沼气发电机组是一种集环保与节能为一体的能源综合利用新技术。它利用工业、农业或城市生活中的大量有机废弃物（如酒糟、牲畜粪便、城市垃圾和污水等），利用厌氧发酵产生的沼气驱动沼气发电机组产生电，可充分转化沼气发电机组的余热用于沼气生产。

Biogas generator set is a new energy comprehensive utilization technology integrating environmental protection and energy conservation. It uses a large number of organic wastes in industry, agriculture or urban life (such as lees, livestock manure, urban garbage and sewage), and uses the biogas generated by anaerobic fermentation to drive the biogas generator set to generate electricity, which can fully convert the waste heat of the biogas generator set for biogas production.

我国沼气发电研发已有多年历史。目前，国内0.8-5000kw各种容量的沼气发电机组已确定并投入运行。主要产品全部使用沼气纯沼气发动机，部分使用沼气的双燃料沼柴油发动机。.

The research and development of biogas power generation in China has a long history. At present, 0.8-5000kw biogas generating units with various capacities in China have been determined and put into operation. The main products all use biogas pure biogas engines, and some use biogas dual fuel biogas diesel engines

沼气发电热电联产项目的热效率因发电设备而异。例如，如果使用燃气内燃机，热效率在70%到75%之间。在某些情况下，热效率可以达到90%以上。

The thermal efficiency of biogas power cogeneration projects varies with the power generation equipment. For example, if a gas-fired internal combustion engine is used, the thermal efficiency is between 70% and 75%. In some cases, the thermal efficiency can reach more than 90%.

发电机组本身的沼气发电技术提供了清洁能源，不仅解决了沼气工程中的环境问题，消耗大量垃圾，保护了环境，减少了温室气体的排放，而且变废为宝宝物并产生大量热能。符合能源循环利用的环保理念，也带来了巨大的经济效益。

The biogas power generation technology of the generator set itself provides clean energy, which not only solves the environmental problems in biogas engineering, consumes a lot of garbage, protects the environment, reduces greenhouse gas emissions, but also turns waste into baby stuff and generates a lot of heat energy. In line with the environmental protection concept of energy recycling, it has also brought huge economic benefits.

这些机组各有特色，技术突破，结构新颖，已在我国部分农村、有机废水、垃圾填埋场沼气工程中得到应用。近十年来，由于农村家庭联产承包责任制、大中型工业化养殖场的建立和环境保护，我国沼气发电机组和沼气发电机组发展到两极。

These units have their own characteristics, technological breakthroughs and novel structures, and have been applied in some rural areas, organic wastewater and landfill biogas projects in China. In the past decade, due to the rural household contract responsibility system, the establishment of large and medium-sized industrialized farms and environmental protection, China's biogas generating units and biogas generating units have developed to two poles.

农村主要向小功率沼气发电机组和沼气发电机组方向发展，酒厂、糖厂、畜牧养殖场、污水处理厂等大中型环保能源项目主要向高功率方向发展。-动力沼气发电机组。

Rural areas are mainly developing towards low-power biogas generating units and biogas generating units, and large and medium-sized environmental protection energy projects such as distilleries, sugar factories, animal husbandry farms, sewage treatment plants are mainly developing towards high-power- Power biogas generator set.
