Experimental Study of Influence of Initial Air Temperature on Characteristics of Combustion of Diesel Fuel Atomized by Jet of Superheated Steam

This paper presents the results of an experimental study of combustion of diesel fuel at atomization by a steam jet and fuel presence in the mixing and gas generation zone at different temperatures of the air supplied to the burner chamber. The research aim is to develop a method of burning liquid hydrocarbon fuel atomized by a jet of superheated steam as a promising approach to increasing the combustion efficiency and reducing the content of harmful substances in combustion products. When the temperature of the primary air was increased to 200°, the flame temperature was found to grow, which led to reduction of the concentration of CO in the combustion products and increase in the NO \(_{\rm x}\)  content. After this value, no changes in the content of harmful substances were observed, which is probably due to the complete evaporation of the fuel in the gas generation chamber due to the heat of the supplied air.
