Abstract: The present invention relates to an apparatus for barbecue grilling of food comprising an outer housing (1) having a grill (2) upon which food can be placed, a radiant heat source (3) located below the grill (2), and a supply (4) of combustible gas and air mixture to heat the radiant heat source (3). The radiant heat source (3) comprises a chamber located within the outer housing, the inner chamber (3) being spaced from the outer housing (1) to define an air passage (9) and wherein a supply of pressurized air flows in the air passage (9), the pressurized air providing a primary source of air for mixing with the combustible gas and a secondary source of air which passes into the inner chamber (3) thereby increasing oxidizing conditions within the inner chamber.
