热水锅炉受火锅筒直接受火焰辐射热,一但过热,就会发生变形鼓包事故,影响安全生产。 一、受火锅筒产生鼓包的原因 KZ型和SZS型两种锅筒直接受火的蒸汽锅炉,很多被改装成热水锅炉。在KZ型锅炉中(见图一),左右联箱一侧改为热水锅炉之进口,原主汽阀处为热水出口,原排污系统未改动, Hot water boilers by the pot directly by the flame radiant heat, but overheating, deformation drum accident will occur, affecting safety in production. First, the drum drum produced by the drum reason KZ-type and SZS-type two drum directly by the steam boiler, many are converted into hot water boiler.
