Mexico and coal

The U.S. Geological Survey (USGS) reports that Mexico produced 11.9 Mt of coal in 2007, which was an increase of 9% compared with production in 2006. In 2008, Mexico produced 9589 kt of sub-bituminous coal. The same year Mexico imported 2696 kt of sub-bituminous coal. Coal Consumption. Mexico consumed nearly 21 million short tons of coal in 2019.

Pulverizer Fineness and Capacity Enhancements at …

capability can be used to increase the pulverizer and boiler capacity with the present coal or to maintain the present boiler load with a coal that is more difficult to pulverize. At Danskammer, the existing pulverizer capacity was increased by more than 15 percent while the coal particles larger than 50 mesh were essentially eliminated.

Coal Pulverizers

Raw coal is fed to pulverizer from the coal feeder via a center feed pipe. The coal is grounded between the three grinding rollers and the rotating table in the pulverizer. Pulverized coal is simultaneously dried by the drying gas fed from bottom part of pulverizer and carried into the separator fixed at the top of pulverizer.

Coal Pulverizer Explosions

Pulverizer Generic Type: The explosion frequency for vertical spindle pulverizers is about twice that of the ball pulverizers and about five times that of the attrition pulverizers. With bituminous coals the vertical spindle pulverizers show a higher explosion frequency while the ball and attrition pulverizers have equivalent lower frequencies.
