Abstract
Abstract A shell is formed into a housing for an industrial burner which is connected to the end of a firetube into which the products of combustion from the burner are discharged. A sub-housing has a flame arrestor element mounted on its external surface and is connected to the burner housing to form a path for all combustion air.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
159 words
A mounting and housing for an industrial fluid fuel burner, including, a first housing within which a fluid fuel burner may be mounted to discharge products of its combustion from a first opening of the housing, a burner mounted within the housing at a position where its controls for fuel and air are readily accessible through a second opening of the housing, means for removably connecting the housing to the end of a firetube so that the products of combustion are discharged into the firetube through the first opening, a second housing removably connected over the second opening of the first housing and itself having two of three openings through which air flows for combustion, means for removably sealing a first of the openings of the second housing, and a screen-like flame arrestor mounted on the external surface of the second housing and adjacent the second opening so combustion air will flow through it and into the second opening.
Claim 2
Dependent Claim
159 words
A mounting and housing for an industrial fluid fuel burner, including, a first housing within which a fluid fuel burner may be mounted to discharge products of its combustion from a first opening of the housing, a burner mounted within the housing at a position where its controls for fuel and air are readily accessible through a second opening of the housing, means for removably connecting the housing to the end of a firetube so that the products of combustion are discharged into the firetube through the first opening, a second housing removably connected over the second opening of the first housing and itself having two of three openings through which air flows for combustion, means for removably sealing a first of the openings of the second housing, and a screen-like flame arrestor mounted on the external surface of the second housing and adjacent the second opening so combustion air will flow through it and into the second opening.
Claim 3
Dependent Claim
27 words
The structure of claim 1, wherein, the screen-like flame arrestor is in the form of a continuous element which is wound in layers about the second housing.
Claim 4
Dependent Claim
77 words
The structure of claim 2, wherein, the second housing is in the form of a cylinder, the second opening is in the form of a peripheral slot in the cylindrical wall, and the flame arrestor comprises two separate elements wound on each side of the slot which elements are bridged by a solid band attached to the elements, such seal forcing all combustion air to flow into the housing through the arrestor elements from two different directions.
