What is the economic benefit of setting up biogas in our country? This is a problem that many people are very concerned about. Based on the results of random sampling, macroscopic investigation and comparative analysis, this paper discusses the biogas investment benefits, heat transfer efficiency and comprehensive benefits. First, the investment effect is significant China is running the use of digesters have millions of mouth, the investment effect of these digesters is significant, both in terms of random sampling test results from the point of view or macroscopically can be seen from the results Out of this conclusion.
