An industrial burner in which gaseous fuel is supplied to a mixing and combustion zone within a burner body by way of a conical distribution manifold formed with annular rows of gas discharge ports. A separate passage for pilot gas is formed through the manifold and terminates as an isolated pilot port which discharges a jet of pilot gas for establishing a pilot flame uses to ignite the main gas. Combustor plates surround the gas manifold and are formed with air passages which are so angled and so located as to form canopies of air jets over the fuel jets, the air jets intersecting each other at a significant distance from the center line of the burner.
