PNEUMATIC TRANSPORT-TYPE PULVERIZED COAL DISTRIBUTOR EMPLOYING SWIRLING JET STREAM

摘要

The present invention provides a pneumatic transport-type pulverized coal distributor employing a swirling jet stream, the distributor comprising: a cylindrical pulverized coal-distributing chamber into which pulverized coal that is a raw material is fed by a carrier; a feed line attached to the pulverized coal-distributing chamber such that the pulverized coal and the carrier gas are vertically fed into the pulverized coal-distributing chamber; a plurality of branch lines attached to the pulverized coal-distributing chamber such that the fed pulverized coal and carrier gas are vertically discharged from the pulverized coal-distributing chamber through the branch lines; and a jet stream injection means which injects a gas of air or nitrogen to the pulverized coal, fed into the pulverized coal-distributing chamber, to impart a swirling force into the pulverized coal-distributing chamber such that the fed pulverized coal is distributed uniformly into the plurality of branch lines by a swirling stream.
