    如何防止热水锅炉产生汽化?
    来源:澳门在线网站大全 发布时间:2021-09-30

    燃气热水锅炉在运行时,锅内水在循环泵运行不正常和停止期间,如不加注意,很容易引起锅水汽化。轻则使热水循环网路引起“气塞”,重则可能造成锅炉受热面管子烧损或爆管,严重时会引起恶性锅炉爆炸事故。因此,必 须防止热水锅炉产生汽化。
    When the gas-fired hot water boiler is running, the water in the boiler can easily cause the boiler water to vaporize if it is not paid attention to during the abnormal operation and stop of the circulating pump. It may cause "air blockage" in the hot water circulation network, or it may cause burning or pipe explosion of the boiler heating surface, and in serious cases, it may cause malignant boiler explosion accidents. Therefore, vaporization of hot water boilers must be prevented.
    对于燃气热水锅炉内的局部产生汽化,主要是从结构设计来保证,使锅炉的水循环可靠。而对于因突然停泵,停电或整个热水循环系统发生问题造成热水锅炉憋压汽化时,能使已产生的汽不影响热水系统的循环和及时排出蒸汽,通常在锅炉的顶部,节能器上集箱,以及热水管道的高点设置集汽罐。
    The local vaporization in the gas-fired hot water boiler is mainly guaranteed from the structural design to ensure the reliable water circulation of the boiler. When the hot water boiler is pressurized and vaporized due to sudden pump shutdown, power failure or problems in the whole hot water circulation system, the generated steam can not affect the circulation of the hot water system and discharge the steam in time. Usually, the steam collecting tank is set at the top of the boiler, the upper header of the economizer and the high point of the hot water pipeline.
    当突然停泵、停电时,锅炉鼓风,引风机停止了工作,此时,应立即打开炉门,减弱燃烧,降低炉温,同时关闭阀门,再缓慢开启集气管上的排气阀,并可向锅炉内通入冷水,这样,谁就会经热水锅炉和集气罐排出,避免锅水汽化。
    When the pump is suddenly stopped and the power is cut off, the boiler blows and the induced draft fan stops working. At this time, the furnace door should be opened immediately to reduce the combustion and reduce the furnace temperature. At the same time, the valve should be closed, and then the exhaust valve on the gas collector can be opened slowly, and cold water can be introduced into the boiler. In this way, whoever will be discharged through the hot water boiler and gas collector to avoid boiler water vaporization.
    在正常运行时,如果发现锅炉出水温度高于正常温度,或发现压力升高,可能出现了锅水汽化、热水循环系统受阻现象,这时也要通过集气管进行排气。
    During normal operation, if it is found that the outlet water temperature of the boiler is higher than the normal temperature or the pressure increases, the boiler water may vaporize and the hot water circulation system may be blocked. At this time, it is also necessary to exhaust through the gas collector.
