OTF-1200X-S-FB is a Fluidized Bed Verticel Furnace with 1'' O.D Quartz Tube (2'' O.D enlarged central area) for powder CVD applications.
It consists a vertical-positioned cylindrical heating chamber which surrounds the quartz tube with a built-in filter right in the lower middle section of the central heating zone.
Its filter is a porous (15 ~ 40 microns) quartz frit that allows the controlled gas flow pass through and float the particles on a cushion of the gas stream where the interaction between the solid and gaseous materials take place.
SPECIFICATIONS
Fluidized Zone
•Provides uniform distribution of the gas blast over the entire cross section of the tube chamber •Solid particles are suspended by an upward gas flowing •Excellent heat transfer and coating to every single suspended particles •Processed materials can be discharged from the top side of the tube after the cap is been taken off
•Note :
The gas is passed upward through the fluidized bed at a high enough velocity to lift the particles.
However, particles may be swept away from the tube chamber entirely if the velocity was set too high.
Depends on the particle size, you may want to adjust the gas-in pressure and flow rate until particles are lifted and move turbulently inside of the tube.
