Title:
L-SHAPED HEADER OF STEAM GENERATOR INCLUDING SPIRAL TUBE AND A COUPLING STRUCTURE OF L-SHAPED HEADER AND TUBE
Document Type and Number:
WIPO Patent Application WO/2019/035671
Kind Code:
A1
Abstract:
The present disclosure relates to an L-shaped header of a steam generator including a spiral heat transfer tube, and a coupling structure between the L-shaped header and the heat transfer tube, wherein an upper end and a lower end of a heat transfer tube assembly configured with a plurality of heat transfer tubes are vertically formed, and the upper and lower ends of the heat transfer tube assembly are vertically coupled to a bottom side or a top side of the header. Therefore, the heat transfer tubes constituting the same concentric circle may use the heat transfer tubes formed with the same shape, thereby improving the manufacturability of parts and reducing the manufacturing cost.
