Munk, M

For use in conjunction with a combustion-based system including a combustion chamber having an exhaust, a source of input air and a source of fuel for providing input air and fuel to the combustion chamber, and means communicating with the combustion chamber for obtaining power from the combustion; the improvement is described comprising: an ultrasonic fogging device communicating with the input air, the fogging device being adapted to receive a fogger air supply and fogger water supply, and to generate a fog in the source of input air which has a droplet size of the order of ten microns or less, and evaporates to dryness in the input air; means for sensing noxious emissions in exhaust gases from the combustion chamber; and means for controlling the fogging device in accordance with the sensed noxious emissions.
