Combustion of liquid hydrocarbons sprayed by air jet

Abstract

In the present work, the combustion of liquid hydrocarbons sprayed by air jet was studied using diesel fuel as an example. The dependences of nitrogen oxides and carbon monoxide concentrations in combustion products on the fuel and air flow rates were investigated using an atmospheric burner device. It is shown that while diesel fuel sprayed by air jet there is a wider range of operating parameters in comparison with steam spraying due to the flameout. Compared with atomization by air jet at room temperature, steam and heated air spraying have advantages, for these regimes the NOx concentrations are observed to be lower.
