Get A QuoteHorsepower (hp) can be converted into lbs of steam by multiplying hp with 34.5. Example - Boiler Horsepower to lbs of Steam Conversion. 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. Example - Lbs of Steam to Boiler Horsepower Conversion. 5000 lbs of steam / 34.5 = 145 hp boiler
Get A Quotebefore it was boiled. So, a boiler which can boil 10,000 pounds of water in one hour is rated at 10,000 pounds per hour. To further confuse the issue, we sometimes speak of Boiler Horse Power (BHP) when we refer to a boilers capacity. One BHP is equal to 34.5 pounds per hour of steam, so 10,000 pounds per hour of steam is the same as 289.9 BHP.
