Research and Analysis of Solar Heating Biogas Fermentation System

Firstly this paper designs solar heating biogas fermentation system, its volume is 6m3, and than calculates digester's heat load based on Hohhot's weather data. Finally, a U-tube collector system was carried out for 5 month experiment, this paper use October's experimental data, looking for the heat matching relationship between the solar collector system and biogas fermentation system. We can conclude that at Hohhot, in October, the heat was absorbed by 2m2 solar collectors that was ran 8 hours can met the 6m3 digester ‘s fermentation heat demands.
