Abstract:-

Low Calorific Value (CV) coal is used in large quantity as compared to High Calorific Value coal in Cogeneration Power Plant (CPP) at Gayatrishakti Paper & Board Limited Unit-1, Vapi. But the moisture content in Low CV coal is very high about 35% - 45% (wet basis) which is not acceptable due to sticky property of coal, hence leads to increase in operation and maintenance costs attributed to handling of wet coal. So drying of coal is necessary to use Low CV. The drying performance of Low CV coal particle in laboratory scale with and without vibration assisted fluidized bed dryer was investigated under various operating condition: Inlet air temperature (60 - 80℃), superficial air velocity (0.14 – 0.43 m/s), bed height ( 20-60 mm), particle size (1-2,2-3,3-5 mm), frequency (110 - 340 Hz). The drying results shows that the moisture content with respect to time decreases with an increase in temperature, air velocity, and vibration frequency, and also increases with an increase in bed height and particle size.
