This machine is driven by the 22 kW asynchronous motor by means of the reduction planetary gear of the resultant ratio 15.33.The static characteristic of this motor as well as the drive system first torsional eigenform of frequency 4.2 Hz are shown in Figs. 2a and 2b respectively.

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 its ignition temperature.

Pulverised Coal An Overview Sciencedirect Topics

Pulverized coal is used in many utility boilers. Due to the small particle size pulverized coal can be transported pneumatically. Coal particles contain four major components moisture volatiles char and ash. When heated the moisture is dried and the volatiles are devolatized. The volatile vapor mixes with oxygen and the mixture burns.
