Abstract
An improved flue gas cooler, or bank of coolers, handles flue gas G from aluminum reduction cells in an aluminum smelter plant. Each flue gas coolerhas a gas inlet chamber, a gas outlet chamber, and a matrix of gas cooling tubesextending between the inlet chamber and the outlet chamber. Each cooling tubehas a bell-shaped inlet endcomprising an aerodynamically curved gas-accelerating profile effective to facilitate streamlined flow of flue gas G into the tube. The improved flue gas cooler makes it possible to connect the flue gas cooler to receive flue gas G direct from the aluminum reduction cells without getting clogged by dust and sublimates present in the flue gas.
