Total Heat of Steam = Sensible Heat + Latent Heat of Vaporisation Specific Enthalpy : Steam = Water + Evaporation Thus the Total Heat of Steam (Specific Enthalpy - Steam) is 2,676 kJ/kg (1151 Btu/lb) This data is found in Steam Tables. Steam.
The cost to operate the central boiler at 30 bhp is 1.338 mcf/hr x $7.00/mcf = $9.37/hr. Piping losses are ignored since the boiler has plenty of excess capacity to overcome these losses at the minimum turndown ratio. For oil fired boilers, the situation is similar — fuel prices vary by locale and supplier, and are prone to future increases.
This chart is used to calculate the percent of boiler water discharged by a continuous blowdown system that can be flashed into steam at a reduced pressure and is recoverable as low pressure steam for heating or process.
Boiler Energy = Steam Energy Flow + Blowdown Energy Flow - Feedwater Energy Flow [ Boiler Energy (Flow) = 62,904 = 73,045 + 274 - 10,416 ] Step 5: Determine Fuel Energy

Online calculator to quickly determine Steam Unit Cost. Includes 53 different calculations. Equations displayed for easy reference.
2017-5-5 · of steam is to calculate the unloaded steam cost, which only requires reviewing the boiler operation (steam Btu, feedwater Btu, boiler efficiency, and fuel cost). The loaded steam cost takes into account all aspects and costs of producing steam, which provides a more accurate steam cost. 1.2.1.

Steam Consumption Calculation. The following table is prepared to calculate the steam consumption of various processes and accordingly to help determine the boiler type, boiler operating pressure and boiler capacity. However, if the manufacturer of steam-using equipment has specified the amount of steam pressure and steam consumption for their
Step 4: Determine Boiler Energy Boiler Energy = Steam Energy Flow + Blowdown Energy Flow - Feedwater Energy Flow [ Boiler Energy (Flow) = 59,706 = 73,675 + 2,107 - 16,077 ] Step 5: Determine Fuel Energy Fuel Energy = Boiler Energy / [ =
S = Amount of solids (ppm) B = Blow down (m3 / hr) C = Maximum permissible concentration of solid inside the boiler drum. B = E x S (m3 / hr.)/(C–S) % B = S/(C–S) This formula has been equally applied to control individual constituents in boiler. Blow down means, "lost heat".
Here is the equation to calculate unloaded steam cost: Where: • S C = steam cost, unloaded • a F = fuel cost in $/MMBtu • H g = enthalpy of steam, in Btu/lb. • h f = enthalpy of boiler feedwater in Btu/lb. • η B = true boiler efficiency (ASME PTC 4.1) • 1,000 = steam
In addition we have provide other programs to determine Boiler Operating Cost, based on Steam losses, which might be happening in your system. These Thermal Calculations are a useful tool. Our intentions are to make you aware of the high cost associated with not maintaining your equipment or providing a payback cost to replace your present equipment with more efficient equipment technology.
