  • Shell Boilers | Spirax Sarco

    For any one boiler, if the heat transfer rate (q_dot - body text.jpg) is increased, the maximum allowable boiler pressure is reduced. A compromise is reached with a furnace tube wall thickness of between 18 mm and 20 mm. This translates to a practical pressure limit for shell boilers of around 27 bar.Learn More

  • Building height and hot water system pressure - Slantfin

    Using the following procedure you can calculate what the fill pressure should be for a given building: Given: Baseboard on top floor of a 6-story building with boiler located in the basement. Each floor is 10 FT. high; therefore the total height to baseboard is 50 FT plus 8 FT for basement = 58 FT. Given: Every 2.3 Ft of water equal 1 PSI.Learn More

  • How to Calculate Boiler Steam Flows | Hunker

    Use boiler horsepower to calculate steam flow. Boiler horsepower is not related to mechanical horsepower. It is a boiler industry rating that predicates the amount of saturated steam a boiler will generate starting with water at 212 degrees Fahrenheit and 0 pounds per square inch gauge (psig--meaning atmospheric pressure) and ending with steam at 212 F and 0 psig.Learn More
