Will the NTU heat transfer model suffice to determine the heating zone length of the screw conveyor or are there any other accurate methods of arriving at a solution? How does the commercial thermal screw conveyor manufacturers determine the effective zone length?
Process requirement: Heating biomass from 298K to 523K. Cp = 1.040 KJ/Kg K at a 0.01Kg/s mass flow rate of biomass
do u mean the GN U-Type screw conveyor is performance proven industrial bulk material handling equipment for over 10 years. GN U-Type screw conveyors move wet or dry materials either horizontally, on an incline or vertically. GN screw conveyors can be used to conveying material, feed material, distribute material, collect material or mixing material. Depends on different applications, with special cover and gasket, they can be made as dust free or weather proof.
Maan S.M. Al-Dabbagh Yes, GN U-Type screw conveyor is the one that I'm referring to. However, how do we go about calculating the heating zone for such a conveyor? Do we use the NTU approach to arrive at the solution?
From calculating the diameter and surface area with an estimate of the thermal conductivity
