Abstract:
Large rectangular gas ducts installed in power plants usually need inner supports to ensure their stability. Generally two schemes are used for setting inner supports. One is National Standard Specification (NSS) and the other is an American Combustion Engineering company design criterion (CE). The design level of inner supports in flue pipe has a great effect on flow distribution. In this paper, three kinds of inner supports which are common in power plants are simulated by using computational fluid dynamics (CFD). Through a comprehensive analysis of their flow fields and pressure, it can be concluded that NSS inner supports which are thinner, vertical to each other and have more rows is the best design scheme among these three kinds of inner supports.
