Water Tube Boiler: Construction, Operation - ME Mechanic

Special features of water tube boiler: 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.
