Hi,
Can anyone show increase in boiler efficiency using the direct method (output/input) when installing an economizer?
Lets say feedwater temp is without an economizer is around 32C. Installing an economizer would increase it to 50 C (just numbers)
and saturated steam temp is 190 C.
When applying the enthalpy on the output part of the equation and considering the input is constant, I cannot see the increase in efficiency or maybe there is some missing information.
Thanks
