锅炉的排污可降低炉水含盐量,排出泥渣等杂质,高水位时还可紧急降水,根据水质情况每班需要排污数次。但在安装排污管道时往往忽视下面两个问题,导致排污管道易损坏。 一个问题是安装时图省事,将排污支管作成直角,如图1a所示。每次排污时,带压水汽夹杂脏物直接冲击管壁,因冲击点集中,容易造成冲击 Boiler sewage can reduce the salt water furnace, sludge and other impurities discharged at high water level can also be emergency precipitation, according to the water quality needs of each shift several times. However, the installation of sewer pipes often neglects the following two problems, resulting in easily damaged sewer pipes. One of the problems is the installation of a diagram to save time, the sewage branch at right angles, as shown in Figure 1a. Each blowdown, the pressure of water vapor mixed with dirt directly impact the wall, due to the impact point of focus, easily lead to shock
