Abstract
A gas fired infrared burner includes a burner body with a primary inlet for gaseous fuel and air, the burner body defining a primary premixing chamber for receiving gaseous fuel and air from the primary inlet. An emitter arrangement is configured and positioned such that gaseous fuel and air flows through the emitter arrangement to be combusted at an external surface of the emitter arrangement. The burner body includes an auxiliary inlet for gaseous fuel and air, and the burner body defines an auxiliary premixing chamber for receiving gaseous fuel and air from the auxiliary inlet. The emitter arrangement includes an auxiliary emitter segment that receives gaseous fuel and air from the auxiliary premixing chamber such that combustible gases emitted from the auxiliary emitter segment can be ignited even when no combustible gases are being emitted from portions of the emitter arrangement that are fed from the primary premixing chamber.
