Estimated direct cost of steam generation

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
