Pulverised Coal Combustion - an overview | ScienceDirect ...

Pulverised coal combustion in large utility boilers can result in the production of significant amounts of oxides of nitrogen (NOx - principally NO in this type of plant). Although some of this NOx is formed from nitrogen in the combustion air, the principal source of NOx is generally the nitrogen contained in the coal itself since the latter is available in more reactive form.
