Abstract
An ultrasonic fog generator can be used to advantage in injecting a fog into the input air of a combustion chamber, in order to improve efficiency and reduce the noxious emissions in the exhaust. In accordance with one form of the disclosure, a heat exchange is utilized to advantage in a turbine system in reheating compressed air that has been cooled as the air was fogged, the reheated air being input to the combustion chamber. In another form of the disclosure an adjustable heat exchange is used to controllably heat input air before the fogging thereof, the level of heat exchange depending on properties of the input air and the level of fogging to be implemented.
Claims7
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 said combustion chamber, and means communicating with said combustion chamber for obtaining power from said combustion;
- the improvement comprising:
- an ultrasonic fogging device communicating with said input air, said fogging device being adapted to receive a fogger air supply and a fogger water supply, and to generate a fog in said source of input air;
- an adjustable heat exchanger for exchanging heat from the combustion chamber exhaust to the input air to be fogged;
- and
- means for adjusting the level of heat exchange of said heat exchanger in accordance with properties of the input air and the level of fog being generated.
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 said combustion chamber, and means communicating with said combustion chamber for obtaining power from said combustion;
- a method comprising the steps of:
- generating a fog in said source of input air;
- exchanging heat from the combustion chamber exhaust to the input air to be fogged;
- and
- adjusting the level of heat exchange in accordance with properties of the input air and the level of fog being generated.
