BOILER HORSEPOWER EXPLAINED

Prior to 1876 Boiler Horsepower was based upon the heating area of a boiler with every 10 square foot of heating surface equaling 1 boiler horsepower. This would mean that a boiler with 200 square feet of heating surface would be rated at 20 boiler horsepower. Not a very exact way to measure the output of a boiler to say the least, especially given the different designs and efficiencies of boilers available.

All this changed at the 1876 Centennial Exhibition held in Philadelphia, PA. There judges decided to use “developed horsepower” which they defined as the ability to turn 30 pounds of 100 degree F feedwater per hour into steam at 70 psi. In 1884, ASME defined Boiler Horsepower as the amount of power required to convert 34.5 pounds of water per hour from feedwater at 212 degree F to dry, saturated steam at the same temperature. Today 1 boiler horsepower is equal to 33,475 Btu/Hour which is the amount of energy required to evaporate 34.5 pounds of water at 212 degree F in one hour.

What is an Industrial Boiler?

An industrial boiler is a specialized type of equipment used to generate steam or hot water for industrial processes or heating purposes. These boilers are typically larger and more robust than residential boilers, designed to handle higher pressures and temperatures, as well as varying types of fuels.

Key characteristics and uses of industrial boilers include:

Steam Generation –  Industrial boilers are primarily used to produce steam, which is widely used in industrial processes such as manufacturing, power generation, food processing, chemical processing, and others. Steam is used for heating, drying, sterilizing, and mechanical power generation in various industries.

Hot Water Production – Some industrial boilers are also used to produce hot water for heating applications in large buildings, hospitals, schools, and other facilities where a centralized heating system is required.

Natural Gas for Our Future
Natural Gas an ideal fuel source for many reasons, including safety. Natural Gas is lighter than air. This means that it will not puddle (like gasoline) or sink to the ground like propane, which is heavier than air. Instead, Natural Gas will rise and dissipate in the atmosphere. Natural gas also has a higher ignition temperature. This means that it is much harder to ignite. Also the storage systems used for compressed natural gas are infinitely stronger that the gasoline tanks found on cars and trucks today.
