Isobaric Heat Addition by Boiler Calculator






 

 

 


How This Is Calculated


$$ Q_{in} = h_3 - h_2 $$ where:

Qin   =   Heat added in the boiler   (J)

h3   =   Enthalpy of steam exiting the boiler   (J)

h2   =   Enthalpy of the working fluid after the pump (before entering the boiler)   (J)


Assumptions


  • The system is in steady state.
  • Working fluid behaves as an ideal gas.
  • There are no heat losses to surroundings.
  • Specific heats remain constant.
