Abstract

PURPOSE: To prevent washing liquid from entering a heater by introducing and pressurizing steam or inert gas into the heater when cleaning a boiler.
CONSTITUTION: Washing agent is introducing from an agent tank 7 into a mixing header 9 and a circulating pump 6 is driven to clean an economizer 1 and a boiler 2. At this time a gate valve 10 and a main block valve 11 are closed, and inert gas or steam is introduced from air vents 3b, 4b of the primary superheater 3 and secondary superheater 4 to thereby retain the differential pressure between the gas or steam and the boiler body side at 3kg/cm2.
