Airflow pace ought to be controlled for economical fluidization to occur. For an efficient drying procedure, airflow pace needs to be optimized. In case the velocity is just too large, then the fuel won't be heated to our goal temperature. And whether it is much too sluggish then fluidization is not going to occur.
Requires greater gas managing due to substantial recirculation of exhaust fuel for prime thermal effectiveness Procedure.
While, The underside of your chamber consists of a mesh/ perforated sheet for passage of of incredibly hot air through the plenum chamber, the highest is directly connected to the bottom of your Fluidization Chamber (also referred to as Enlargement Chamber) with the more info assistance of a D sort hollow tube inflatable gasket.
