摘要:
A burner for a heater, especially for motor vehicles, has an essentially axially symmetrical combustion chamber, a burner nozzle for supply and atomization of fuel, a fuel needle for supplying fuel to the combustion chamber, a combustion air supply for supplying combustion air to the combustion chamber, a starting zone in which ignition of the fuel to start the burner takes place, a heat shield between the burner nozzle and the combustion chamber, the heat shield having openings for supplying secondary air to the combustion chamber, and a baffle plate located in the combustion chamber. By choosing the inside diameter of the fuel needle, the exit speed of the fuel is predetermined such that, during the starting phase of the burner; fuel in essentially unatomized form reaches the starting zone. The openings have air guide elements, and the baffle plate has a defined curvature in the axial direction.

A combustion system includes a perforated flame holder, an oxidant source, and an adjustable fuel nozzle. The oxidant source outputs oxidant. The adjustable fuel nozzle outputs fuel onto the perforated flame holder. The perforated flame holder supports a combustion reaction of the fuel and oxidant within the perforated flame holder. The position of the adjustable nozzle relative to the perforated flame holder can be adjusted to achieve selected characteristics of the combustion reaction within the perforated flame holder.

The present invention relates to a catalytic combustion device comprising a main combustion zone (20, 200) including at least one catalytic section (5, 103) and at least one air/fuel mixing zone (11, 117), said mixing zone comprising at least one pressurized air inlet (1, 101) and injection means (12, 105) for injecting a liquid fuel. According to the invention, injection means (12, 105) project the liquid fuel onto a hot wall (13, 15, 107) of said device so as to allow vaporization of said fuel on contact with this wall.

In an apparatus comprising a chamber (3) of a reactor drops (8) of a to be converted liquid are generated by a nozzle (2) positioned in a space (7) separate from the chamber (3). The drops (8) make a free fall thought the space 7 and enter via an opening (7a) the chamber (3) where they fall onto an evaporator body (9) for evaporation, the evaporated liquid leaves a solid deposit (1), A gaseous reactant line (11) supplies a reactant gas for conversion of the solid deposit (1) on the surface of the evaporator body.

A compact burner-boiler combination having an improved heating cycle for effecting substantial fuel saving and maximum boiler and combustion efficiency in a relatively simple and expedient manner. This is attained by a compact boiler construction utilizing an improved burner construction and method of combustion in which a liquid fuel is gasified by the heating products of combustion to form a homogeneous fuel gas-air mixture prior to combustion so as to effect a substantially stoichiometric burning of the fuel so as to result in a high velocity and a very high flame temperature (approx. 4100.degree. F.) and to cause the breakdown of a portion of the hydrocarbons into their basic component elements so as to make them available for diffusion burning. A small percentage or air is thereafter introduced tangentially into the burner flame to create the diffusion burning of the free hydrogen and carbon generated by the combustion process to produce a hot luminous optimum flame pattern and to maintain the high surface velocity so as to attain maximum transfer of heat energy to the heat transfer surfaces of the boiler by both radiation and conduction.

A burner (10) for a heater, especially for use in motor vehicles, with an essentially axially symmetrical combustion chamber (22) and a baffle plate (36) which is located in the combustion chamber. The baffle plate (36) has a defined curvature in an axial direction and that there is a curvature in the direction of the burnout zone (32). An outer periphery of the baffle plate defines a plane and a maximum axial distance of the baffle plate from this plane Dm and the diameter of the baffle plate Bd have dimensions that have a ratio Dm:Bd relative to each other that is between 0.07 and 0.21.
摘要:
A dual phase fuel vaporizing combustor, and method for burning, in an annular vaporizing combustor, high viscosity, high carbon/hydrogen ratio hydrocarbon fuels, including such as residual fuels, low grade synfuels and coal-oil slurries. A dual phase vaporizer tube receives alternating introductions of a fuel air mixture of high fuel content, and then a hot air or low fuel content mixture, to alternately initially discharge from the tube a vapor stream of combined air and partially vaporized fuel, the initial vapor stream impinging onto a hot surface where more volatile portions of fuel will vaporize and burn, while less volatile heavier fuel components will form a hot carbon deposit on the surface; and alternately and sequentially discharge from the tube a hot, highly oxidizing stream with little or no fuel and impinge the sequential stream onto the carbon deposit on the hot surface and thereby promote substantial burning of the carbon.
