Mean residence time and hold-up of solids in rotary kilns ...
Mean residence time and hold-up of solids in rotary kilns ...

The influence of operational variables on the mean ,residence time, (MRT) and hold-up of the solids in ,rotary, kilns has been investigated by many researchers. However, their reports on the influence of the feed rate on MRT, for example, are not consistent with one another. In this study, experiments are conducted on a 400 mm ID pilot ,kiln, with a cylindrical discharge dam.

Rotary Dryer Design 101: Retention Time
Rotary Dryer Design 101: Retention Time

Retention ,time,, also called ,residence time,, is the amount of ,time, that the material must be processed in the ,rotary, dryer in order to achieve the desired results.. The retention ,time, required for a given application is determined through balancing the necessary process parameters – particle size distribution, air flow velocity, temperature, and more – with the desired outcome; it can then ...

Modeling of a Rotary Drum Pyrolyzer - DiVA portal

ow in a rotary ,kiln, without reaction. ,Residence,-,time, distribution (RTD) is the main aim to study in this part, which was simulated by axial dispersion model (ADM). The model requires only one tting parameter that is dispersion coe cient (D ax), which was studied in parallel by two cases: constant value of D ax, and D axas a function of ,kiln,’s length.

Experimental study of residence time particle movement ...

Experiments were performed in a pilot scale ,rotary kiln, with coal and coke particles to study their mean ,residence time,, ,residence time, distribution, bed depth profile and ,time, spent at the bed surface. The influence of filling ratio on ,residence time, was studied with a uniform bed depth in the ,kiln,.
