マイザの腐食防止装置。 In an economizer that preheats boiler feed water using the heat retained in the boiler waste gas, a feed water preheater that heats with the steam generated by the boiler is installed in the inlet water supply line at the economizer inlet, and the economizer outlet and the boiler are connected via the outlet water supply line. and connect the feed water preheater and the boiler with a steam line, and connect the feed water preheater and the boiler with a hot water line,
A temperature control valve is installed in this hot water line, and this temperature control valve is connected to a temperature sensor installed at the outlet of the water supply preheater in the inlet water supply line to ensure that the inlet water supply temperature is above a certain level. Features a corrosion prevention device for economizers.
