Nov 03, 2006 · FACTOR OF EVAPORATION Water enters the boiler at 225°F. The boiler pressure is 100 psi and the boiler water temperature is 338°F. The latent heat is 881 Btu. What is the factor of evaporation? FE = SH + LH / 970.3 FE = SH + LH / 970.3 FE = ((338 - 225) + 881) / 970.3 FE = 1.02 Where, FE factor of evaporation SH sensible heat LH latent heat

Boiler water consumption - Lenntech

The percentage of boiler blowdown is as follows: The blowdown can range from less than 1% when an extremely high-quality feedwater is available to greater than 20% in a critical system with poor-quality feedwater. In plants with sodium zeolite softened makeup water, the percentage is commonly determined by means of a chloride test.

Regardless of cooling tower operating efficiency, approximately 1.8 gallons of water are evaporated for every ton-hour of cooling. Blowdown or bleed-off. is performed to remove high concentrations of dissolved s olids (e.g., calcium, magnesium, chloride, silica) from the cooling tower system.
