How To Calculate The Cost of Steam Boiler?

Overall boiler efficiency becomes primarily a function of the final flue gas temperature, and will typically be in the range of 80 to 85% when the excess air ratios are near optimal. The second step is to calculate the cost of steam at lower pressure levels.
