Abstract
A method of cleaning a boiler of a power generation plant is performed removing an oil component remaining in an interior of the boiler before a steady operation of the power generation plant. For such cleaning, a surface active agent is used as a cleaning liquid, and a cleaning liquid tank, into which the cleaning liquid is stored, is temporarily located, which is connected to a boiler feed water pipe through a cleaning liquid injection pipe and a cleaning liquid injection pump, by which the cleaning liquid is injected into the boiler feed water pipe in a controlled manner to feed the cleaning liquid into the boiler.
