一、锅炉清灰剂锅炉清灰剂在国外已应用多年,上海、辽宁等省市已在进行强制性推广,取得了显著效果。清灰剂的作用有两个:一是把原来沉积的灰垢除去,二是预防新的灰垢的产生。使锅炉受热面传热良好。我们知道,钢的导热系数是39千卡/米·时·℃(20℃),而灰的导热系数仅为0.1千卡/米·时·℃左右。据测算,锅炉受 First, the boiler cleaning agent Boiler cleaning agent has been applied abroad for many years, Shanghai, Liaoning and other provinces and cities have been in the mandatory promotion, and achieved remarkable results. The role of cleaning agent has two: First, remove the original deposition of gray scale, the second is to prevent the emergence of new gray scale. The heating surface of the boiler heat well. We know that the thermal conductivity of steel is 39 kcal / m · ℃ · (20 ℃), while the thermal conductivity of ash is only 0.1 kcal / m · ℃ · ° C or so. It is estimated that the boiler by
