摘要:
The invention proposes an arrangement for burning blast furnace off-gas from a bleeder valve. It comprises a bleeder valve (20) having a fixed hollow valve body (22) defining an outlet (26) and a valve seat and a movable obturator (24) that cooperates with the valve seat for closing the bleeder valve and releasing blast furnace off-gas through the outlet. The arrangement includes an apparatus for combustion of blast furnace off-gas released by the bleeder valve (20). This apparatus is characterized by an ignition device (32, 38, 40, 42, 44) that is arranged on or adjacent the valve body or the moveable obturator of the bleeder valve (20) itself. The ignition device (32, 38, 40, 42, 44) has its spatial ignition range located downstream the outlet in a region where blast furnace off-gas released through the outlet mixes with ambient air when the obturator is in an open position so as to allow open-air combustion of blast furnace off-gas released into ambient air at the location of the bleeder valve.
