1. For the newly purchased biogas generator set, it is recommended to carry out routine maintenance after 50 hours of operation, because the maintenance of the unit during the running in period is very important. The operator must often check the air inlet pipeline of the biogas generator set to prevent biogas leakage and too much condensate from affecting the gas supply.

2、沼氣發電機工作時應經常巡視、檢查沼氣發電機組的運行情況，沼氣脫硫及穩壓、防爆裝置，另外，為了防止進氣管回火引起沼氣管路發生爆炸，應在沼氣供應管路上安置防回火與防爆裝置，發現問題應及時調整或上報有關領導。

2. During the operation of the biogas generator, the operation of the biogas generator unit, biogas desulfurization, pressure stabilization and explosion-proof devices shall be inspected frequently. In addition, in order to prevent the explosion of the biogas pipeline caused by the tempering of the air inlet pipe, the anti tempering and explosion-proof devices shall be installed on the biogas supply pipeline, and the problems found shall be adjusted or reported to the relevant leaders in time.

3、進氣系統：沼氣發電機在運行中，操作人員應隨時掌握負載變化情況并應對沼氣發電機的負荷進行限制，在進氣總管上，需加裝一套沼氣一空氣混合器，以調節空燃比和混合氣進氣量。

3. Air intake system: when the biogas generator is in operation, the operator shall keep abreast of the load changes and limit the maximum load of the biogas generator. A set of biogas air mixer shall be installed on the main air intake pipe to adjust the air-fuel ratio and air intake of the mixture.

4、發動機：沼氣的燃燒速度很慢，所以對沼氣發動機有較高的要求。沼氣發電機的過濾裝置應定期清洗。

4. Engine: the combustion speed of biogas is very slow, so there are high requirements for biogas engine. The filter device of biogas generator shall be cleaned regularly.

5、調速系統：沼氣發電機組沼氣進氣壓力不得低于1.8kPa，沼氣發動機的運行場合是和發電機一起以用電設備為負荷進行運轉，為了確保發電機正常發電，沼氣發動機上的調速系統必不可少。

5. Speed regulation system: the biogas inlet pressure of biogas generator set shall not be less than 1.8kpa. The operation occasion of biogas engine is to operate with the generator under the load of electrical equipment. In order to ensure the normal power generation of generator, the speed regulation system on biogas engine is essential.
