The experiment results prove that the boiler coking is largely reduced and the temperature difference of two sides of horizontal gas-pass is very small, when the 330MW boiler operate, the pressure of primary hot air parison is controlled beyond 12.0～12.5KPa, the O2 content of air pheheater is controlled about 3.0%, the door of OFA is opened to 30%, the buffle of the inner secondary air sleeve is adjusted to the minimum, the outer secondary air swirling strength and the baffle of the outer secondary air sleeve is regulated to the maximum and the outlet temperature of pulvervised mill is kept in 70℃.

试验结果表明，330MW运行时，一次热风母管压力控制在12.0～12.5kPa以上、空气预热器实际氧量控制在3.0％左右、燃尽风门开至30％、内二次风量套筒挡板调整在最小、外二次旋流强度和外二次风套筒挡板调整到最大、磨煤机出口温度维持在70℃，此时锅炉结焦大幅度减轻，水平烟道两侧烟温差非常小。优化试验完成后，进行了单烧灵武烟煤对比，结果是：掺烧高灰熔点的银北煤后，炉膛结焦大幅度减轻，锅炉过热器减温水量较小，主蒸汽压力易提高，带负荷能力正常；再热器烟气挡板开度较大、减温水量较小；风机电耗较小。
