1. Water tube. 2. Fire tube. In water tube boilers, water circulates through the tubes and hot products of combustion flow over these tubes. In fire tube boiler the hot products of combustion pass through the tubes, which are surrounded, by water. Fire tube boilers have low initial cost, and are more compacts. But

Boiler – Fundamentals and Best Practices

The BTU/hour to Boiler Horsepower calculator is used to help size both steam and hot water boilers. This calculation translates the heat transfer input requirement to BHP. To do so, we divide the BTU/hour by a constant of 33,475. This constant represents water being converted to steam, which is 34.5 pounds of water multiplied by 970.3 BTU/lb

Mar 12, 2012 · Fire tube boilers are large-volume boilers. A large vessel, filled with water, is pierced with tubes of various sizes. Radiative heat transfer occurs mainly in the fire tube at the bottom. Convective heat transfer takes place in the large number of parallel gas tubes in the top. Hot flue gas transfers heat through tubes to the water.
