steam boiler rated evaporation

Boiler Ratings and Boiler Load

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.
