Using biogas to warm and insulate greenhouses

Combustion of 1 cubic meter of biogas can release approximately 23,000 kilojoules of heat, and this data is used to determine the amount of heat needed to increase the temperature and keep warm in different volumes of greenhouses. For example: The greenhouse is 20 meters long, 7 meters wide, 1.5 meters high and 210 cubic meters in volume. About 1 kJ of heat is required to increase 1°C per cubic meter of air temperature. To increase the 210 cubic meters of greenhouses by 10 degrees, it is necessary to burn methane gas = 0.1 cubic meters without taking into account heat dissipation. Because of the low insulation performance of the greenhouse, most of the heat is lost quickly. Normally, one biogas stove or 50 m2 of biogas stove is installed in a greenhouse for every 10 square meters, and the heat generated by stoves and lamps is used for heat preservation. The lights are always on, constantly cooling, and the gas stoves are used when the temperature is raised at a faster time.
