When your size you might notice two powers in the specifications of a given One is the power the other is power says how much energy goes into the to make it work and says how much of that energy is converted into usable heat Efficiency is the percentage of from the inputGet a Quote
Each is given a horsepower (BHP) rating based on the capacity at 212°F and 0 psig For this calculation you will enter the load in pounds per hour which will be divided by a constant of 345 This number represents the thermal energy rate required to turn 345 lbs of water at 212 °F to in one hourGet a Quote
heat How to Heat Input Rate | Sciencing The factor relating these rates is the specific heat capacity of water Subtract the water's initial temperature from its temperature at the end of the period whose input rate you are calculatingGet a Quote
The Boiler Horsepower (BHP) is the amount of energy required to produce 345 pounds of steam per hour at a pressure and temperature of 0 Psig and 212 oF with feedwater at 0 Psig and 212 oF A BHP is equivalent to 33475 BTU/Hr or 8430 Kcal/Hr and it should be noted that a boiler horsepower is 131547 times a normal horsepowerGet a Quote
· Using the Property properties are determined using Steam Pressure and the selected second parameter (Temperature Specific Enthalpy Specific Entropy or Quality) The Specific Enthalpy is then multiplied by the Mass Flow to get the Energy Flow: Energy Flow = Specific Enthalpy * Mass FlowGet a Quote
It is common to express the of fire tube and water tube in Horsepower MBTU or in Pounds of delivered per hour W = (hg - hf) m where W = capacity (Btu/h) hg = enthalpy (Btu/lb) hf = enthalpy condensate (Btu/lb) m = evaporated (lb/h) Calculate the capacity for example:Get a Quote
