Read MoreTo 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, or latent energy. For this calculation, you will enter the BTU/hr of your operation along with the efficiency of your boiler.

Read MoreBOILER TYPES FOR STEAM APPLICATIONS This article covers the basic difference between common boiler types for high pressure steam applications in the capacity range of 5,000,000 to 100,000,000 Btu/hr (5-100 MMBTU/hr or 120 - 2400 HP). This size range would be the larger commercial, institutional and industrial applications.

Read MoreThe 'from and at' rating is widely used as a datum by shell boiler manufacturers to give a boiler a rating which shows the amount of steam in kg/h which the boiler can create 'from and at 100°C',at atmospheric pressure. Each kilogram of steam would then have received 2 257 kJ of heat from the boiler. Shell boilers are often operated

They let the factor for steam boiler sizing remain at 1.33 because steam piping is bigger than hot water piping. This is because steam is bigger than water. There's one problem here, though. Steam pipes contain hardly any water.
