STUDY ON MATHEMATICAL MODELLING OF\=FLUIDIZED\|BED WITHOUT PERFORATED\|PLATE\=AND ITS INDUSTRIAL APPLICATION

The mathematical modelling of fluidized\|bed without the perforated\|plate has been studied.The fluidization expression given by the has been used in tests and as a criteria of fluidization quality. A 0\^75m\|ID clear plexiglass fluidized\|bed without the perforated\|plate was used for a amplificative simulator. The computer and differential pressure transducer etc. were connected to the fluidized\|bed without the perforated\|plate for processing data in a real\|time on\|line operation. Based on the mathematical modelling, a 1\^2m\|ID commercial fluidized\|bed without the perforated\|plate chlorinator has been designed for chlorinating titanium\|rich slag containing approximately 85% TiO\-2, 6\^7% MgO and CaO impurites to produce TiCl\-4. The chlorinator has run continuously for 55 days with a good fluidization.
