Abstract

PURPOSE: To automatically neutralize and wash an economizer, by constituting the economizer such that a spraying device automatically sprays water from a boiler for a predetermined time after a motor stops, when the temperature of an exhaust gas rises.
CONSTITUTION: When the temperature of an exhaust gas rises, the contact TS of thermostat for an exhaust gas is closed. At this time, if the contact F, which is to be closed when a fan motor is stopped, is closed, a fluid controller SV is energized, and then the water of a boiler is sprayed to the inside walls of an economizer from a nozzle of a suction pipe 3 to suck up water to be blown, being provided to the upper part of an economizer 2. At the same time, a timer T is brought into operation, and a contact T1 is opened when a predetermined time has passed, accordingly, a fluid controller SV is closed, and a spray operation is stopped.
