ABSTRACT:
This invention provides a method and apparatus for exhausting rising fume from a fume-producing apparatus into a hood opening located above but laterally displaced from the fume-producing apparatus. A first jet producing a moving curtain of air is directed generally across the fume-producing apparatus from the side thereof which is remote from the hood, with the curtain at least wide enough to span substantially the whole of the rising fume. A second jet produces a second moving curtain of air travelling generally upwardly toward the hood opening from a position spaced generally beneath that opening. The energy and direction of the first jet and the resultant air curtain are such that, if the second jet were not present, the resultant paths for all portions of the air/fume mixture would traverse the general region between the hood opening and the position of which the second jet originates.
