<p>Natural gas burner has axial blower for blowing air into burner nozzle. The primary combustion air is set into rotation by fixed swirler blades downstream of the blower to ensure good mixing of gas and air. The flame tube (H) made from steel plate tapers in downstream directions, and on the downstream end accommodates gas mixing tube (G). An igniting electrode generates an igniting spark. Downstream of blower (F) are arranged swirler blades. The swirling air meets downstreams a baffle plate where air pressure is increased. This plate is held on gas mixing tube.</p> |
