　　Relevant parameters of biogas generator set

　　一、沼氣發(fā)電簡介

　　1、 Introduction to Biogas Power Generation

　　沼氣發(fā)電機組是以生物質(zhì)發(fā)酵產(chǎn)生的沼氣經(jīng)過凈化處理后，在燃氣內(nèi)燃機氣缸中壓縮點燃做功進行發(fā)電的設(shè)備。沼氣是將人畜糞便、莊稼秸稈等有機物在隔絕空氣（還原條件），并在適宜的溫度、濕度下，經(jīng)過微生物的發(fā)酵作用產(chǎn)生的一種可燃燒氣體。沼氣的主要成分是甲烷，甲烷是一種理想的氣體燃料，它無色無味，與適量空氣混合后即燃燒。每立方米純甲烷的發(fā)熱量為34000焦耳，每立方米沼氣的發(fā)熱量約為20800－23600焦耳。即1立方米沼氣完全燃燒后，能產(chǎn)生相當于0.7千克無煙煤提供的熱量。將厭氧池密閉,收集沼氣,然后配一臺沼氣發(fā)電機就可以了利用這種可燃氣體發(fā)電，就是沼氣發(fā)電。

　　A biogas generator set is a device that generates electricity by compressing and igniting the purified biogas produced by biomass fermentation in the cylinder of a gas internal combustion engine. Biogas is a combustible gas produced by the fermentation of organic matter such as human and animal manure, crop straw, etc. in isolated air (reducing conditions) and under suitable temperature and humidity conditions by microorganisms. The main component of biogas is methane, which is an ideal gas fuel. It is colorless and odorless, and when mixed with an appropriate amount of air, it burns immediately. The calorific value of pure methane per cubic meter is 34000 joules, and the calorific value of biogas per cubic meter is approximately 20800-23600 joules. After complete combustion of 1 cubic meter of biogas, it can generate heat equivalent to 0.7 kilograms of smokeless coal. Seal the anaerobic tank, collect biogas, and then equip it with a biogas generator to generate electricity using this combustible gas, which is biogas power generation.

　　1. 沼氣的成分：

　　1. Composition of biogas:

　　沼氣是一種混合氣體，主要成分是甲烷(CH4)和二氧化碳(CO2，)。甲烷占45%～70%，二氧化碳占30%～40% ，還有少量氫、一氧化碳、硫化氫、氧和氮等氣體。由于含有可燃氣體甲烷，故沼氣可做燃料。沼氣是細菌在厭氧條件下分解有機物的一種產(chǎn)物。城市有機垃圾、污水處理廠的污泥、農(nóng)村的人畜糞便、作物秸稈等，皆可做產(chǎn)生沼氣的原料。

　　Biogas is a mixed gas composed mainly of methane (CH4) and carbon dioxide (CO2). Methane accounts for 45% to 70%, carbon dioxide accounts for 30% to 40%, and there are also small amounts of gases such as hydrogen, carbon monoxide, hydrogen sulfide, oxygen, and nitrogen. Due to the presence of combustible gas methane, biogas can be used as fuel. Biogas is a product of bacteria decomposing organic matter under anaerobic conditions. Urban organic waste, sewage treatment plant sludge, rural human and animal manure, crop straw, etc. can all be used as raw materials for producing biogas.
