six advantages of water tube boiler

Steam Boilers: Classification and Selection | Mechanical

In the fire tube boilers, the hot gases produced after the combustion of fuel pass through the tubes and the water surrounds these tubes. In the water tube boilers, water flows inside tubes and gas remains outside these tubes (Fig. 3.1). A comparison between fire tube and water tube boilers is as follows: Fire Tube Boiler:
