        Boiler Design: Composition, Benefits, & How to Start

        Water-tube design boilers are quite fit for applications needing large amounts of steam, such as industrial process purposes, and are used less often for heating purposes. The benefits of the water-tube steam boiler design include the following: Accessible in sizes far greater than a fire-tube boiler design, up to some million pounds per hour

        Proper sizing of Boiler Feedwater System

        To calculate the storage tank needed use the following formula: BHP X 34.5 ÷ 8.337 lbs ÷ 60 min. X 10 = minimum useable capacity in gallons. For example, if you have a 500 HP boiler the calculation will be as follows –. 500 x 34.5 ÷ 8.337 ÷ 60 X 10 = 345 gallons.
