How much natural gas is required for 1 ton of steam?

Approximately 77 Sm³ at 10 bar(g) steam, 80 °C feed water and 92% efficiency. This amount decreases as the feed water temperature increases (e.g. with condensate return).

How can I reduce the steam cost?

Increasing the condensate return, using an economizer, eliminating trap leaks and insulating the lines are the most effective methods. Solid fuel boilers with low fuel costs also provide significant savings.

Steam Cost Calculation – How Much TL is 1 Ton of Steam?

Steam cost is a basic indicator that every steam-consuming business should know: only with it can you calculate the cost of leaking steam traps, uninsulated lines and condensate losses. This tool calculates the fuel cost of 1 ton of steam and the amount of fuel required

Formula

Steam cost (1 t) = Ce × (hg − hfw)
Ce = Fuel price ÷ (Hu × η)

Ce: cost of 1 MJ useful energy, hg: steam enthalpy, hfw: feed water enthalpy (kJ/kg = MJ/t).

Example

Approximately 77.0 Sm³ natural gas is required for 10 bar (g) steam, 80 °C feed water and 1 ton of steam in a 92% efficient natural gas boiler. For example, if the price of natural gas is taken as 10 ₺/Sm³, the fuel cost of 1 ton of steam is approximately 770 ₺.

This value is fuel cost only; water treatment, electricity, maintenance and personnel expenses are not included.
