Water-tube boilers tend to be higher rated, perhaps over 1 000 tonnes/h of steam. This means that even a small percentage blowdown can represent a high mass to be blown down. Water-tube boilers tend to operate at higher pressures, usually up to 150 bar g. The higher the pressure, the greater the energy contained in the blowdown water.Get Price
Water tube boilers have the high evaporating capacity (20,000 to 40,000 kg/h) compared with other boilers. The operating pressure lies between 11.5 to 17.5 bar. The draft losses are minimum. The defective tubes in water tube boilers can be identified and replaced easily. The entire boiler rests on iron structures, independent of brick structure.Get Price
Restore power to the controls and fire the boiler. Allow the boiler to fire until the steam pressure or water temperature reaches the setting of the high-limit control. The control should operate at this point and shut down the firing equipment. If the test is okay, disconnect the power and remove the test lead.Get Price
