永安电厂燃用福建低挥发分无烟煤。1号炉(WGZ—130/39—9)制粉系统的粗粉分离器为仿苏型,φ2850,细粉分离器为仿苏A3型;φ1850,磨煤机为DTM250/390型球磨机。试验及运行表明:要使煤粉合乎燃烧要求的细度R_((?)0)≤6～8%,制粉系统的通风量只能控制在15000～16000M~3/H范围左右(粗粉分离器的辐向导叶调节器开度已在最低位置～30°)。这样,不仅煤粉产量受通风量不足限制,而且分离效果不良。粗粉
Yong’an Power Plant burning Fujian low volatile anthracite. The No. 1 oven (WGZ-130 / 39-9) pulverizing system for the powder separator for the imitation Su-type, φ2850, fine powder separator for the imitation Su-A3; φ1850, coal mill for the DTM250 / 390 ball mill. The experiment and operation showed that the ventilation rate of pulverizing system can only be controlled in the range of 15000 ~ 16000M ~ 3 / H (coarse powder Splitter guide vane regulator opening in the lowest position ~ 30 °). In this way, not only the yield of pulverized coal is limited by insufficient ventilation, but also the separation effect is poor. meal
