Biogas power generation has many advantages, such as efficiency, energy saving, safety and environmental protection. It is a widely distributed and cheap distributed energy market. Market research shows that biogas power generation has attracted extensive attention and actively promoted in developed countries. Biomass power generation grid connected in Western Europe, some countries accounted for about 10% of total energy. Biogas power generation technology is a new technology of energy comprehensive utilization which integrates environmental protection and energy saving.
It is the use of a large number of organic waste industry, agriculture or urban life, the biogas anaerobic fermentation treatment, biogas power generation waste heat driven, and fully generating units for biogas production. The thermal efficiency of biogas power cogeneration projects, as power devices are different and the difference is larger, such as the use of gas engine, its thermal efficiency is between 70%~75%, and such as the use of gas turbine and boiler, in afterburning condition, the thermal efficiency can reach above 90%.
Biogas power generation technology itself is clean energy, not only to solve the environmental problems, the biogas project in consume a lot of waste, protect the environment, reduce greenhouse gas emissions, and waste, produced a lot of energy and electrical energy, with energy recycling concept of environmental protection, but also bring huge economic benefits. The methane generator is through the vertical landfill in a plurality of implanted extraction well, uninterrupted gas extraction, through the collection pipe to the generator unit, after cooling desulfurization dehydration, filtration and purification process, produce pure methane combustion in power generating units in power generation, and then connected to the grid.
沼气发电原理： 首先就是要先从沼气讲起，沼气是部分有机物经过封闭式的厌氧发酵，发酵后就会含有部分沼气，然后经过收集。现在大部分都是生活垃圾或者污水COD含量高的企业沼气量比较充足。然后在开始说沼气的成分，沼气中的成分非常混杂，其中甲烷的含量是比较高的。而且甲烷是一种可燃性气体，热值也比较高。 收集后的沼气通过发电机组的发动机进行燃烧做工，就是内燃机形式，由做工后的扭矩带动发电机的转子绕组进行做工，完成发电流程。
Biogas power generation principle: first of all, it is necessary to start from biogas, biogas is part of organic matter, through closed anaerobic fermentation, fermentation will contain some methane, and then collected. Now, most of them are domestic waste or sewage, and the enterprises with high COD content are relatively abundant in methane. Then, when it comes to biogas, the ingredients in methane are very mixed, of which methane content is relatively high. What's more, methane is a flammable gas with relatively high calorific value. After the collection of methane through the engine of the generator set combustion work, that is, the form of internal combustion engine, by the torque after work to drive the generator rotor winding work, complete the power generation process.
