1、 等离子点火系统中： 等离子喷枪采用目前国际先进的管状等离子发生器，它属于旋气稳定压缩的等离子发生器。从热效率角度看，管弧等离子发生器比同轴磁稳式等离子发生器的热效率高10%左右，管状电弧加热器的电极烧损率低、电极寿命长、气流污染小。供电装置采用IGBT晶体管整流电源，功率因数可以达到0.95以上，最大限度减少电网中的无功功率，同时最大程度的减少对电网的谐波干扰。煤粉燃烧器采用多级浓缩方式。各级浓缩器之间的距离可以进行调整，从而保证了煤粉的浓缩效果，达到等离子点火最合适的煤粉浓度。等离子喷枪与煤粉燃烧器同轴，保证等离子喷枪电弧火焰与煤粉运动具有相同的轴向方向，同时还能够卷吸煤粉，使等离子喷.....
