Oct 02, 2017 · Calculation of boiler Heat Duty Using desired steam parameters, calculate the enthalpy of steam to be generated Multiplying enthalpy with the rated steam generation, obtain the …

### Boiler – Fundamentals and Best Practices

Total Heat of Steam = Sensible Heat + Latent Heat of Vaporisation Specific Enthalpy : Steam = Water + Evaporation Thus the Total Heat of Steam (Specific Enthalpy - Steam) is 2,676 kJ/kg (1151 Btu/lb) This data is found in Steam Tables. Steam.

The BTU/hour to Boiler Horsepower calculator is used to help size both steam and hot water boilers. This calculation translates the heat transfer input requirement to BHP. To do so, we divide the BTU/hour by a constant of 33,475. This constant represents water being converted to steam, which is 34.5 pounds of water multiplied by 970.3 BTU/lb, or latent energy. For this calculation, you will enter the BTU/hr of your operation along with the efficiency of your boiler.

### What is Boiler Efficiency? Boiler Efficiency Calculation

App 1-7 HHV is the higher heating value, hg is the enthalpy in Btu/lb of water vapour at 1 psi and the flue gas temperature (FGT) in °F, and hf is the enthalpy of water at the combustion air temperature (CAT) in °F. hg can be determined from steam tables or from the equation hg, Btu/lb = 1055 + (0.467 x FGT). hf can also be determined from steam tables, or from the simple relationship

The total pressure loss of the superheater stages should be chosen. Thus, the pressure in steam drum (drum-type boilers) or pressure after evaporator (once-through boilers) can be calculated by adding the pressure loss over the superheater stages to the pressure of the superheated steam. 3.
