FIELD: metallurgy. ^ SUBSTANCE: stack gas cooler has gas intake and gas discharge chambers and a matrix of gas-cooling pipes, extended between gas intake chamber and gas discharge chamber. Each gas-cooling pipe has a bell-shaped inlet end with an aerodynamically curved profile for acceleration of gas and facilitation of laminar flow of stack gas G into the pipe. Method of stack gas cooling and cleaning is also disclosed. ^ EFFECT: ability to receive hot unprocessed stack gas G directly from aluminium pots without causing clogging of cooler by dust and sublimates present in the stack gas. ^ 16 cl, 3 dwg, 4 ex, 1 tbl |
