ABSTRACT:
The process for combustion of coal dust with combustion air in burners and for reducing the production of NO.sub.x during the combustion. Combustion air is fed to the burners in form of primary air and secondary air. The burners are supplied coal dust through the primary air in a mixture of coal dust and primary air. A primary gas is generated with combustible gaseous components from the mixture of coal dust and primary air, through pyrolysis of the coal dust in the ignition region of the burners. In the ignition region, there is lowered the mean ratio of oxygen components in the primary gas to the oxygen amount required to burn freely released combustible gaseous components of the primary gas by reducing the oxygen component in the primary gas and/or injecting the primary gas with a combustible external gas.
