Abstract
Safety devices prevent packaged catalytic converters from being expelled from stacks, or at least reduce the velocity with which such a package may be expelled, in case of an explosion in a bio-fueled appliance, such as a wood-burning stove.
Claims8
A safety device for a catalytic converter, the safety device comprising:
- a smoke pipe configured to be attachable to an exhaust from a bio-fuel fired appliance, the smoke pipe having an inlet end and an outlet end and comprising a wall defining a plurality of apertures therethrough, the plurality of apertures being longitudinally spaced apart from the outlet end of the smoke pipe, wherein the smoke pipe includes an inside wall defining an interior;
- at least one first bar attached to the smoke pipe and extending inward of the inside wall and at least partially into the interior, the at least one first bar being spaced at least 6 inches, as measured along a longitudinal axis of the smoke pipe, downstream of its nearest aperture;
- and
- at least one second bar attached to the smoke pipe and extending inward of the inside wall of the smoke pipe and at least partially into the interior, the plurality of apertures being between the first at least one bar and the second at least one bar, as viewed along the longitudinal axis of the smoke pipe, the at least one second bar being spaced at least two feet, as measured along the longitudinal axis of the smoke pipe, away from its nearest aperture.

- a smoke pipe comprising an inside wall and that defines an interior;
- at least one first bar attached to the smoke pipe and extending inward of the inside wall and at least partially into the interior;
- at least one second bar attached to the smoke pipe and extending inward of the inside wall and at least partially into the interior, the at least one second bar being disposed a distance, as measured along a longitudinal axis of the smoke pipe, away from the at least one first bar;
- and
- at least one third bar attached to the smoke pipe and extending inward of the inside wall and at least partially into the interior, the at least one third bar being disposed between the at least one first bar and the at least one second bar and laterally off-center within the interior.
