Modelling of drying of wet coarse particles of sludge in a conical spouted bed dryer
Resumen: In order to optimize the drying process at low
temperature, the influence of geometric factors and operating
conditions on drying time of wet coarse particle of sludge in a
conical spouted bed dryer has been analyzed by means of a
factorial experimental design. The effect of the geometric
factors and operating conditions on drying time has been
determined by a statistical analysis. Operation regimes of beds
consisting of wet coarse particles in a conical spouted bed
dryer have been determined by pressure drop fluctuations at
inlet gas temperatures from room temperature up to 120 ºC.
Results of drying modelling for beds of coarse particle wastes
at different regimes have been verified through some
experimental drying time of sludge.
