Reformed coal production equipment

Abstract

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; and 
 mixed 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. 
   
     
     
         2 . The upgraded coal production equipment according to  claim 1 , characterized in that p 1  the equipment further comprises gas temperature measurement means, provided at the pyrolysis gas supply means, for measuring a gas temperature, and
 the mixed gas supply means includes
 gas flow rate adjustment means for adjusting a flow rate of the waste-heat gas and the low-temperature heating gas supplied to the pyrolysis gas supply means, and 
 control means for controlling the gas flow rate adjustment means based on the gas temperature measured by the gas temperature measurement means.
