Abstract
A pyrolyzed coal quencher includes: a first water spray tube 79 that sprays water on pyrolyzed coal having a temperature of 300° C. or more obtained after pyrolyzing coal; a first cooling tube 80 that performs indirect cooling on the pyrolyzed coal obtained after spraying water by the first water spray tube 79 to a temperature of 100° C. or more; a second water spray tube 82 that sprays water on the pyrolyzed coal cooled by the first cooling tube 80 such that the pyrolyzed coal has a desired water content; and a second cooling tube 83 that performs indirect cooling on the pyrolyzed coal cooled by the first cooling tube 80 to a desired temperature of less than 100° C. Thus, the pyrolyzed coal can be promptly cooled and adjusted to a desired water content.
