    锅炉启动过程如何保护过热器和再热器呢?下面小编为您讲解一下:
    How to protect the boiler start-up process of superheater and reheater? Below small make up for you to explain:
    低压阶段因通过受热面的蒸汽流量较少,对管壁的冷却条件较差,主要用控制烟温低于受热面管材的承受温度来保护过热器和再热器;当压力达一定值时,主要通过调节流过过热器和再热器的蒸汽量即开启对空排汽,一,二级旁路,过热器疏水等使其有足够的蒸汽通过以冷却受热面,保护管壁的安全;启动阶段应严格按升温升压曲线和技术标准的有关规定进行升温升压,避免热负荷急剧增加使管壁超温。
    Low-pressure stage due to the heating surface of the steam flow less, on the tube wall of the poor cooling conditions. It is mainly used to smoke temperature control below the heating surface tubes subjected to temperature to protect superheater and reheater; when the pressure reaches a certain value, mainly through regulating the flow through the superheater and reheater steam quantity that is open to air exhaust, secondary bypass, superheater hydrophobic the enough steam through to cool the heating surface, protect the pipe wall; start-up phase should be strict boost curve and technical standards of the relevant provisions according to the warming of temperature and pressure, to avoid the heat load of a sharp increase in the overtemperature of pipe wall.
