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 33475. This constant represents water being converted to steam which is 34.5 pounds of water multiplied by 970.3 BTU/lb or latent energy. For this calculation you will enter the BTU/hr of your ### Thermodynamic Design of a Fire-Tube Steam Boiler

Boiler Horsepower Calculation - Boiler and Pressure The current equivalency is either 41844 btu/hr heat input or 33475 heat output from burners. Efficiency of the burners is assumed 80%. Now if you have an older fire tube boiler the boiler horsepower is based on heating surface and the equivalency is 1 BoHp= 10 sq.ft. of heating surface. ### calculation of heat transfer on fire tube boiler CFBC ...

boilers may also be referred to as 'fire tube' or 'smoke tube' boilers tubes which in turn transfer heat to the surrounding boiler water. . This factor is calculated by dividing the amount of steam produced per second by the area of the water. ### Boiler Tubes Thickness Pressure Equation and Calculator ...

Solution: For tubing up to and including 5 in O.D. use equation above. P = [580 psi] D = [2.75 in] e = 0 (strength welded) S = [11800 psi] at [650°F]) Note: Where the manufacturing processes produce only standard plate thickness so should be used 1/8 in (3.2 mm) minimum.
