锅炉运行中的排污是非常重要的,其目的是清除炉水浓缩过程中沉积在锅筒和联箱底部的垢渣。排污系统设计安装得正确与否对锅炉运行的安全性经济性影响是很大的。因此《蒸汽锅炉安全监察规程》明确规定:“锅筒、每组水冷壁下集箱的最低处都应装排污阀。蒸发量≥1t/h或工作压力≥7kgf/cm~2锅炉排污管应装两个串联的排污阀”。我们在工作中看到有些锅炉(蒸发量和工作压力均在《蒸汽锅炉安全监察规程》规定的范围内)的排污系统安
It is important that the blowdown be carried out in the operation of the boiler to remove scale deposits deposited on the bottom of the drum and header during the concentration of the boiler water. Sewage system design and installation is correct or not, the safety of boiler operation economy impact is great. Therefore, “steam boiler safety supervision regulations,” clearly states: “drum, the bottom of each set of water wall under the header should be installed sewage valve. Evaporation ≥ 1t / h or working pressure ≥ 7kgf / cm ~ 2 boiler sewage pipe should Install two in series drain valve. ” In our work, we saw that some boilers (both the evaporation and the working pressure are within the limits of the “steam boiler safety supervision code”),
