Abstract
A method and an apparatus of operating a boiler fired with liquid or gaseous hydrocarbons are described. Fuel and atomizing air are supplied to the burner of the boiler wherein the atomizing air is subjected to a moistening process prior to mixing with the fuel. Heated water is vaporized and is contacted with the atomizing air. The generated water vapor together with the atomizing air is supplied to the burner. In this manner, the portion of the NO,emissions in the flue gas of the boiler can be reduced.
