Therefore stack losses are currently 4,674,000 Btu/hr.
Note: If an EGA is optioned, then the stack losses are taken from the EGA data rather than default
system values for greater accuracy.

Therefore the net calorific value of the fuel (wet) is 19,434,000 Btu/hr.
The boiler efficiency is determined by:
