Hi everybody

In our power plant we have waste heat boilers, delivering saturated steam at 7 barg, 170ºC, 3720 kg/h.
The inlet gas flow to the boiler is 30.5 kg/s @386ºC and the outlet gas flow is 30.5 kg/s @311ºC.
The water in the feeder tank is at 90ºC.
I want to know what is the efficiency of such boilers.
Can you help me in this subject please?
