快装锅炉在运行中发生严重缺水后,如立刻向锅内进水,将会使过热的管板孔桥和烟管端部急剧收缩,从而导致板孔扩大,管口缩小,胀口开缝而渗漏。 胀口渗漏后虽可及时补胀,但往往因缺乏有经验的胀接技工和胀管器而耽误时间,从而使胀口产生无法消除的铁锈和污物。发生了这种情况,再采 If there is a serious shortage of water in the operation of a quick-loading boiler, if the water is immediately poured into the pot, the overheated tube-plate hole bridge and the end of the pipe will be drastically contracted, resulting in the enlargement of the plate hole, the reduction of the orifice, the expansion of the orifice Leak and leak. Expansion of the mouth after the leak can be compensated in time, but often due to the lack of experienced expansion joint mechanics and expander delay time, so that the mouth will produce insurmountable rust and dirt. This happens, then mining
