Abstract
PURPOSE: To protect the iron of the feed water heaters and drain pipes of thermal power plant or the like from corrosion, by introducing a feed water treating agent such as ammonia from the heated steam pipes and drain pipes of te heaters and the heaters themselves.
CONSTITUTION: The feed water treating agent, introduced into a high-pressure feed water heated steam pipe 14A from a pump 20 through a pipe 21, flows into the main body container 27 of a feed water heatr 11 and is then mixed with the drain of the heater. The mixture flows into a low-pressure feed water heater 10, through a drain pipe 15A. At that time, the treating agent introduced into the drain pipe 15A flows into the heater 10, too. Since the treating agent introduced into the high pressure steam pipes 14AW14D and the high-pressure feed water heater drain pipes 15A W15C flows to the low-pressure feed water heaters 8W11 sequentially, the iron on the inside surfaces of the drain pipes 15AW15C and the main body containers 27 of the heaters 8W11 is protected fom being eroded by steam etc
