ABSTRACT:
The invention relates to a method and an apparatus or system for evaporating liquid and comprises spray drying, spray concentration and conditioning (i.e. cooling and/or moistening) of combustion gas or flue gas. Liquid is atomized or sprayed into an evaporating chamber from a liquid spraying or atomizing device arranged centrally in the upper part of the evaporating chamber, and an unobstructed coherent flow of warm gas, such as combustion gas or flue gas is simultaneously directed substantially axially into the evaporating chamber and upwards towards the atomizing device. Gas phase is currently being discharged from the evaporating chamber at a level substantially below that of the atomizing device, whereby the axially directed gas flow will tend to turn back in a fountain-like manner and spread the atomized liquid so as to continuously form a "protecting umbrella" over the fountain-shaped gas flow, whereby the combustion gas will be properly cooled before contacting the inner walls of the evaporating chamber.
