Kurz Instruments | Coal Power Plant Application

For energy production, coal pulverizers or mills are used to grind coal into a fine black powder so that the furnace can more easily burn it. Primary air feeds the coal pulverizer and acts as a carrier and dryer for the coal moving to the burner. An exhaust fan pulls the coal dust from the pulverizer and blows it through pipes into.

Coal Pulverizer Maintenance Improves Boiler Combustion - POWER .

Dec 1, 2015 . We have found that targeting an A/F ratio around 1.8 lb of air per lb of fuel is best. For some pulverizer types, such as ball tube mills and high-speed attrition mills, often a 1.6 A/F ratio is optimum. Never have we observed good combustion conditions or good mill performance with A/F ratios of 2.5 or greater.
