摘要
根据几台锅炉的实测数据推算不同煤质对不同受热面的实际灰污系数和各种受热面的实际传热系数。推算结果表明,不同煤质对受热面灰污特性的影响程度相差较大,其对锅炉运行特性的影响比较明显。所列举煤质对受热面灰污系数的影响与国外某些现行标准的推荐值有时相差较大,需要锅炉试验、设计、运行中积累数据对其进行修正。
Based on practically measured data from several boilers, the real fouling coefficient of different coal quality and of different heating surfaces, as well as real heat transfer coefficient of various heating surfaces have been calculated. Results of calculation show that the influence of different coal quality upon fouling coefficient of the heating surface has comparatively large difference, and affecting more obviously upon the operation performance of boilers. The listed influences of coal quality upon fouling coefficient of heating surfaces have comparatively large difference with recommended values in some standards currently in effect at abroad, needing to accumulate data from boiler test, design, and operation for correcting the said influences.
