Abstract
In this work, the process of combustion of hydrocarbon fuel in the original burner of the evaporative type with the supply of superheated water vapor to the reaction zone is investigated using numerical modeling. N-heptane was used as a model fuel. The turbulent flow of gases was modeled on the basis of the RANS (Reynolds-averaged Navier–Stokes) approach. The combustion was simulated with the EDC (Eddy Dissipation Concept) model using a reduced chemical reaction mechanism. Calculation studies of the effect of steam on the processes occurring in the combustion chamber were carried out. Comparative analysis of the calculation results with experimental data showed good agreement in terms of the main integral parameters. The positive effect of the influence of steam injection into the active combustion zone of hydrocarbon fuel on the reduction of harmful emissions is shown.
