| Abstract: | There are different structural characteristics between glass tube and steel tube air preheater. In this paper, the entrance and exit local resistance performances are studied when air flows through the tubes of a glass tube air preheater. From experiment, relations among the local resistance, throughfare area rate, and the tube lenghth sticked cut of tube plane plate are developed. A chart and an experiential formula are also recommended. |

| Keywords: | glass tube preheater area rate local resistance |
