사이폰없는 실린더드럼에서 다중유로에 의한 응축수배출에 관한 실험적 연구

다국어 초록 (Multilingual Abstract)

Cylinder drum dryer tor paper drying is the method which drys the wetted paper flowing on surface of drum by steam. The condensate, which the steam transfers the heat to the surface of drum for paper drying and is condensed, must be removed for continuous drying. In this paper, the condensate removal and heat transfer characteristics were experimented according to steam pressure, revolution of drum and height of flow channel by multi-f1ow channel in cylinder drum without syphon. And these heat transfer characteristics were compared with the case of conventional type with syphon for condensate removal. As the experimental results, the minimum steam pressure existed for the removal of condensate by steam pressure without siphon, and heat transfer quantity in cylinder drum with multi-flow channel was approximately increased to 28% compared to conventional drum. Accordingly, application effect on this technology was expected to be great, but a lot of steam was exhausted with condensate, so this problem must be improved for the commercialization of cylinder dryer with multi-t1ow channels.
