摘要：
The inventive device comprises a pipeline (1) for supplying a pulverised coal fuel, a channel (2) for supplying secondary air, a central tube (3) which is mounted in the pipeline (1) elbow by means of a flange (4) in such a way that it is longitudinally movable. The central tube (3) is provided with a plasmatron (5) which is placed therein on the side of a furnace chamber and is axially movable inside said tube (3) by means of a rod (6). A confuser (8) is fixed to the end section of the tube (3) by means of brackets (7) at an angle ranging from 0 to 18 DEG with respect to the longitudinal axis of the tube (3). The cross sectional area of the minimum diameter of the confuser (8) coincides with the cross sectional area of the plasmatron nozzle (9) when it is maximally pulled out, the confuser conicity being equal to 1:5 1:3. The passage aria of an annular channel in the pipeline (1) cut off by the confuser (8) is of 0.4-0.5 the pipeline (1) passage area.
摘要（中）：
本发明的装置包括用于供应粉煤燃料的管道（1），用于供应二次空气的通道（2），通过法兰（4）安装在管道（1）中的弯管的中心管（3） 以这样的方式使其可纵向移动。 中心管（3）设置有等离子体（5），该等离子体（5）放置在炉室的侧面，并且可通过杆（6）在所述管（3）内轴向移动。 通过支架（7）相对于管（3）的纵向轴线以0至18°的角度将迷你（8）固定到管（3）的端部。 混合器（8）的最小直径的横截面面积在最大拉出时与等离子体喷嘴（9）的横截面面积重合，约数为1:5:1:3。 管道（1）中由管道（8）切断的环形通道的通道匝道的管道（1）通道面积为0.4-0.5。
