Since these types of boilers have different usages, there are certain inputs that matter more when estimating the size of your boiler. Boiler horsepower is used for sizing steam boilers. Lbs of steam can be converted to hp by dividing lbs steam per hour by 34.5. For this calculation, you will enter the steam load in pounds per hour, which will be divided by a constant of 34.5. Example - Lbs of Steam to Boiler Horsepower Conversion A steam boiler is used to meet your high or low pressure steam system requirements while a hot water boiler is typically used to provide hydronic heat. We don't collect information from our users. If you feel any hesitation, please contact with our consumer service online. Meanwhile, Specific Heat (SH), Specific Gravity (SG) and Density of the medium being circulated are important properties to include to ensure proper sizing. While not as common, undersized boilers can also lead to production issues. AddThis use cookies for handling links to social media. Only emails and answers are saved in our archive. All our rental boilers are completely portable and can be on your site within hours. 200 hp x 34.5 = 6900 lbs of steam per hour, Lbs of steam can be converted to hp by dividing lbs steam per hour by 34.5. Click on the Icon above will initiate Heat Converter, Pressure Converter, Temperature Converter. We’ve given you the frameworks to help estimate the size of your boiler. Contact us and we’ll walk you through the following questions so we can make sure you find the right boiler for your operation. We’ve created three custom calculators to help you size an industrial boiler, including. Btus Per Hour to Boiler Horsepower (or just enter a value in the "to" field) Please share if you found this tool useful: Tweet. Click on the Icon above will initiate Heat Converter, Pressure Converter, Temperature Converter. Density of a substance refers to its mass per unit volume. Boiler load - the capacity of a steam boiler - is often rated as boiler horse powers, lbs of steam delivered per hour, or BTU. Example - Boiler Horsepower to lbs of Steam Conversion This calculation translates the heat transfer input requirement to BHP. Instead, the flow of water and required temperature change, which directly corresponds to the difference in sensible heat, are the main drivers for the BTU/hr load of the system. We have brand new boilers in stock and for sale as well as reconditioned used boilers that we can ship to your facility today. A BTU, or a British Thermal Unit, is a unit of heat defined as the amount of heat required to raise the temperature of a single pound of water by 1 °F. A common definition of one boiler horsepower is the amount of energy required to produce 34.5 pounds (15.65 kg) of steam per hour at pressure and temperature 0 psig (0 bar) and 212oF (100oC) - with feed water at pressure 0 psig and temperature 212oF. When comparing materials of the same size (volume) those with a higher density will have a larger mass (be heavier) than those with a lower density. Boiler Horsepower is defined as the thermal energy rate required to turn 34.5 lbs of water at 212 °F to steam in one hour. Using our industrial boiler sizing guide, you’ll be able to understand: Taking the time to properly size your boiler helps to make sure you have a reliable and efficient operation. This is because neither the output requirement nor boiler horsepower take the boiler efficiency into account - they are both a measurement of boiler output capacity only. This calculation translates the steam load (in pounds per hour) to boiler horsepower. Boiler Horsepower: BHP = (LB/HR*fe)/34.5: Lb/Hr: Pounds per Hour: BHP = 21500 * 1.08 / 34.5: Fe: Factor of Evaporation: BHP = 673 Engineering ToolBox - Resources, Tools and Basic Information for Engineering and Design of Technical Applications! © 2020 Powerhouse Equipment & Engineering Co.

This just means that the total load is split between N number of boilers and an additional boiler sits idle for availability if a main boiler was to go out of service (due to failure, safety device tripping, or maintenance). Since there are no phase changes, the latent energy is not utilized in hot water boilers. Example - Boiler Horsepower to lbs of Steam Conversion More often than not, businesses operate with oversized boilers, which causes issues with boiler efficiency. To do so, we divide the BTU/hour by a constant of 33,475. Horsepower (hp) can be converted into lbs of steam by multiplying hp with 34.5. GPM is a measurement of volumetric flow measuring the number of gallons to flow past a point of reference every minute. Since a boiler horsepower is a measurement of energy required to convert the water to steam, we need to account for the difference between the heat input of the fuel and the efficiency of the boiler to transfer that energy to the water in order to produce steam.

Some of our calculators and applications let you save application data to your local computer. Google use cookies for serving our ads and handling visitor statistics. With the Specific Heat, Specific Gravity and Density values representing the properties of water, the output of this calculation will tell you the BTU. Typically, in industrial boiler applications, the fuel-to-steam efficiency is between 80-85%. Converted LB into HP 5000 lbs of steam / 34.5 = 145 hp boiler. Each boiler is given a boiler horsepower (BHP) rating based on the steam output capacity at 212°F and 0 psig. Typically, in boilers, this is referring to the difference between the supply and return temperatures. A boilers capacity is usually expressed as kBtu/hour (1000 Btu/hour) and can be calculated as, W = (hg - hf) m                                         (1). Delta is a Greek letter that is used in Mathematics and Engineering to denote a change in a value. Delta T (ΔT) identifies the change in temperature between two points. One boiler horsepower is about 33479 Btu per hour (about 9812 watts, 8437 kcal/hr).
