沼氣發電機組在使用中要注意什么?
在進行沼氣發電時,必須控制好沼氣發酵環境,保證發電的效率和質量,因此在使用沼氣發電機組時要注意以下四個方面:
During biogas power generation, the biogas fermentation environment must be controlled to ensure the efficiency and quality of power generation. Therefore, the following four aspects should be paid attention to when using biogas generator set:
剛采購過來的沼氣發電機組,在運行了50個小時建議進行一次常規保養,因為機組的磨合期的保養至關重要,操作人員必須經常檢查沼氣發電機組進氣管路,防止沼氣泄漏和冷凝水過多而影響供氣。
For the newly purchased biogas generator set, it is recommended to carry out a 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.
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。


During the operation of the biogas generator, the operation of the biogas generator unit and the 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.
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。
Air inlet system: during the operation of biogas generator, the operator shall keep abreast of the load changes and limit the maximum load of biogas generator. A set of biogas air mixer shall be installed on the main air inlet pipe to adjust the air-fuel ratio and air intake of mixed gas.
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。
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.
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。
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.
