Effect of ring groove in a heat-insulating insert on efficiency of its work in blast channel of blast furnace tuyere

One of the main disadvantages when supplying natural gas to air tuyere a blast furnace is low intensity its combustion inside channel. Ring groove on surface channel improves mixing with and increases completeness in it, but reduces durability. ways simultaneously solve these problems install heat-insulating ceramic insert The significantly heat losses through surface, due contact hot walls instead cold copper absence. This temperature at outlet. In addition, affects durability by reducing flow acting tuyere. this work, we studied influence ring parts efficiency work. Ansys 21.1 software, processes occurring installed having quadrangular section form or part circumferential direction, were simulated. It was established that improvement achieved using it from side supply.
