The Influence of Jet Flows on Nox Generation during a High-temperature Air Combustion Process

Presented are the NOx generation mechanism during a fuel combustion process and various influencing factors. In addition, in connection with the specific features of high temperature air combustion (HiTAC) and the basic theory of jet flows the authors have investigated the influence of an entrainment of fuel and air jet flows on NOx generation rate occurring at the HiTAC mode. The results of the investigation may provide a theoretical basis for the selection of a rational design and operating parameters as well as for the attainment of super low NOx emissions and sizable energy savings when operating at the HiTAC mode. Furthermore, they can also promote the industrial application and popularization of this advanced HiTAC technology in China.
