REFORMED COAL PRODUCTION EQUIPMENT

摘要

Reformed coal production equipment includes: a combustion furnace (124) for generating heated gas (11); a dry distillation gas supply pipe (101) for supplying dry distillation gas (14) generated at a dry distillation device to the combustion furnace; a vapor generator (125) to which a portion of the heated gas generated at the combustion furnace is supplied and which generates waste heat gas (13) by subjecting the heated gas to heat exchange; and a discharge pipe (52), a waste heat gas delivery pipe (54), a mixed gas delivery pipe (55), a blower (126), a mixed gas supply pipe (56), a mixed gas branching pipe (102), a flow rate adjustment valve (103), and a mixed gas communication pipe (104) supplying, to the dry distillation gas supply pipe, the waste heat gas and low-temperature heated gas (12) formed by indirectly heating dried coal by the heated gas at the dry distillation device (121).

1. Upgraded coal production equipment including
drying means for drying coal, indirect-heating pyrolysis means for performing pyrolysis on the dried coal by indirectly heating the dried coal by use of a heating gas, and cooling means for cooling the coal subjected to the pyrolysis, characterized in that the equipment comprises:
heating gas generation means for generating the heating gas;pyrolysis gas supply means for supplying the heating gas generation means with a pyrolysis gas generated in the indirect-heating pyrolysis means;waste-heat gas generation means for receiving supply of part of the heating gas generated in the heating gas generation means and generating a waste-heat gas by subjecting the heating gas to heat exchange; andmixed gas supply means for supplying the pyrolysis gas supply means with the waste-heat gas and a low-temperature heating gas generated when the heating gas heats the coal indirectly in the indirect-heating pyrolysis means.
