Abstract:
A method of converting a liquid flow into a gas flow in a heated evaporation cavity, comprising the following method steps:supplying the liquid flow towards said evaporation cavity;dispersing the liquid flow by means of ultrasonic waves so as to enlarge the surface of the liquid, said dispersion being not caused by change of pressure, but by subjecting the liquid to a mechanical vibration, and taking place without any admixture of a medium;introducing said dispersed liquid into said evaporation cavity;evaporating said dispersed liquid to generate a gas flow;conducting the gas flow out of the evaporation cavity;admixing one or several carrier gases and/or process gases to the gas flow when said gas flow has left the evaporation cavity;conducting the resultant gas flow out of the apparatus via an outlet; andholding back non-evaporated liquid so that no non-evaporated liquid will be discharged.
