Title:
SOLID FUEL CRUSHING DEVICE AND POWER PLANT AND OPERATION METHOD OF SOLID FUEL CRUSHING DEVICE
Document Type and Number:
Japanese Patent JP2022130855
Kind Code:
A
Abstract:
To inhibit deterioration of controllability of a cold gas damper and control a carrier gas preferably.SOLUTION: A solid fuel crushing device 100 includes: a crushing machine 60 which crushes a solid fuel; a blower part 30 which has a cold gas passage 30b in which a cold gas circulates and a hot gas passage 30a in which a hot gas circulates and which supplies the hot gas or a mixed gas formed by mixing the hot gas with the cold gas to the crushing machine 60 as a carrier gas for carrying the crushed solid fuel; and a first seal gas supply part 80 which supplies a seal gas to the crushing machine 60. The cold gas passage 30b is provided with a cold gas damper 30d which adjusts an opening to adjust a flow rate of the cold gas circulating therein. The first seal gas supply part 80 has a first seal gas pipeline 81, which is connected to the downstream side of the cold gas damper 30d in the cold gas passage 30b at its upstream end and, supplies the cold gas circulating in the cold gas passage 30b through the first seal gas pipeline 81 to the crushing machine 60 as the seal gas.SELECTED DRAWING: Figure 2
