Notes:
Assumes that steam generated has dryness fraction of 97%, saturated steam
Boiler blowdown may include; tds and bottom blowdown
Typical calorific values for the fuel are used. These may vary
Actual figures may vary depending on condensate return rates, flash steam recovery, and any other similar equipment. Labour and maintenance costs are not included
Figures calculated are of a simple theoretical nature and other variables may need to be considered depending on application
