This equipment heats feed water by turbine bleed to improve the thermal efficiency of a steam turbine plant.
Heating the water supply saves the amount of heat required to boil the steam.

As with the low-pressure feed water heater, this equipment heats the feed water by turbine bleed to improve the thermal efficiency of the steam turbine plant. The feed water pressure is higher than that of the low-pressure feed water heater.

Oxygen is contained in the water supply, and when the oxygen is combined with iron, it oxidizes and causes corrosion and thinning.
This equipment aims to heat boiler feed water and remove dissolved oxygen in feed water by directly mixing turbine bleed air and boiler feed water.

Equipment to generate flash steam and separate from the drain for recovering heat from generated steam, by flowing blow water discharged from the boiler into the vessel and depressurizing it.

This equipment uses low-pressure or high-pressure steam to heat the combustion air to a specified temperature in order to improve the boiler combustion efficiency.

This equipment is used to reheat boiler exhaust gas with steam to a predetermined temperature, and to prevent corrosion of the exhaust gas flue on the wake side.
