ABSTRACT:
The present moisturizer for air going into a combustion process has a venturi passageway through a liquid permeable, porous, open-ended, annular body surrounded by liquid such as water and a valve in the venturi passageway. The valve is spring-biased toward the air inlet end of the venturi passageway to provide a maximum flow restriction at low volume demand. The valve deflects air outward against the inside wall of the porous body which defines the venturi passageway for the purpose of enhancing the withdrawal of moisture from the porous body, particularly at low volume demands. At progressively higher volume demands, the valve is displaced by the air toward the air outlet end of the venturi passageway to enlarge the effective open area of the passageway around the valve. Preferably, the valve operates to keep the air velocity through the venturi passageway substantially constant at different air flow demands.
