System for the pulsed pneumatic transport of ash from ash-collector bins

Results of investigations of the dependence of the percentage of voids on the shear force of a layer of ash, on the basis of which the design principle of the subassembly for the feed of ash to a transport pipeline is developed, are examined for optimization of ash flows in a pulsed regime. The schematic of a system of pulsed pneumatic transport of ash from the bins of ash collectors, and results of measurements during experimental operation of the system, as well as relationships for the calculation of its dynamic parameters are presented. Conclusions concerning the high reliability of the removal and pneumatic transport of ash over a distance of more than 80 m with minimal air consumption are drawn on the basis of results of the experimental operation.
