沼氣發電具有創效、節能、安全和環保等特點，是一種分布廣泛且價廉的分布式能源. 市場研究表明沼氣發電在發達國家已受到廣泛重視和積極推廣。

Biogas power generation has the characteristics of efficiency, energy conservation, safety, and environmental protection, and is a widely distributed and cost-effective distributed energy source Market research shows that biogas power generation has been widely valued and actively promoted in developed countries.

生物質能發電并網在西歐一些國家占能源總量的10%左右。 沼氣發電技術是集環保和節能于一體的能源綜合利用新技術。它是利用工業、農業或城鎮生活中的大量有機廢棄物(例如酒糟液、禽畜糞、城市垃圾和污水等)，經厭氧發酵處理產生的沼氣，驅動沼氣發電機組發電，并可充分將發電機組的余熱用于沼氣生產。

Biomass energy grid connection accounts for about 10% of the total energy in some Western European countries. Biogas power generation technology is a new energy comprehensive utilization technology that integrates environmental protection and energy conservation. It utilizes a large amount of organic waste from industry, agriculture, or urban life (such as distiller's grains, livestock manure, urban garbage, and sewage), and produces biogas through anaerobic fermentation to drive the biogas generator set to generate electricity, and can fully utilize the waste heat of the generator set for biogas production.

沼氣發電熱電聯產項目的熱效率，視發電設備的不同而有較大的區別，如使用燃氣內燃機，其熱效率為70%~75%之間，而如使用燃氣透平和余熱鍋爐，在補燃的情況下，熱效率可以達到90%以上。

The thermal efficiency of biogas cogeneration projects varies greatly depending on the type of power generation equipment used. For example, if a gas internal combustion engine is used, its thermal efficiency ranges from 70% to 75%. However, if a gas turbine and waste heat boiler are used, the thermal efficiency can reach over 90% with supplementary combustion.

沼氣發電技術本身提供的是清潔能源，不僅解決了沼氣工程中的環境問題、消耗了大量廢棄物、保護了環境、減少了溫室氣體的排放，而且變廢為寶，產生了大量的熱能和電能，符合能源再循環利用的環保理念，同時也帶來巨大的經濟效益。

The biogas power generation technology itself provides clean energy, which not only solves environmental problems in biogas engineering, consumes a large amount of waste, protects the environment, and reduces greenhouse gas emissions, but also turns waste into treasure, generating a large amount of heat and electricity, in line with the environmental protection concept of energy recycling and utilization, and also brings huge economic benefits.

沼氣發電機是通過垂直植入垃圾堆體里若干根抽氣井，不間斷將沼氣抽出，經過收集管網送至發電機機組，再經過冷卻脫硫脫水、過濾凈化等處理后，產生的純沼氣在發電機組里燃燒后發電，再并入電網。

A biogas generator is a type of generator that continuously extracts biogas by vertically implanting several extraction wells into the garbage heap. The biogas is then collected through a collection pipeline and sent to the generator unit, where it is cooled, desulfurized, dehydrated, filtered, and purified. The resulting pure biogas is burned in the generator unit to generate electricity, which is then integrated into the power grid.

沼氣發電原理： 首先就是要先從沼氣講起，沼氣是部分有機物經過封閉式的厭氧發酵，發酵后就會含有部分沼氣，然后經過收集。現在大部分都是生活垃圾或者污水COD含量高的企業沼氣量比較充足。然后在開始說沼氣的成分，沼氣中的成分非常混雜，其中甲烷的含量是比較高的。而且甲烷是一種可燃性氣體，熱值也比較高。 收集后的沼氣通過發電機組的發動機進行燃燒做工，就是內燃機形式，由做工后的扭矩帶動發電機的轉子繞組進行做工，完成發電流程。

The principle of biogas power generation: First of all, we need to start with biogas. biogas is a closed anaerobic fermentation of some organic matter, and after fermentation, it will contain some biogas, which is then collected. Nowadays, most enterprises with high COD content in household waste or sewage have sufficient biogas production. Then, when it comes to the composition of biogas, the components are very mixed, with methane content being relatively high. Moreover, methane is a combustible gas with a relatively high calorific value. The collected biogas is burned through the engine of the generator set, which is in the form of an internal combustion engine. The torque after the work drives the rotor winding of the generator to complete the power generation process.
