Abstract

The article develops a mathematical model of the modes of change of the indoor air temperature and the loaded biomass temperature over time on the basis of the equilibrium heat balance equation of the reactor of the heat pipe biogas-biofertilizer. Theoretical and experimental studies of changes in air temperature over time in stationary and non-stationary states inside the reactor of a thermal tubular biogas-biofertilizer. According to the results of the study, when the outside air temperature is 10 ºС, it is possible to heat the indoor air temperature to 85-90 ºС in accordance with the total solar radiation falling on the transparent surface of the device reactor. It is scientifically based to achieve full coverage of the greenhouse heat load using heated water due to the combustion of biogas obtained anaerobically in a water heating boiler as a result of heating of the biomass inside the device.
