Abstract
A bin system and a char recovery unit are provided with: a bin for storing char; three char discharge lines placed at the predetermined slope angle for causing the char to fall with the force of gravity so as to discharge the char into the bin; four switching lines placed at the predetermined slope angle for causing the char to fall with the force of gravity so as to feed the char stored in the bin; and assist gas feed units as assist devices for assisting the flow of the char that falls with the force of gravity through the char discharge lines. This allows for equipment downsizing.
Claims15
A bin system comprising:
- a container for gathering or storing powder;
- a plurality of powder discharge lines placed at a predetermined slope angle, for causing the powder to fall with the force of gravity so as to discharge the powder into the container;
- a plurality of powder feed lines placed sloping at a predetermined slope angle, for causing the powder to fall with the force of gravity so as to feed the powder gathered or stored in the container;
- and
- an assist device for assisting flow of the powder that falls with the force of gravity through the plurality of powder discharge lines.

A char recovery unit for recovering an unburned portion of coal from product gas produced by gasifying the coal, comprising:
- a first separation device coupled to a production line of the product gas;
- a second separation device coupled to a first gas discharge line of the first separation device;
- a bin coupled to a first unburned portion discharge line of the first separation device and to a second unreacted portion discharge line of the second separation device;
- a plurality of unreacted portion feed lines for feeding an unreacted portion from the bin to an unreacted portion return line;
- and
- an assist device for assisting flow of the unreacted portion that falls with the force of gravity through each of the unreacted portion discharge line or each of the unreacted portion feed lines.
