The basic equation for calculating the unloaded steam cost includes the cost of the fuel, operating steam pressure, feedwater Btu, and the boiler efficiency. Here is the equation to calculate an unloaded steam cost: = Steam cost, unloaded = Fuel cost in $/MMBtu = Enthalpy of steam, in Btu/lb. = Enthalpy of boiler feedwater in Btu/lb. = True boiler …Learn More

  • FACILITIES: Steam generation and boilers 101 | Feedstuffs

    Mar 17, 2015 · Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.Learn More

  • KNOWING THE COST OF STEAM

    The outlined steam cost example uses one steam generator (boiler), a single fuel, and one steam pressure. The example of unloaded steam cost calculation uses the deaerator feedwater Btu content, which does not take into consideration make-up water or condensate return. Also, the calculation uses only one boiler efficiency.Learn More
