沼气池热传递过程研究进展

Progress in Anaerobic Digester Heat Transfer

温度是沼气工程高效运行的关键,沼气发酵不仅要维持适宜的温度,还须保证温度的稳定性。为此,对沼气池热传递过程的相关研究进行分析介绍,主要包括沼气池发酵液温度的影响因素、发酵系统热流损失、增温方式和热传递模型研究,并指出增温方式的选择应建立在正确的热过程分析基础上,建议进一步改进优化热传递模型,更好地指导沼气工程实施。

Temperature is the key factor to anaerobic digester, which should be maintained at a proper temperature and thermal stabilization. The digester heat transfer progress had been analyzed in this paper, including influent factors of liquid temperature, digester heat loss, heat means and heat transfer model. It indicated that heat means should be according to correct thermal rule and anaerobic digester. Further research is suggested to optimize heat transfer model, in order to better guidance the running of biogas plant.
