Abstract
A process for feeding a second stream of pulverulent materials into a pneumatic conveying line carrying a first controllable flow of pulverulent materials is presented. The second stream of pulverulent materials is fed at a controlled rate and the control of the first flow is rendered insensitive to disturbances caused by the feeding of the second stream by directly or indirectly controlling the first flow upstream of the injection point of the second stream.
Claims12
A process for supplying pulverulent materials in a pneumatic conveying system, including the steps of:
- generating a first stream pulverulent material in a conveying line;
- injecting a second stream of pulverulent material into said conveying line and into said first stream of pulverulent material;
- and
- controlling the rate of flow of said first stream of pulverulent material in said conveying line at a point in said conveying line upstream of the point of injection of said second stream of pulverulent material to render said first stream of pulverulent material insensitive to any disturbances caused by the injection of said second stream of pulverulent material into said first stream of pulverulent material.
Apparatus for supplying pulverulent materials in a pneumatic conveying system, including:
- means for generating a first stream of pulverulent material in a conveying line;
- means for injecting a second stream of pulverulent material into said conveying line and into said first stream of pulverulent material;
- and
- means for controlling the rate of flow of said first stream of pulverulent material in said conveying line at a point in said conveying line upstream of the point of injection of said second stream of pulverulent material to render said first stream of pulverulent material insensitive to any disturbances caused by the injection of said second stream of pulverulent material into said first stream of pulverulent material.
