Stem Generation

05/10/2012 9:20 AM

Dear Sir,

I have flue gas flow of 33000Nm³/hr @ temp of 600°C & pressure 0.245barg.

I want to generatae steam by utilising the heat of gas ,how much saturated steam of 17.5Kg/Cm2g will be generated by maintaining gas outlet temp 320°C.

Please provide the calculation.

Regards

Missing:

  • the specific heat of the flue gas
  • the temperature of the steam
  • the quality of the steam
  • the efficiency of the boiler/economiser

What is wanted is a round estimate of this number, surely? The flue gas temperature and flow will vary, and so will the steam. A round estimate will give sufficient information to estabilsh whether it is worth doing economically.

  • the specific heat of the flue gas :0.36kcal/kg°c
  • the temperature of the steam : 208
  • the quality of the steam :Dry Saturated /SuperHeated
  • the efficiency of the boiler/economiser : 85%

Please let me know how much steam will generate in boier
