Abstract
A nested-tube heat exchanger with tubes (1) secured at each end in tube plates (3 & 4) for transferring heat between a hot gas that flows through the tubes (1) and a liquid or vaporous contact that flows around the pipes. The tube plates are secured to a jacket (2) that surrounds the nest of tubes. One of the tube plates has parallel cooling channels (7) in the half that faces away from the jacket with coolant flowing through the cooling channels. The tube plate has bores (15) that open into the jacket, communicate with the cooling channels, and concentrically surround the tubes. The tube plate that has the cooling channels is at the gas-intake end of the heat exchanger. The tubes in each row extend through cooling channels. The base (12) of the cooling channels on the side that is impacted by the gas is uniformly thick.
