Study on Economic Heating Source for Mesophilic Fermentation in a Rural Biogas Plant

摘要

The paper introduces a new technology making a rural biogas plant of mesophilic fermentation, the key of which is a set of efficient installation recovering waste heat from a biogas-diesel engine. The system exhausts no extra energy and waste heat recovered from the engine can entirely make compensation for a heat loss of the biogas plant, which is an economic heating source for mesophilic fermentation. If spreas and use, the new technology would make great contribution to yearlong steady efficient output of a rural biogas plant and make biogas a reliable energy resource in the countryside.
