    摘要： Two improvements for heaters are disclosed which can be implemented as either apparatus or method. First is a novel flue gas injection system. Second is a novel burner configuration. The improvements can be used alone or together. In the flue gas injection system, flue gas is injected between the burners and the tubes to reduce heat flux on the tubes and shift part of the heat duty from the radiant to the convective section. These approaches work toward increasing the capacity of heaters where we can increase the firing rate in the heater and still keep the tube metal temperature and radiant fluxes within acceptable limits.

    摘要翻译： 公开了加热器的两个改进，其可以作为装置或方法来实现。 一是新型烟气注入系统。 二是新型燃烧器配置。 这些改进可以单独使用或一起使用。 在烟气注入系统中，烟道气被喷射在燃烧器和管之间，以减少管道上的热通量，并将部分热负荷从辐射部分转移到对流部分。 这些方法致力于提高加热器的容量，在那里我们可以增加加热器中的燃烧速率，并且仍然保持管金属温度和辐射通量在可接受的限度内。

    摘要： A flat flame burner comprises an air swirling chamber, an air supply tube provided for the air chamber for introducing combustion air thereinto in the peripheral direction of the air chamber so as to produce a swirling air stream in the chamber, a fuel gas supply tube disposed in the air chamber and having inlets centrally of the space for the swirling air stream and a flame opening positioned at one side in the direction of axis of the swirling air stream coaxially with the swirling air stream, the flame opening being defined by a wall having a thin portion around said opening and a flat outer face.

    摘要： An oxy-fuel burner arrangement having a first conduit having a nozzle aperture with an aspect ratio, D1/D2, of greater than or equal to about 2.0. The first conduit is arranged and disposed to provide a first fluid stream, where the first fluid stream is a combustible fuel. The burner arrangement further includes at least one second conduit arranged and disposed to provide a second gas stream circumferentially around the first fluid stream, where the second gas stream includes oxygen. A precombustor is arranged and disposed to receive the first fluid stream and second gas stream where an oxy-fuel flame is produced. The geometry of the nozzle aperture and the cross-sectional geometry of the first conduit are dissimilar.

    摘要： A burner assembly having improved flame length and shape control is presented, which includes in exemplary embodiments at least one fuel fluid inlet and at least one oxidant fluid inlet, means for transporting the fuel fluid from the fuel inlet to a plurality of fuel outlets, the fuel fluid leaving the fuel outlets in fuel streams that are injected into a combustion chamber, means for transporting the oxidant fluid from the oxidant inlets to at least one oxidant outlet, the oxidant fluid leaving the oxidant outlets in oxidant fluid streams that are injected into the combustion chamber, with the fuel and oxidant outlets being physically separated, and geometrically arranged in order to impart to the fuel fluid streams and the oxidant fluid streams angles and velocities that allow combustion of the fuel fluid with the oxidant in a stable, wide, and luminous flame. Alternatively, injectors may be used alone or with the refractory block to inject oxidant and fuel gases. The burner assembly affords improved control over flame size and shape and may be adjusted for use with a particular furnace as required.
