发电机组的燃气在使用前,应经过预处理(如过滤、气液分离、稳压等)。温度过高时,还应采用冷却器冷却,以保证燃气中没有液态成分。针对不同燃气,处理的流程也不同。
The gas used in the generator set should undergo pre-treatment (such as filtration, gas-liquid separation, pressure stabilization, etc.) before use. When the temperature is too high, a cooler should also be used for cooling to ensure that there are no liquid components in the gas. The processing flow varies for different gases.
若气源压力不足,发电机组虽能正常启动,但可能达不到标定功率。所以用户在选购机组前,应提供气体成分和压力,以便公司提供适宜的产品。下面小编介绍燃气发电机组对7种燃气,在距离机组燃气进气调压阀前1m内的要求。
If the gas source pressure is insufficient, although the generator set can start normally, it may not reach the rated power. So before purchasing a unit, users should provide the gas composition and pressure so that the company can provide suitable products.

友情提示
Friendly Reminder
若可燃气体中含硫或氨成份较高,不仅会严重腐蚀火花塞电极,而且会使机油中酸值增加,腐蚀机组内部零件,同时易于生成沉淀物,增加对发动机的腐蚀和磨损。
If the combustible gas contains high sulfur or ammonia content, it will not only severely corrode the spark plug electrode, but also increase the acid value in the engine oil, corrode the internal parts of the unit, and easily generate sediment, increasing the corrosion and wear of the engine.
