摘要：
In order to find out the heating heat source of economic and saving energy for digester, the digester conventional heating method was analyzed. A new method of heating digester by geothermal energy from mine was proposed. The digester heating test system was designed using mine geothermal water as heating source. The results show that digester liquid temperature can be kept at fermentation temperature through heating, and gas production increases significantly. Compared with other heating methods, the new method has economic and environmental benefit.
