Analytical Models for Industrial Gas Burner Design. Part 1. Modeling Methods

摘要

The development and use of quantitative techniques in industrial gas burner design is described. These techniques make use of an array of fluid-dynamic and chemical-kinetic approaches, combined in such a way as to provide optimum analytical tools for different aspects of industrial burner design. An example is provided in which aerodynamic analyses are used to define a combustor model. This combustor model, incorporating detailed methane chemical kinetics, provides design data on the performance of an industrial gas burner. Emphasis is on the prediction of the emissions characteristics of the burner and on methods for controlling NOx emissions through combustion process modifications. Appendices provide descriptions of both the aerodynamic analysis to investigate the effects of design variation on the flowfield, and the combustor model used to obtain burner performance results.
