Abstract:
Clean hydrocarbon fuel (30, 30a, 30b) is mixed (41, 41a, 41b) with water (13) and fed to an inner inlet (49) of an atomizing nozzle (53), an outer inlet (56) of which receives compressed air (59), the atomizing nozzle being within a vaporizer (54) at the inlet of an autothermal reformer (79). The fuel is desulfurized (30, 30a). Mixers include high shear (41), mechanical agitation (41a) or static (41b). A gas assist nozzle (49a) may be used.
Abstract:
The invention comprises a method and apparatus for burning combustible fluids, such as biofuel byproducts and feedstocks, which are difficult to burn in a stable and clean manner. The method includes preheating the combustion zone prior to initiating flow of the combustible fluid and maintaining a minimum oxygen concentration in the oxidant gas.
Abstract:
A method and a fuel atomizer (21), for atomizing liquid fuel in a burner (1) for gaseous and liquid fuel wherein the fuel is mixed with an air flow (F) to a fuel mixture for combustion, comprises carrying out the atomization of the liquid fuel through at least one rectilinear fuel atomizer (21), arranged in the burner (1), for spreading a fuel film for atomization. The fuel atomizer (21) gives a local uniform and high air-fuel ratio which results in the burner developing low NOx emissions. The burner (1) preferably consists of a cone-shaped EV burner.
Abstract:
Oil combustion system (10) for burning waste oil in which oil is pumped by an oil transfer pump (16) from an oil reservoir (18) through a bouyant swirling filter (49). The oil is supplied to a high pressure input (50) of a pressure reducing fitting (14) and is transmitted through the fitting (14) to a low pressure output (54) and a high pressure output (52). A siphon nozzle head (12) is operable to siphon the oil from the low pressure output (54) of the fitting (14), to preheat the oil, to atomize the oil and to output the atomized oil. Retention chambers (84 and 88) and heat transfer plugs (42 and 44) within the nozzle head (12) facilitate preheating of the oil and perform a baffle function.
Abstract:
A method for turning an atomizing burner from an ON state to an OFF state is provided. The burner has independently controllable flows of atomizing air, combustion air, and fuel flow, the burner in the ON state having flow values of burner parameters including flow of atomizing air, flow of combustion air, and fuel flow. The method includes: changing, in response to an OFF instruction, flow of at least one of the flow of atomizing air, combustion air and/or fuel to a lower non-zero value; first discontinuing, after a first period of time since the changing, flow of fuel and flow of atomizing air; maintaining, for a second period of time since the first period of time, flow of combustion air; second discontinuing, after the maintaining, flow of combustion air; wherein the maintaining prevents buildup of excess heat inside the burner during the transition to the OFF state.
Abstract:
Method and apparatus for feeding halogenated material to a gasification reactor including supplying a gaseous source of oxygen at supersonic velocity and discharging a liquid halogenated material from at leat one discharge port radially peripheral to discharging oxygen source gas such that the oxygen gas atomizes the liquid halogenated material into the gasification reactor.
Abstract:
Device for mixing gas, liquids or pulverised solid substances with a gas flow (1), whirling (vortex) around an axis in the flow direction. The whirling gas flow is guided through a converging passage (4) and, during or after being charged with the substance, abruptly widens in cylindrical space (11), as a result of which vortex break down occurs and an exceptionally thorough mixing and/or atomizing of the substance is obtained. Application in a burner improves the combustion result, keeps the NOX-values low and prevents the flame from being blown off.
Abstract:
An apparatus and method for burning liquid fuel or atomizing liquid for use in fuel burners or atomizers of the type which comprise a hollow atomizer bulb (20) having a convex exterior surface (22) which tapers toward an aperture (14) through which air atomizes a liquid as it flows in a film over the surface of the bulb. Such atomizer bulbs are located within an atomizing chamber (12) through which a flow of air is directed toward a discharge opening (16, 16') aligned with the aperture (24) of the atomizer bulb. To protect the film of liquid flowing over the bulb, the bulb is enclosed within a shield (54-64).
Abstract:
An improved fuel burner particularly adapted for domestic use and capable of burning fuels such as fuel oil and the like with extremely high efficiency and low pollutant output is comprised of a pair of plenum type atomizers (26, 26'), each having a convex surface onto which the fuel is flowed for atomization, the atomizers (26, 26') being disposed at the end of a flame tube (3) which in turn is located within a blast tube (1), said atomizers (26, 26') further being disposed symmetrically with respect to the axis of both the flame tube (3) and the blast tube (1) whereby the spray output from the atomizers is discharged into the flame tube (3) to create a stable flame front that can be readily ignited by a spark type of ingitor (18). The atomizers are provided with one or more apertures (29') through which atomizing gas is passed to generate the spray, and air access ports (12, 12', 13) are located along the flame tube to provide the necessary air to complete the combustion process.
