How the process steam consumption scenario calculator works

Usable kWh per kilogram = (steam inlet enthalpy − outlet condensate enthalpy) × transfer-effectiveness fraction ÷ 3,600. Required steam mass equals useful process kWh divided by that positive usable-energy-per-mass value. Zero useful heat gives zero calculated mass.

Enthalpies must use one datum and reviewed states; inlet value must exceed outlet value. Count transfer losses only once. Neither pressure nor steam quality is inferred, and no trap, steam line, boiler, valve or safe process condition is selected. This is a conditional heat-to-mass relation.

Quantities use the stated units and finite bounded inputs. Whole purchases round up under the documented model; cost components round half-up to cents before totals are summed. Undefined ratios stay unavailable. π and logarithms use normal numeric precision. Display rounding does not alter the entered assumptions.

Worked example

An entered 2,800−800 = 2,000 kJ/kg drop at 90% effectiveness gives 0.5 kWh/kg usable heat. A 100 kWh requirement therefore uses 200 kg. A 200 kWh requirement uses 400 kg under the same assumptions.

Sources and assumptions

The source material explains the underlying calculation or pricing structure. Entered prices, costs, schedules and scenario choices are your assumptions; this tool does not obtain supplier quotes or predict actual results.

  • Process Heating Time Scenario

    Net thermal power is entered available output minus the coincident loss input.

  • Steam Energy Cost

    Value a stated steam mass using reviewed steam and feedwater enthalpies, a matching boiler efficiency and an entered fuel rate.

  • Sensible Heat Energy

    Calculate signed ideal heat transfer from mass, an entered specific heat and a temperature change. Keep material energy separate from heater input and losses.

  • Condensate Return Savings Scenario

    Use reviewed return and makeup enthalpies to value a stated return mass, with an explicit makeup-water assumption.
