PNEUMATIC TRANSPORTING PULVERIZED COAL DISTRIBUTOR USING SWIRL ZET STREAM

摘要

PURPOSE: A pulverized-coal distributor using swirling jet stream is provided to ensure stable operation of a system since fuel is uniformly supplied to each burner and thus flame becomes uniform spatially or temporally. CONSTITUTION: A pulverized-coal distributor using swirling jet stream comprises a pulverized coal distribution container(10), a supply line(20), a plurality of branch lines(30), and a jet-steam spraying unit(40). The pulverized-coal distribution container supplies pulverized coal using carrier gas. The supply line supplies the pulverized coal and the carrier gas to the pulverized-coal distribution container. The branch lines distribute and discharge the pulverized coal and the carrier gas from the pulverized-coal distribution container. The jet-stream spraying unit sprays jet stream to the pulverized coal in the pulverized-coal distribution container. In order that the pulverized coal is uniformly distributed to the branch lines by swirling stream, the jet-stream spraying unit applies swirling force to the pulverized coal in the pulverized-coal distribution container.
