Abstract
A method and apparatus for humidifying a gas flow includes means for atomizing a liquid into a gas feed line and means for heating the liquid. The atomizing means is provided in a spray chamber, with a heat-exchanger region for at least partially evaporating the liquid being arranged adjacent to the spray chamber. The heat-exchanger region has a multiplicity of flow passages for gas flows which are to be humidified, which flow passages are at least partially delimited by heat-exchanger surfaces for condensing and evaporating the liquid.
