Abstract
An ignition burner for igniting fuel oxygen-containing gas mixture. The burner utilizes a central electrode and means for supplying the electrode with both a low velocity flow and a high velocity flow of combustible gases to the electrode to form a first flame. The first flame is surrounded by a plurality of nozzles that supply additional fuel and oxygen-containing gas to form a large ignition flame.
Claims6
An ignition burner for use in start-up operations comprising:
- a cylindrical housing;
- a tubular element, having one end open for defining a flame port and disposed concentrically within said housing;
- an annular front wall, said annular front wall extending from the cylindrical housing to the tubular element, said annular front wall in addition having an outlet means for oxygen-containing gas and fuel;
- conduit means, said conduit means being disposed in the space between the housing and tubular element to separately supply fuel and oxygen-containing gas to said outlet means in the annular front wall;
- an elongated electrode disposed concentrically in said tubular element and having an uninsulated end adjacent said flame port;
- means communicating with the annular space between said electrode and tubular member for supplying a combustible gas mixture to said annular space;
- a baffle assembly disposed in said annular space adjacent the uninsulated end of the electrode, said baffle assembly having a first passage means for supplying a low velocity flow of said combustible gas mixture to the uninsulated end of said electrode, and a second passage means for supplying a high velocity flow of said combustible gas mixture to the uninsulated end of the electrode;
- and
- flame detector means disposed in said tubular member for detecting a flame present in said outlet means.
