    摘要： A heating method for heating vessels, the vessels having enclosed spaces therein and controlling air ingress into the enclosed spaces through gaps. The method includes providing a lid structure for the vessel having the enclosed space, the lid structure having a burner assembly mounted therein. The burner is configured to provide a predetermined flame diameter. The vessel and lid structure are mated such that the gap is formed between the vessel and the lid structure. Fuel and oxidant are discharged from the burner assembly under conditions to provide the predetermined flame diameter and impart a flame velocity sufficiently large to create an outward gas flow from the enclosed space through the gap and control air ingress.

    摘要： A symmetric device for stabilization of a flame includes a primary oxidant pipe and a fuel pipe. The fuel pipe is internal to the primary oxidant pipe creating a primary oxidant conduit. A secondary oxidant pipe is internal to the fuel pipe creating a fuel conduit. A primary oxidant source supplies oxidant to the primary oxidant conduit. A fuel source supplies fuel to the fuel conduit. A secondary oxidant source supplies oxidant to the secondary oxidant pipe. The first oxidant velocity is greater than the second oxidant velocity and the fuel velocity is less than the second oxidant velocity. The primary oxidant pipe end extends past the fuel pipe forward end and the fuel pipe forward end extends past the secondary oxidant pipe end. A mismatch in velocity between fuel and oxidant generates a large scale vortex. An asymmetric embodiment is also provided.

    摘要： An oxy-fuel furnace and method of heating material in an oxy-fuel furnace are disclosed. The method includes combusting oxygen and fuel with an oxy-fuel burner arrangement in the oxy-fuel furnace forming combustion gases, and maintaining a vortex including the combustion gases within a central region of an enclosure of the oxy-fuel furnace. The oxy-fuel burner arrangement includes a plurality of high momentum oxy-fuel burners arranged at an angle to generate the vortex, the angle being greater than 15 degrees but less than 75 degrees with respect to a furnace wall boundary of the enclosure, an angular velocity of greater than 0.07 radians per second, or a combination thereof. The furnace includes an oxy-fuel burner arrangement including at least two high momentum oxy-fuel burners having high shape factor nozzle geometries, and an enclosure. The vortex increases convective heating within the enclosure and uniformity of heating within the enclosure.

    摘要： A method of combustion and a reformer. The method includes combusting a fuel in a combustion region of an up-fired or down-fired reformer and forming non-uniform injection properties with a wall-bound burner. The combusting is performed in a combustion region by burners, wherein at least one of the burners is the wall-bound burner forming the non-uniform injection properties. The non-uniform injection properties generate a heat profile providing a first heat density proximal to a wall and a second heat density distal from the wall, the second heat density being greater than the first heat density. The non-uniform injection properties are formed by injection properties selected from an angle of one or more injectors, a flow rate of one or more injectors, an amount and/or location of oxidant injectors, an amount and/or location of fuel injectors, and combinations thereof.
