METHOD AND DEVICE FOR INCREASING THE EFFECTIVENESS IN THE HEATING OF FINE-PARTICLE SOLIDS IN FLOW TUBES

摘要

In a pneumatic conveying heater or drier for dispersed solid particles, a pulsating device in the form for example of a rotary throttling disk is arranged in the circulation conduit for the conveying stream of hot gas so as to periodically accelerate and decelerate the conveyed solid particles, thus increasing the efficiency of the heat transfer.
