Our HRSG receive exhaust flue gas from GT at 560 Deg C & exhaust temp from final stack after CPH is 170 Deg C. Steam is generated at a rate of 75 TPH at 37 KG/CM2 and 350 Deg. C. CPH inlet feed water temp is @ 45 Deg.C and outlet temp to deaerator is @ 80 ~ 85 Deg C. How to calculate efficiency of HRSG ?
