Abstract:The present paper presents the contribution on the performance enhancement study of a regenerative Ljongstrom type air preheater. The experimental analyses are carried out to study the performance enhancement of the system by regular artificial roughening of the heat transfer elements using pin-shaped turbulators (promoters). An experimental test rig is designed and fabricated to simulate the transient operation of the rotary air-preheat system. To study the hydraulic and thermal processes and their combined i… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
