METHOD OF PNEUMATIC TRANSPORTATION OF POWDER- LIKE MATERIALS FROM ASH COLLECTOR HOPPERS Russian patent published in 2001 - IPC

FIELD: pneumatic transportation of materials. SUBSTANCE: method comes to directing powder-like material from hoppers to transportation pipeline, fluidizing the material and moving it along transportation pipeline consisting of section. After fluidizing the material, it is transported in each section in ascending current formed in ascending section of pipeline, part of fluidizing agent is withdrawn from upper space of ascending section and power-like material is moved at tilting to other section of transportation pipeline. Corresponding reservoir is used for delivering powder-like material into first section of transportation pipeline where free-laying layer of powder-like is formed. This material is fluidized at side of lower part of free-laying layer, part of fluidizing agent is drawn out of reservoir space over free-laying layer and material is moved in ascending current. EFFECT: reduced consumption of air for transportation of powder-like material, improved reliability of equipment. 1 dwg
