Apparatus and method for blocking flame and spreading heated gas from a broiler flue

摘要

Apparatus for substantially blocking flames and spreading heated gases emitted from a broiler flue. The apparatus includes a riser placed above the broiler flue for defining a pathway along which heated gases are exhausted from the flue, a catalyst support on the riser for supporting a catalyst in the pathway for flow of heated gases through the catalyst from a bottom surface of the catalyst to a top surface of the catalyst, and a plurality of baffles in the riser extending across the pathway below the catalyst support. The baffles have the shape of inverted troughs.

1. Apparatus for substantially blocking flames and spreading heated gases from a broiler flue, said apparatus comprising
a riser adapted to be placed above the broiler flue for defining a pathway along which heated gases are exhausted from the flue, a catalyst support on the riser for supporting a catalyst in the pathway for flow of heated gases through the catalyst, and a plurality of baffles in the riser extending across the pathway below the catalyst support, said baffles having the shape of inverted troughs for substantially blocking flames emitted from the broiler flue and for spreading heated gases exhausted from the flue for more uniform distribution of the heated gases across a bottom surface of the catalyst, the plurality of baffles comprising a first baffle, a second baffle, and a third baffle, wherein the second baffle is centered between the first and third baffles, wherein the second baffle is spaced from the first baffle and the third baffle by a horizontal distance D1 in the range of 0.25-1.0 in. to provide a horizontal gap sufficiently small to substantially block said flames but sufficiently large to allow flow of said heated gases to the catalyst without an excessive pressure drop; and wherein the second baffle is larger in cross-sectional height and width than the first and third baffles.
