摘　　要：为解决现有含锥套式混合室的高炉喷煤用烟气炉因混合室出口处温度往往超标而导致出口处钢架构易变形塌陷、内部耐材随之塌陷损坏的问题,提供一种改进型高炉喷煤烘干烟气炉,可有效避免混合室出口处因高温受损情况的发生,同时也能确保所得的烘煤气体达标。The improvement fume furnace solves of deformation and cave in the steel structure of the mixing chamber outlet, followed by interior refractory destruction which is under high temperature frequently occurred at outlet of drogue type mixing chamber of pulverized coal injection system of blast furnace, and ensure coal drying gas up to standard while effectively avoid damage to mixing chamber in excessive heat.
