Radiant gas burner assembly

Abstract From the Canadian patent

A gas fired radiant griddle assembly employing a series of perforated ceramic tiles to define a burner surface positioned beneath the griddle. The center area of the assembled ceramic tiles is blocked off so as to define an annular burner surface to minimize the temperature gradient across the griddle surface and the hot combustion effluents are drawn by convection beneath the griddle surface and out the rear corners of the combustion chamber beneath the griddle to heat the peripheral and corner portions of the griddle and further minimize the temperature gradient across the expanse of the griddle.
