摘要:
A starting device for reformed gas generators of the type in which atomized or evaporated liquid, hydrocarbon containing fuel is catalytically reacted with a gas containing oxygen at elevated temperatures to form a fuel gas, includes a conically shaped housing having an outlet for coupling to the inlet of the reformed gas generator, a gas permeable burner plate within said housing, a fuel injection nozzle arranged so that nearly the entire surface of the burner plate is supplied with fuel, a heat-resistant, gas permeable terminating plate filling, the outlet of the starting device and defining, with the burner plate, a combustion chamber, an ignition device disposed in said combustion chamber and means for introducing the air and atomized fuel into the combustion chamber through the burner plate.
摘要:
A gas generator which comprises a heat resistant housing and a reaction chamber which is centrally arranged therein and contains a catalytic charge, with an inlet opening for the reactants and an outlet opening for the fuel gas is used for catalytically reacting liquid, hydrocarbon containing fuel to be evaporated with an oxygen containing gas at elevated temperature to form a fuel gas. The housing consists of a lower part and a removable cover and the reaction chamber including the catalytic charge is replaceable. The fuel and/or the oxygen containing gas is fed to the reaction chamber for preheating and evaporating, respectively, via a system of tubes which is arranged between the reaction chamber and the lower part of the housing and is run around the reaction chamber in helical fashion.
摘要:
A device for distributing flowing media over a flow cross section comprising a distributor plate extending over the flow cross section and having a multiplicity of openings over its entire extent. The device further includes a cover plate having passages distributed over its entire extent and movably arranged relative to the distributor so as to be able to determine the free passage cross section of all the openings of the distributor plate. The device can be arranged advantageously, at the input of a reaction chamber with a catalytic charge, in order to distribute the reactants over the cross section of the catalytic chamber.
摘要:
The invention concerns preventing oxidation of printed circuit board metal surfaces as a result of heat produced in a solder bath arrangement and reducing thermal stress defects from occurring in the circuit carrier being soldered. An enclosed reaction chamber is provided with the solder bath and supplied with a pressurized atmosphere of inert gas which gas seals the reaction chamber from ambient air. The inert gas is discharged from jets against the solder side (the connector post side) of the printed circuit boards at a point upstream of the solder bath and the inert gas is at a temperature substantially higher than the solder bath temperature.
