Introduction to Condensate Recovery | Spirax Sarco

Steam produced in a boiler by the process of adding heat to the water is often referred to as live steam. The terms live steam and flash steam are only used to differentiate their origin. Whether steam is produced in a boiler or from the natural process of flashing, it has exactly the same potential for giving up heat, and each is used successfully for this purpose.

This efficiency can be calculated using the formula: η= (Energy output)/ (Energy input) X 100. To measure boiler efficiency in this way, we divide the total energy production of a boiler by total energy input provided to the boiler, multiplied by a hundred. Calculation Formula of direct efficiency of boiler-. E= [Q (H-h)/q*GCV]*100.
