<p>An improved flue gas cooler 10, or bank of coolers 10, handles flue gas G from aluminum reduction cells in an aluminum smelter plant. Each flue gas cooler 10 has a gas inlet chamber 14, a gas outlet chamber 16, and a matrix of gas cooling tubes 18 extending between the inlet chamber and the outlet chamber. Each cooling tube 18 has a bell-shaped inlet end 19 comprising 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.</p> |
