COAL SILO FOR THERMAL POWER GENERATION PLANT AND STORED COAL RECIRCULATING CONTROL SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a coal silo for preventing the temperature rise of coal stored in a thermal power generation plant to prevent spontaneous firing thereof.;SOLUTION: The coal silo comprises tanks formed by partitioning a coal storage area into a plurality of sections with partition walls, a receiving conveyor 20 arranged above the storage area for carrying coal therein, a stacker 23 arranged above each tank for carrying the coal via the receiving conveyor into the tank, a deliverer 24 arranged under each tank for carrying the coal out, and a delivery conveyor 22 for carrying the coal out of the deliverer 24. The deliverer 24 delivers the coal from the tank storing relatively older coal in sequence. The stacker 23 arranged above the tank carries the coal therein and the deliverer 24 arranged thereunder carries the coal out. Thus, the first-in first-out operation of the stored coal is carried out.;COPYRIGHT: (C)2007,JPO&INPIT
