专利汇可以提供Cyclonic multi-fuel burner专利检索，专利查询，专利分析的服务。并且This disclosure describes an apparatus that will burn all types of liquid and gaseous fuels or combinations thereof by an improved method that results in greater efficiencies, stability and control. The simple approach in solving the present problems of burning specific fuels has resulted in a very versatile unit suitable for numerous uses and specifically applicable to burn asphaltic fuel compounds such as pitch and 10 pen Asphalt. The disclosure describes an improved heat exchanger to superheat the atomizing medium and the sonic and/or subsonic vortex of the primary atomizing zone assisted by multiple impingement points and cylconic turbulence and low pressure within the diffuser resulting in micron size droplets of fuel that easily vaporize and greatly improve the reaction process to produce a very efficient flame with fuels ranging down to 3* API.，下面是Cyclonic multi-fuel burner专利的具体信息内容。

权利要求

1. A burner assembly comprising, in combination, inlet and outlet manifolds, an annular heat exchanger defined by inner and outer walls interposed between and in communication with said manifolds, one wall of said heat exchanger defining a combustor section whereby an atomizing medium flowing through said heat exchanger is heated by transfer of heat from said combustor section through said one wall prior to introduction to an atomizing means, atomizing means for imparting a high velocity tangential vortex to the atomizing medium to react it longitudinally and tangentially on a fuel for aerodynamically mixing the heated atomizing medium intimately with a fuel within said combustor section and to produce molecular shear in the fuel resultant in an atomized fuel having substantially micron size droplets.

2. The burner assembly defined in claim 1 wherein said heat exchanger is packed with a discrete heat conductive material having a shape aiding in the transfer of heat from the said combustor defining wall outwardly into the annulus defined by said walls to impart turbulence to the atomizing medium flow therethrough and thus improve the efficiency of the heat absorption by the medium.

3. The burner defined in claim 1 including, in addition, air register means spaced from but in communication with said combustor section, a gaseous fuel injector ring positioned adjacent the inlet end of said combustor section and interposed between said combustor section and said air register means, said injector ring having spaced parts therein directed inwardly from the vertical whereby the kinetic energy of the fuel gas jets inspirates the primary air for combustion.

4. The burner assembly as defined in claim 1 wherein said atomizing means is centrally located at a point within said combustor so that the atomized fuel is injected in an area where the flame front will be stabilized, said atomizing means comprising an outer conduit in communication with an atomizing head and defining a conduit for the atomizing medium to enter said atomizing head, a fuel tube positioned interiorly of said atomizing medium conduit and extending within said atomizing head to a point wherein a portion of said head and said tube cooperAtively define a fuel nozzle, vortex generating means interposed between said atomizing medium conduit and said fuel nozzle and communicating with a vortex cavity defined by a portion of said atomizing head between said vortex generating means and said fuel nozzle, the fuel thus being atomized by the high velocity vortex generated atomizing medium in the area downstream of said nozzle.

5. The burner assembly as defined in claim 4 wherein said vortex generating means includes a swirl plate interposed between said atomizing medium conduit and the area downstream of said fuel nozzle and opening to the vortex cavity said swirl plate having at least one vortex generating channel therein positioned to cause flow tangentially opposite to the natural vortex.

6. The burner assembly as defined in claim 4 wherein a portion of said fuel nozzle which defines the vortex cavity downstream of said vortex generating means defines a transition section decreasing in area until the fuel exit nozzle is formed between the atomizer head and the fuel tube upstream of a diffuser section.
