  • EFFECT ON START-UP COST BY USING BOILER

    Such a phenomena will happen in super critical once through boiler. But up to achieve that state feed water Circulation is required in boiler. The feed water coming from BFP Through all Heaters, Economiser and Water wall tubes will gain heat and starts steaming which will be separated in Boiler Separator and flows to Super heater cools.
