Coal Drying Improves Performance and Reduces Emissions

power plant, less coal needs to be fired. This reduces the burden on the coal handling system, conveyers and crushers. Also, since dryer coal is easier to convey, this reduces maintenance costs and increases availability of the coal handling system. Crushed coal is fed into the bunkers from where it flows by gravity to the coal feeders.

Ah, the Sound of Pulverizers - IQS Newsroom

Ah, the Sound of Pulverizers. You can almost hear the grinding and crushing as you say the word pulverizer – the consonants and vowels combine to create hard sounds as you enunciate through the syllables. I enjoy deepening my voice to emphasize the harshness of the word. You try… it's like a "grr" from the back of your throat.
