2011/11/8 · In a 100-MW steam turbine at a pressure of about 600 psia (41.4 Bar) and 660 F (350 C), a 1% reduction in steam consumption can cost between $500 000/year and about $900 000/year. This is based on a boiler efficiency of about 85% and lower heating value (LHV) of fuel at 18 900 Btu/lb (10 500 Kcal/kg).
