Evaporation of liquid (other than water)

GZ: kg / hour

A: Ash of coal, %

M: liquid molecular weight

V: The air flow rate (m/s) on the surface of the evaporating liquid, based on the measured data, unconditionally measured, generally 0.2-0.5)

P: corresponding to the partial pressure of steam in the air at a liquid temperature (mmHg), when the liquid concentration is less than 10%, replaced by the saturated vapor pressure of the aqueous solution; when the liquid concentration is higher than 10%

F: Surface area of the liquid evaporation surface.
