Numerical Model for the Combustion of a Thermal Lance

Abstract

A mathematical model for the operation of a thermal lance is developed and validated, with the focus on its heat transfer and kinetics behavior. It has been found that there is a “window” of combustion rates in which the thermal lance can operate, which is mainly dictated by the oxygen partial pressure. The particular value of the combustion rate can be set by adjusting the flow rate of the oxygen supply, which is practically done by manipulating the oxygen supply pressure. An open issue is the lack of experimental kinetics data for thermal lance combustion.
