ABSTRACT:
A catalytic bed has an upright forward surface openly exposed to the living space and generates a partially laminar flow and a partially turbulent flow of substantially smokeless gaseous combustion products upward along the bed surface, with laminar flow adjacent thereto and the turbulent flow positioned forward thereof. A collection chamber is positioned above the bed and has spaced apart lower and upper walls to define a rearward collection chamber and a forward inlet space. A negative pressure source is connected to the collection space to create an exhaust flow therefrom. A baffle wall extends laterally and projects upwardly from the lower wall toward the upper wall, terminating at a distance therefrom to create a pressure drop between the collection and inlet spaces sufficient to provide a substantially uniform draw along the length of the baffle wall. The upper wall projects forward beyond the bed surface and downward to define an opening to the inlet space, with the forward projection being beyond the turbulent flow so that the inlet opening captures therein both the laminar and turbulent flows when rising under their natural buoyancy and draws in from the living space under the influence of the pressure source a curtain flow of air from the living space forward of the turbulent flow to block escape of the turbulent flow.
