Boiler Ratings and Boiler Load . The oldest method of rating boilers, still used to rate small boilers, is by horsepower (hp). One horsepower is defined as the ability to evaporate 34.5 lbs of water into steam at 212 deg. F and above. Large boiler capacity is generally given in lbs of steam evaporated per hour, under specified steam conditions.

Chat OnlinePower (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. Remember, we used only 180 BTUs of energy to bring a pound of water to boiling. And we had to add another 970 BTUs to vaporize it to steam. 84.3% of our energy was consumed as the

Chat OnlineThis guidance applies to blowdown arrangements for steam boilers with a maximum evaporative capacity not exceeding 30 tonnes of steam per hour and working pressures not exceeding 32 bar gauge including water tube boilers with a single main blowdown line.
