steam boiler Agent drop header - elektrische-woche.de

Because water acts as a cooling agent inside boilers, low water levels inside the boiler cause the pressure in the boiler to rise. The water absorbs heat created through combustion and turns it into steam. As the amount of water in the steam drum within the boiler decreases, the amount of heat absorbed by the water decreases, thus heating the

Heat Recovery from Boiler Blowdown TDS Control …

Heat recovery using heat exchangers. Heat recovery from residual blowdown. About 40% of the energy in boiler blowdown can be recovered through the use of a flash vessel and associated equipment; however, there is scope for further heat recovery from the residual blowdown itself.
