This tutorial explains the three most commonly used boiler ratings: The 'From and at' rating for evaporation, the kW rating for heat output, and boiler horsepower. 'From and at' rating The ‘from and at’ rating is widely used as a datum by shell boiler manufacturers to give a boiler a rating which shows the amount of steam in kg/h which the
View MoreA boilers capacity is usually expressed as kBtu/hour (1000 Btu/hour) and can be calculated as. W = (h g - h f) m (1) where . W = boiler capacity (Btu/h, kW) h g = enthalpy steam (Btu/lb, kJ/kg) h f = enthalpy condensate (Btu/lb, kJ/kg) m = steam evaporated (lb/h, kg/s) Boiler Horsepower - BHP. The Boiler Horsepower (BHP) is

View MoreBoiler 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.
View More33.475 BTU / hr (9,811 kilowatts) to generate 1 hp. Unfortunately, the common practice is to use the conversion factor of 34.5 lb / hr hp to calculate the boiler generated steam rate without considering that the boiler does not work at atmospheric pressure. ex. 500 hp x 34.5 lb / hp hr = 17,250 lb / hr produced by the boiler.
View MoreHow to convert boiler horsepower to kilowatts [BHP to kW]: P kW = 9.81055407 × P BHP. How many kilowatts in a boiler horsepower: If P BHP = 1 then P kW = 9.81055407 × 1 = 9.81055407 kW. How many kilowatts in 5 boiler horsepower: If P BHP = 5 then P kW = 9.81055407 × 5 = 49.05277035 kW
View MoreBoiler horsepower - a power unit from the 19 th-20 th centuries - was used to rate the capacity of a boiler to deliver steam to steam engines.. 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 212 o F (100 o C) - with feed water at pressure 0 psig and …

View MoreJun 18, 2014· When you look in a boiler manufacturer's catalog you'll see that there are several types of ratings for each boiler. There's the Input rating, the Gross Output rating (which some call the D.O.E. Heating Capacity) and then there's the Net Output rating.
View MoreAug 16, 2017· Next up will be the Steady State Efficiency. This is estimated by dividing the Heating Capacity by the Fuel Input Rating (Btu/h). For example, if we have a natural gas boiler with an input rating of 100,000 Btu/h and a heating capacity of 85,000, we would have a steady state efficiency of 85 per cent.

View MoreComparing the efficiency of electric, gas and oil boilers side-by-side can be challenging because despite being 99-100% efficient, electric boilers tend to have an ErP rating of D. On the other hand, all condensing gas and oil boilers must reach a minimum efficiency level of 92%, yet this is enough to award them an ErP A-rating.
