Abstract
The improved inshot burner cluster apparatus of the present invention functions to provide combustion of a gaseous fuel and air mixture which is injected through an aperture in the inlet plate into the combustion compartment of a heat exchanger, and includes a burner cluster which may have a selected multiplicity of burners formed from an interjoined upper half shell and a lower half shell. The modular, and essentially clam-shell, form of construction allows for ease of forming the burner elements by embossing the sheet metal half shells, for example using a progressive type of punch press die which can thereafter cut-off any number of burners to form a burner cluster.
Claims18
An improved inshot burner cluster for use in association with an induced draft combustion heat exchanger, said inshot burner cluster comprising:
- an upper burner half shell unitarily formed of a sheet of an embossable metallic material, said upper burner half shell having a plurality of longitudinal upper burner halves of corresponding inshot burners embossed thereunto in spaced array thereon;
- a lower burner half shell unitarily formed of a sheet of an embossable metallic material, said lower burner half shell having a plurality of longitudinal lower burner halves of corresponding inshot burner embossed thereinto in spaced array thereon;
- and
- and means for securing said upper burner half shell to said lower burner half shell with said respective longitudinal upper and lower halves of said plurality of inshot burners in registered alignment to form thereby a plurality of spaced inshot burners.
