PULVERIZED COAL SUPPLY SYSTEM CAPABLE OF PREVENTING INFLOW OF THE PULVERIZED COAL OF AN IRREGULAR PARTICLE SIZE

摘要

PURPOSE: A pulverized coal supply system is provided to prevent a pipe from clogging with the pulverized coal and to prevent damage to a device.;CONSTITUTION: A pulverized coal supply system comprises a first lock hopper(101), a second lock hopper(102), a vertical pipe(111), a tilt pipe(112), a standard size pulverized coal supply pipe(113), an excessive size pulverized coal supply pipe(114), a pulverized coal supply pipe(115), a first transfer gas supply unit(121), a second transfer gas supply unit(122), a transfer gas blower unit(131), a perforate plate(132), and an angle film(151). The first lock hopper stores pulverized coal passing through a novelty process, and the second lock hopper stores excessive size pulverized coal. The vertical pipe is vertically connected to the lower part of the first lock hopper, and the tilt pipe is connected to the vertical pipe at a predetermined angle. The standard size pulverized coal supply pipe is extended from the tilt pipe and is connected to a screw feeder(142). The excessive size pulverized coal supply pipe is extended from the tilt pipe and is connected to the second lock hopper. The first transfer gas supply unit supplies the transfer gas to the pulverized coal supply pipe and the second transfer gas supply unit supplies the transfer gas to the transfer gas blower unit. The transfer gas blower unit is connected to the lower part of the tilt pipe, and the perforate plate includes a plurality of pores(133). The angle film classifies the standard size pulverized coal and the excessive size pulverized coal.;COPYRIGHT KIPO 2013
