PURPOSE: A chemical cleaning method of a HRSG(Heat Recovery Steam Generator) is provided to reduce inner damage to a steam generator system in a cleaning process since cleaning processes are individually performed according to a HRSG system. CONSTITUTION: A chemical cleaning method of a HRSG(Heat Recovery Steam Generator, 200) is as follows. A high-pressure system fluid-connected to a high-pressure evaporator(210) is cleaned. A middle-pressure system fluid-connected to a middle-pressure evaporator(220) is cleaned. A low-pressure system fluid-connected to a low-pressure evaporator(230) is cleaned. One or more selected from a group of the kind of cleaner, the concentration of the cleaner, a cleaning time, and a cleaning temperature are different. |
