对流过热器和再热器同一片管屏中各并联管子之间的热偏差是近年来在我国大容量电站锅炉中发现的一个新问题。有的管束热偏差系数高达1.3,影响到锅炉的安全运行,在苏联热力计算标准中没有这种热偏差的计算方法,在欧美的资料中也未见到这方面的
The thermal deviation between the parallel pipes in the same tube panel of the convection superheater and the reheater is a new problem found in the large-capacity power station boilers in our country in recent years. Some tube bundle thermal deviation coefficient of up to 1.3, affecting the safe operation of the boiler in the Soviet thermal calculation standard does not calculate this thermal deviation in Europe and the United States also did not see this information
