  • Process for feed-water oxygenating treatment in boiler in power station
    Patent number: 9714179
    Abstract: The present invention provides a process of oxygenated feed-water treatment of boilers in power station, carried out under an OT treatment process, suitable for both the monotube type boiler and the drum type boiler, and comprising an oxygenation stage comprising: a normal oxygenation converting stage and a decreased oxygenation film-supplementing stage; the normal oxygenation converting stage is a stage in which the feed water system is oxygenated both at the outlet of a condensate polishing system and at the inlet of a feed water pump of a high pressure feed water system, and the concentration of dissolved oxygen in the main steam is controlled to be ?5 ?g/L; the decreased oxygenation film-supplementing stage is a stage in which, after an oxide film is formed in the feed water system, the amount of oxygenation at the high pressure feed water system is decreased so that the amount of the oxygen added is only for supplementing and maintaining the oxide film, while the concentration of dissolved oxygen in the
