摘要： A burner having lower emissions and lower unburned fuel losses by providing a transition zone to act as a buffer between the primary and secondary air streams. The transition zone provides improved control of near-burner mixing and flame stability by providing limited recirculation regions between primary and secondary streams. These limited recirculation regions transport evolved NOx back towards an oxygen-lean pyrolysis zone for reduction to molecular nitrogen.

摘要： A burner design for use especially with rotary dryers is provided, in which a primary firing tube is provided with an oil body disposed proximate the burner tip portion of the firing tube, the oil body being constructed to divide an airflow into an outer portion flowing through an outer airstream passageway and an inner portion flowing through an inner airstream passageway, and to cause said inner and outer portions to intersect each other proximate the burner tip portion. The oil body is further provided with a slit opening on an inner surface thereof along a boundary of the inner airstream passageway, the slit opening being in fluid communication with a supply of fuel oil, whereby fuel oil can be delivered at low pressure at an inner surface of the oil body, whereupon the inner airstream portion will cause the fuel oil to film along the inner surface of the oil body and to be intersected by the inner and outer airstream portions to atomize the fuel oil at the burner tip. A secondary air body surrounds one or more primary firing tubes and provides air to the firing tubes for a fuel/air premix, and provides swirling air surrounding the primary firing tube at the burner tip portion.
摘要翻译：提供特别用于旋转干燥器的燃烧器设计，其中初级燃烧管设置有靠近燃烧管的燃烧器末端部分设置的油体，油体构造成将气流分成流过的外部部分外部气流通道和内部气流通过内部气流通道，并使所述内部和外部部分在燃烧器末端部分附近相互交叉。油体在其内表面上还沿着内气流通道的边界设置有狭缝开口，狭缝开口与燃料油流体连通，由此燃料油可以在内部的低压下输送因此内部空气流部分将导致燃料油沿着油体的内表面成膜并与内部和外部气流部分相交以雾化燃烧器尖端处的燃料油。二次空气体围绕一个或多个初级发射管并且向用于燃料/空气预混合物的燃烧管提供空气，并且在燃烧器尖端部分处提供围绕主燃烧管的旋转空气。

摘要： A burner assembly (10) is provided for combining oxygen and fuel to produce a flame (44). The burner assembly (10) includes a burner block (12) formed to include a flame chamber (32) having inlet and outlet openings (34, 36), a bypass passage (126) for conducting oxygen outside of the flame chamber (32), and a mechanism (20) for discharging fuel into the flame chamber (32) formed in the burner block. An oxygen-supply housing (16) includes a base wall (52) adjacent to the burner block (12) and a chamber (56) for receiving a supply of oxygen. The base wall (52) is formed to include a first aperture (66) for discharging oxygen from the chamber into the flame chamber and at least one second aperture (68) for discharging oxygen from the chamber (56) into the bypass passage (126).
