ABSTRACT:
An improved reheater for a moisture separator reheater is provided with a header having first and second baffles disposed therein, dividing the interior of the header into inlet, recirculation and outlet flow chambers. The improved reheater also includes two bundles of U-shaped tubes communicating with the header via a tube sheet. Each tube of the first bundle communicates with the header at the inlet and recirculation chambers. Each tube of the second bundle communicates with the header at the recirculation and outlet flow chambers. This arrangement effects a four-pass recirculation of reheating fluid through the improved reheater. Drains are provided at both the recirculation and outlet flow chambers to prevent condensate flooding and any resulting thermal cycling and rupture of the tubes.
