repair of water tube boiler tubes

Difference Between Smoke Tube And Water Tube Boiler

Smoke tube boilers have water surrounding the tubes. On the other hand, water tube boilers are used in order to generate superheated steam. The functionality of such boilers is totally opposite to that of smoke tube boilers. In water tube boilers, water flows inside the tubes and heat surrounds these tubes. The pressure generated in water tube boilers is higher than the pressure generated in smoke tube boilers.
