摘要：

This report describes the nitrogen distribution in coal pyrolysis at different temperatures and oxygen partial pressures to allow discussion of the influence of different gas components on the DeNOx capability of the pyrolysis gases and tar species. Test runs with nitrogen-free reburn fuels and with coal pyrolysis gas showed that the nitrogen concentration, especially in the tar components of the pyrolysis gas, appears to have a positive effect on NOx reduction in the reburn zone of the combustion reactor.
