目前,在小型蒸汽锅炉安装中,常碰到一些值得引起重视的问题,主要的有:1.可分式省煤器上的再循环管,有一种错误的接法,就是将省煤器出口处,接一旁路,直通排污总管,理由是,升火停炉时,锅炉不需或进水量很小时,打开旁路上的排污阀,将省煤器热水排掉,再向省煤器进给常温水,这样,如果给水小于排水,或者只注意排水降温,不注意给水,省煤器就会缺水过热、烧环。同时,将省煤器中的热水大量排走,也是 At present, the installation of small steam boilers often encounter some issues worthy of attention, the main are: 1. Recoverable separator on the economizer, there is a wrong connection, is to economizer exit Department, take a bypass, through the sewage Explorer, the reason is that when the fire off the stove, the boiler does not need or when the amount of water is very small, open the bypass on the drain valve, the economizer drain, and then into the economizer To the water at room temperature, so that if the water supply is less than drainage, or only pay attention to drainage cooling, do not pay attention to water, economizer will lack of water overheating, burning ring. At the same time, a large number of hot water economizer drain away, too
