer (humus) easily digestible by plants and devoid of pathogens and weed seeds [8,9].
