1锅炉系统防漏风锅炉系统外漏风的地方一般都出现在膨胀节处。对于膨胀节本体,由于烟气温度过高和粉尘过多造成的漏风,一般是对膨胀节及时修补和更换。膨胀节法兰与管道法兰连接处一般采用无尘石棉绳进行密封,长时间运行由于高温烟气的冲刷,石棉绳极易灰化造成连接处漏风。对此我们采取的措施是对该连接处进行密封焊接,确保法兰连接处无漏风。 A boiler system leak-proof boiler system outside the air leakage generally appear in the expansion joints. For the expansion joint body, as the flue gas temperature is too high and dust caused by excessive air leakage, the expansion joint is generally timely repair and replacement. Expansion joints and pipe flange flanges generally used asbestos dust-free clean sealed, long-term operation due to the erosion of high-temperature flue gas, asbestos rope easily lead to air leakage at the junction. In this regard, we take measures to seal the joints sealed to ensure that the flange connection without air leakage.
