Abstract

The preheater consists of a chamber enclosing the lower part of the outflow ends of the bundle of inverted U-tubes through which the primary coolant flows. To reduce chemical stresses due to thermal shock, the secondary fluid is fed in at a front on the side of the preheater section such that all or part of the inlet flow to the main chamber of the heat exchanger is in the same general direction as that of the primary fluid in the U-tubes where they pass through the preheater. A number of baffle plates deflect the flow so that it crosses the tubes several times.
