Mathematical Modelling of Swirling Pulverized Coal Flames

摘要

The development and application of a mathematical model to account for all theimportant processes occurring in the combustion zone is presented. This model is to be used for research into the reduction of the generation of pollutants in the combustion zone. It will be a powerful tool for both determination of the missing information at experimental scale and for scaling up experiments. The model is based on a three dimensional simulation for turbulent flow computations and should be accompanied by models of combustion and heat transfer. Various aspects of the modeling are investigated. The results of these investigations are used in a study of the characteristics of flames fired with a pulverised coal burner.
