Abstract
The formation of nitrogen oxide in pulverized coal combustion is analysed by experiments in a 500 kW test rig and by numerical predictions. This study extracts some of the dozens of parameters that were investigated during the trials. It turned out that the huge number of process variables that have an impact on NOx formation can be reduced to a smaller figure by an appropriate data analysis. Major parameters presented in this contribution are the fineness of the coal dust and the amount of swirl. Special emphasis is put on the fact that the level of NOx concentration must necessarily be monitored together with the degree of bumout of the coal dustKeywords
