Claim:
1. A water evaporation system, comprising: a heater for heating a pressurized solution having a water content therein, said heater including a coil through which the pressurized solution passes when being heated by said heater; an evaporation unit having a nozzle, the heated and pressurized solution passing through said nozzle to flash the water content in said heated solution to steam; said nozzle for spraying the pressurized solution into a mist, said nozzle having two members, with at least one said member being movable, a space between said two members defining an orifice, said movable member subjected to a force of the upstream pressurized solution to increase a size of said orifice, and said movable member subjected to an oppositely-directed force to decrease the size of said orifice, whereby the upstream pressure of the pressurized solution is controlled by the extent of the oppositely-directed force on said movable member; a supply of an abrasive; and an inlet to said water evaporation system for receiving an abrasive from said supply of abrasives, said abrasive passing through components of said water evaporation system, including said nozzle, to remove residue from internal surfaces thereof.
