Document Type and Number:
WIPO Patent Application WO/2007/114048
Kind Code:
A1
Abstract:
A support structure for a heat transfer tube, capable of preventing a reduction
in reliability and durability of the tube. A vapor generator (heat exchanger)
has a lower drum (container), the heat transfer tube installed in the lower drum,
and a pipe support plate installed in the lower drum and in which a heat transfer
tube insertion hole is opened in the thickness direction of the plate. In the
vapor generator, a support part for supporting the heat transfer tube is provided
on the inner surface of the insertion hole, at an axially intermediate part in
the thickness direction of the pipe support plate, and a region between the support
part and each opening end of the insertion hole is a slope surface expanding radially
outward toward the opening end.
