Title Infiltration of roof exhaust gases into aluminium potrooms
Bibliographic information Oct. 1983, Vol.33, No.10, p.974-979. Illus. 5 ref.
Abstract Atmospheric tracer techniques were used in 21 tests to determine infiltration rates of roof exhaust gases in downwind potrooms at an aluminium reduction plant during 2 summer months. Tracer concentrations were measured along the ventilation doors of downwind rooms. Maximum infiltration rates were <5% of the tracer release rate. Maximum infiltration occurred along the upwind side of the first downwind room in two-thirds of the cases and along the downwind edge of the same room where tracer was released in one-third of the tests. For rooms further downwind the infiltration rate was <1%.
