沼氣發(fā)電工藝流程：沼氣池-沼氣-脫水脫硫-氣水分離-過濾-壓縮-氣水分離-冷卻-發(fā)電機組-配電室-用戶-循環(huán)冷卻。根據(jù)沼氣發(fā)電機組的工作特點，在組建沼氣發(fā)電機組系統(tǒng)時，要著重考慮以下幾個方面：

Biogas power generation process flow: biogas digester - biogas - dehydration and desulfurization - gas water separation - filtration - compression - gas water separation - cooling - generator set - power distribution room - user - circulating cooling. According to the working characteristics of the biogas generator set, the following aspects should be considered when establishing the biogas generator set system:

1、沼氣脫硫及穩(wěn)壓、防爆裝置：沼氣中含有少量的H2S，該氣體對發(fā)動機有強烈的腐蝕作用，因此供發(fā)動機使用的沼氣要先經(jīng)過脫硫裝置。沼氣作為燃氣，其流量調(diào)節(jié)是基于壓力差，為了使調(diào)節(jié)準確，應(yīng)確保進入發(fā)動機時的壓力穩(wěn)定，故需要在沼氣進氣管路上安裝穩(wěn)壓裝置。另外，為了防止進氣管回火引起沼氣管路發(fā)生爆炸，應(yīng)在沼氣供應(yīng)管路上安置防回火與防爆裝置。

1. Methane desulfurization, pressure stabilizing and explosion-proof devices: the biogas contains a small amount of H2S, which has a strong corrosive effect on the engine. Therefore, the biogas used for the engine must first pass through the desulfurization device. As the fuel gas, the flow regulation of biogas is based on the pressure difference. In order to make the regulation accurate, the pressure stability when entering the engine should be ensured, so it is necessary to install a pressure stabilizing device on the biogas inlet pipeline. In addition, in order to prevent explosion of biogas pipeline caused by backfire of intake pipe, anti backfire and explosion-proof devices shall be installed on biogas supply pipeline.

2、進氣系統(tǒng)：在進氣總管上，需加裝一套沼氣-空氣混合器，以調(diào)節(jié)空燃比和混合器進氣量，混合器應(yīng)調(diào)節(jié)靈敏。

2. Intake system: A set of biogas air mixer shall be installed on the intake manifold to adjust the air fuel ratio and the intake volume of the mixer. The mixer shall be sensitive.

3、發(fā)動機：沼氣的燃燒速度很慢，若發(fā)動機內(nèi)的燃燒過程組織不力，會影響發(fā)動機運行壽命，所以對沼氣發(fā)動機有較高的要求。

3. Engine: The combustion speed of biogas is very slow. If the combustion process in the engine is poorly organized, it will affect the operating life of the engine. Therefore, there are high requirements for biogas engines.

4、調(diào)速系統(tǒng)：沼氣發(fā)動機的運行場合是和發(fā)電機一起以用電設(shè)備為負荷進行運轉(zhuǎn)，用電設(shè)備的裝載、卸載會使沼氣發(fā)動機負荷產(chǎn)生波動，為了確保發(fā)電機組正常發(fā)電，沼氣發(fā)電機組的調(diào)速系統(tǒng)必不可少。

4. Speed governing system: the biogas engine operates with the generator under the load of electrical equipment. The loading and unloading of electrical equipment will cause fluctuations in the load of the biogas engine. In order to ensure the normal power generation of the generator set, the speed governing system of the biogas generator set is indispensable.
