| 摘要 |
The improved inshot burner cluster apparatus of the present invention functions to provide combustion of a gaseous fuel and air mixture which is injected throu gh 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 inter- joined 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.
