在进行锅炉对流传热计算时首先应确定总传热系数K(千卡/米~2时℃)。过去总传热系数K是用下式计算的式中-对流受热面的有效利用系数,它是考虑到烟气冲刷受热面时的完全程度,由于锅护组成线图以及对流管束中且有挡烟板等影响,在对流管束中造成局部烟气冲刷不到的所谓“死空间”。 During the convection heat transfer calculation of the boiler, the total heat transfer coefficient K (kcal / m ~ 2 o’clock) should be determined first. The past total heat transfer coefficient K is calculated using the following formula - effective convection heating surface utilization factor, which is taking into account the flue gas wash the heating surface of the complete degree, as a result of pot protection composition diagram and the convection tube bundle Soot and other effects, resulting in the convection tube bundle local flue gas scouring less than the so-called “dead space ”.
