沼气发电机组相关参数

　　Relevant parameters of biogas generator set

　　一、沼气发电简介

　　1、 Introduction to Biogas Power Generation

　　沼气发电机组是以生物质发酵产生的沼气经过净化处理后，在燃气内燃机气缸中压缩点燃做功进行发电的设备。沼气是将人畜粪便、庄稼秸秆等有机物在隔绝空气（还原条件），并在适宜的温度、湿度下，经过微生物的发酵作用产生的一种可燃烧气体。沼气的主要成分是甲烷，甲烷是一种理想的气体燃料，它无色无味，与适量空气混合后即燃烧。每立方米纯甲烷的发热量为34000焦耳，每立方米沼气的发热量约为20800－23600焦耳。即1立方米沼气完全燃烧后，能产生相当于0.7千克无烟煤提供的热量。将厌氧池密闭,收集沼气,然后配一台沼气发电机就可以了利用这种可燃气体发电，就是沼气发电。

　　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. 沼气的成分：

　　1. Composition of biogas:

　　沼气是一种混合气体，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% ，还有少量氢、一氧化碳、硫化氢、氧和氮等气体。由于含有可燃气体甲烷，故沼气可做燃料。沼气是细菌在厌氧条件下分解有机物的一种产物。城市有机垃圾、污水处理厂的污泥、农村的人畜粪便、作物秸秆等，皆可做产生沼气的原料。

　　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.
