ABSTRACT:
In a pneumatic conveyor system comprising a plurality of parallel transport pipes and a blower for passing air through the pipes at a high velocity to transport particulate solids, each of the transport pipes is provided with a flow regulator. The flow regulator in a first embodiment is a manual flow regulator which is preset to a predetermined airflow and allows fine adjustment in response to a variation of particulate-air ratio to keep the airflow constant. The flow regulator in a second embodiment cooperates with a process control computer so as to provide the air stream through each pipe with an optimum air flow velocity. Air flows at a rate sufficient to transport particulate solids at varying particulate-air ratios, reducing the capacity of a blower as well as saving power comsumption.
