摘要: Vapor generators for powering external combustion engine systems. Their combustor generates heat in full response to engine system power demands. Emissions have low noxious pollutant content over the wide power demands of a vehicle on the road. Internal arrangements maximize combustion of the fuel that is atomized in the primary combustion zone. Hot spots above 2,100* F in the combustor are minimized to inhibit the formation of nitrous oxide. Further, quenching spots below 1,500* F are controlled to minimize the formation of carbon monoxide and unburned hydrocarbon particles. An important feature in the combustor section is that the direction of flow of input air is opposite to that of the flow of the hot combusted gases. This moderates the rate of gas flow, and turbulates to intermix the gases towards their complete combustion. A wide range of available fuels may be used, and operation over at least a 20:1 range of air to fuel input is effected. The combustor-vapor generator hereof meets the Emission Standards for 1976 set by the Environmental Protection Agency. It is suitable for mass production at reasonable unit cost with relatively inexpensive materials.

摘要: Reigniter means for combustors of vapor generators used in eternal combustion engine systems. The combustors provide heat in response to engine power demand to vaporize liquid in boiler tubes. Combustion emissions are with low noxious pollutant content over the power operating range of the engine system. Internal arrangements in the combustors maximize burning up of fuel that is injected into the primary combustion zone. Portions of the combustor that may reach above 2,100*F are minimized to inhibit the formation of nitrous oxide. Regions that might fall below 1,500*F are controlled to minimize quenching that would result in the formation of carbon monoxide and unburned hydrocarbon particles. The flow of combusted gases is moderated by arranging incoming air to be in the counter direction. Air and fuel particles are thoroughly intermixed towards complete combustion. An important feature is a tower positioned in the route of the gases out of the combustor, for reigniting combustible particles that have not fully burned.

摘要: The vapor generators are for powering external combustion engine systems. The combustors thereof provide heat in response to engine power demand to vaporize liquid in their boiler tubes. Their combustion emissions are with low noxious pollutant content over the power operating range of the engine system. Internal arrangements are incorporaed in the combustors that maximize burning-up of fuel that is injected into the primary combustion zone. Portions of the combustors that may reach above 2,100* F are minimized to inhibit the formation of nitrous oxide. Regions that might fall below 1,500*F are controlled to avoid quenching that would result in the formation of carbon monoxide and unburned hydrocarbon particles. The flow of combusted gases is moderated by arranging for the flow of incoming air to be in the counter direction. Air and fuel particles are thoroughly intermixed towards complete combustion. A wide range of available fuels may be used, and operation over at least a 20:1 ratio of fuel input is effected. An important feature hereof is the use of a flat spiral wall of fluid filled tubing above the combustion zones. Fluid to be vaporized flows through the fluid tube wall, and shields the combustor housing from reaching excessive temperature.
