Factors Of Evaporation Example.-Suppose that a cylinder boiler is to be proportioned for an evaporation of 500 lbs. of water per hour, at a pressure of 75 lbs., the temperature of the feed-water being 80°. The equivalent evaporation will be 1.17 times 500, or 585 lbs., and the grate-surface 585 divided by 75, or 7-8/10 square feet.

Jun 23, 2017 · Equivalent evaporation actually indicates the amount of heat added in the boiler for steam generation. Equivalent evaporation refers to the quantity of dry saturated steam generated per unit of time from feedwater at 100°C to steam at 100°C at the saturation pressure corresponding to 100°C. Sometimes it is called equivalent evaporation from and at 100°C. Thus mathematically it could be given as: For a boiler generating steam …
