Pulverizer Performance and NOx Emissions

Impact of Pulverizer Performance on Nitrous Oxide Emissions The combustion of solid carbon or “char” must be completed in a very short time. If air and carbon are not well mixed, combustion requires even more time. From the time a coal particle enters the furnace, it spends approximately 1 to 1.5 seconds above it’s ignition temperature.
