降低锅炉“四管”泄漏次数的方法综述

火力发电厂中,锅炉"四管"的安全稳定运行,直接与发电机组的安全稳定经济运行联系在一起,一旦发生"四管"泄漏,机组就得被迫停运,进行抢修,严重影响电厂的安全经济运行。针对国产300MW、600MW火力发电机组锅炉"四管"泄漏问题,近几年来,通过对洛河电厂6台锅炉"四管"存在的问题及"四管"泄漏情况的分析,找出"四管"泄漏的原因并采取了相应的措施,使洛河电厂在"四管"治理上积累了一定经验,同时降低了"四管"的泄漏次数。

In thermal power plant, boiler ＂four-barrel＂ the security stable movement, with power set Ts security stable economy movement relates directly in together, once has ＂the four-barrel＂ divulging, the unit is compelled to suspend shipment, carries on the emergency repair, affects the power plant seriously the security economy movement. In view of domestically produced 300MW, the 600MW thermoelectricity generation unit boiler ＂the four- barrel＂ the divulging question, in the last few years, through to the Luohe river power plant 6 boilers ＂the four-barrel＂ the existence question and ＂the four-barrel＂ the divulging situation analysis, discovered ＂the four-barrel＂ the divulging reason and has taken the corresponding measure, made the Luohe river power plant in the government to accumulate certain experience in ＂the four-barrel＂ , simultaneously reduced ＂the four--barrel＂ divulging number of times,
