Estimating the term…
A burner module that can be used in combusting an air/fluid fuel flow is described. The burner module may be incorporated in an appliance. The burner module comprises a burner face comprising catalytic material for combusting the air/fluid fuel flow and a perforated screen having a plurality of micro-perforations where the perforated screen is positioned upline to the burner face to increase combustion; an integrated gas burner for connection to a pressurised fluid fuel flow where the integrated gas burner comprises a burner module and a gas train. The gas train comprises (a) an ejector for entraining air with the fluid fuel flow; and (b) a diffusor for converting the air/fluid fuel flow kinetic energy into pressure and for performing flow expansion.
A burner module for use in combusting an air/fluid fuel flow wherein the burner module comprises a burner face comprising catalytic material for combusting the air/fluid fuel flow and a perforated screen having a plurality of micro-perforations and the perforated screen is positioned upline to the burner face to increase combustion, wherein the perforated screen is formed from a material having a thermal conductivity adapted to reduce thermal bridging from the burner face and reflect incident heat radiation in a direction substantially perpendicular to the burner face.
A burner module as defined in any one of the preceding claims which comprises at least two perforated screens upline of the burner face wherein the perforated screens comprise a throttling perforated screen and a homogenisation perforated screen wherein the perforations on the throttling perforated screen are selected to provide a predetermined degree of aeration of the air/fuel mixture;
A burner module as defined in any one of the preceding claims wherein the plurality of perforations of the one or more perforated screens are shaped to increase spill resistance and/or noise attenuation.
A burner module as defined in any one of the preceding claims wherein the perforations have a cusp.
A burner module as defined in any one of the preceding claims wherein the perforated screen comprises a foil material or a metallic foil.
A burner module as defined in any one of the preceding claims wherein the perforated screen is polished to reduce heat transfer to the gas train and consequent generation of temperatures at a surface confining the flow of air/fuel mixture which are high enough to initiate light-back.
A burner module as defined in any one of the preceding claims wherein the perforated screen is shaped to provide one or more supports for the burner face.
A burner module as defined in any one of the preceding claims wherein the perforated screen has one or more ribs to provide axial stiffness.
A burner module as defined in any one of the preceding claims which comprises a crimp ring for attaching the burner module to a gas train.
A burner module as hereinbefore described and/or illustrated with reference to the Figures of the accompanying drawings.
An integrated burner substantially as hereinbefore described and/or illustrated with reference to one or more of the Figures of the accompanying drawings.
An appliance substantially as hereinbefore described and/or illustrated with reference to one or more of the Figures of the accompanying drawings.
