Pulverized coal supply system, operation method thereof, and coal gasification power generation equipment

摘要

PROBLEM TO BE SOLVED: To provide a pulverized coal supply system, an operation method thereof, and a coal gasification power generation facility that can reuse pressurized gas for transfer of pulverized coal.SOLUTION: A pulverized coal supply system comprises: a first pulverized coal hopper; a pressurized gas collection line connected to the first pulverized coal hopper; and a pressure filter provided in the pressurized gas collection line to remove pulverized coal in pressurized gas collected from the first pulverized coal hopper. The pressurized gas collection line is connected to at least one of a buffer tank located on the downstream side of the pressure filter to store the pressurized gas collected from the first pulverized coal hopper or a second pulverized coal hopper provided in parallel with the first pulverized coal hopper.SELECTED DRAWING: Figure 2
