PULVERISED COAL INJECTION INTO BLAST FURNACE - A

The coal combustion in the regions of blowpipe and tuyere was modelled under the conditions of CSC’s No3 blast furnace in the second phase. The influence of operation conditions to coal burnout was comprehensively studied. It is found early ignition can be achieved with higher coal burnout when the double lance is employed instead of the
