Feasibility Analysis of Solar Constant Temperature Biogas Production System

This paper introduces a new solar constant temperature biogas production system. Aiming at the influence of environmental temperature change on biogas production system, the hardware circuit and software program of temperature control system are designed. The system takes single chip microcomputer as the core, and uses solar energy collecting module to heat biogas system to improve the gas production rate and stability of biogas digester. The results show that: during the test period, the biogas produced every day is 1m3, the cumulative annual gas production is 398.52m3, the system can reduce CO2 emissions of about 8085kg, NOx emissions of about 23.1kg.
