你好,歡迎來到濟南D88尊龙環能燃氣發電設備有限公司官方網站!

發電機組的使用對于各種媒介使用要求

來源:http://dgxcbw.com   發布于:2019-05-29

發電機組的燃氣在運用前,應經過預處置(如過濾、氣液別離、穩壓等)。溫渡過高時,還應采用冷卻器冷卻,以保證燃氣中沒有液態成分。針對不同燃氣,處置的流程也不同。若氣源壓力缺乏,發電機組雖能正常啟動,但可能達不到標定功率。所以用戶在選購機組前,應提供氣體成分和壓力,以便公司提供適合的產品。下面小編引見燃氣發電機組對燃氣,在間隔機組燃氣進氣調壓閥前1m內的請求。

Gas of generating units should be pre-disposed before operation (such as filtration, gas-liquid separation, voltage stabilization, etc.). When the temperature is too high, the cooler should be used to cool the gas to ensure that there is no liquid component in the gas. For different gas, the disposal process is also different. If the gas pressure is insufficient, the generator set can start normally, but it may not reach the calibration power. Therefore, before purchasing units, users should provide gas composition and pressure, so that the company can provide suitable products. The following section introduces the request for gas from gas generating units within 1 m before the gas intake pressure regulating valve of spacer units.
