Abstract

PURPOSE: To perform a cleaning of a preheater pipe as well as to neutralize a surface of the preheater pipe and prevent a corrosion thereof by a method wherein a water feeding preheater pipe is arranged in a chimney base and a boiler blowing water is injected from above the water feeding preheater unit so as to clean the preheater pipe.
CONSTITUTION: Blowing valve is opened for a boiler water feeding preheater pipe 6 and the blowing water is injected from the blowing water injection outlet port 9. Thereby, soot adhered to the surface of the preheating pipe 6 is cleaned off and a heat conducting surface is neutralized due to alkaline characteristic of blowing water. They are discharged into a water storage tank (not shown) from a discharging pipe 11. In this way, cleaning of the preheating pipe 6 as well as the neutralization of surface thereof are performed so as to prevent a corrosion of the pipe.
