ABSTRACT:

The invention provides 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 wherein 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 wherein the integrated gas burner comprises a burner module and a gas train 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 wherein the perforated screen is positioned upline to the burner face to increase combustion; and 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;
    and an appliance comprising the integrated burner.
