product moisture content is 29.5 for an inlet coal moisture of 38. At the maximum coal feed rate product moisture content is 30.6. Test Matrix Two series of controlled tests were performed at Coal Creek Unit 1 with wet and dried lignite to determine the effect of the DryFineTM process on unit performance emissions and operation.

Use Of Coal Drying To Reduce Water Consumed In Pulverized

Use Of Coal Drying To Reduce Water Consumed In Pulverized

Oct 01 2005 Coal drying experiments were performed with lignite and Powder River Basin coals to determine the effects of inlet air moisture level on the equilibrium relationship between coal moisture and exit air relative humidity and temperature. The results show that for lignite there is a slight dependence of equilibrium moisture on inlet humidity level.
