Abstract
A method and apparatus for burning fuels with air, with reduced production of NOx, involves the premixing of water vapor with the fuel prior to the burning operation. Because of the low retention of water vapor at low temperatures, means are provided for preheating the fuel and spraying water into the fuel so that water vapor will be taken up by the heated fuel in sufficient quantity to provide the desired results. Various embodiments of apparatus are illustrated.
