How can we calculate the efficiency of a boiler of a thermal

For a boiler, Energy output = Steam flow rate X (Steam outlet enthalpy - feed water enthalpy) - (blowdown mass flow rate and blowdown enthalpy) and, Energy input = Mass flow rate of fuel X GCV of fuel. Use of steam turbines and condensers in a thermal power plant does not affect efficiency calculation of a boiler.

This isn't about heat loss. This is about heating a LOT of metal. So . . . is the boiler a cold-start boiler (which means you have metal to heat every time it starts), or is the boiler operating on outdoor reset (where there would be less of a temperature rise each time). All of this changes depending on how cold it is outside, of course.
