Title: Improvements relating to air-nozzle arrangements for gas generators
IPC: C10J3/80
Filed: 1951-07-04
Abstract: 708,547. Gas producers. DAIMLER-BENZ AKT.-GES. July 4, 1951 [Dec. 20, 1948], No. 15915/51. Class 55 (1). [Also in Group XXVII] An exhaust gas passage is arranged to discharge obliquely in front of but at a distance from a funnel like entry to a gas generator air nozzle in such a manner that when air enters the latter from the outside atmosphere exhaust gases are drawn or blown into the nozzle together with the air but in the event of striking back gas mixture from the nozzle does not penetrate into the passage. Referring to the Figure an air nozzle b of a gas generator a is supplied through a nozzle i with the exhaust gases of an internal combustion engine (not shown) which may be an engine supplied by the gas generator and driving a vehicle. The exhaust gases serve as a cooling medium since they moderate combustion. A pipe h is branched off the engine exhaust pipe e in front of a silencer f and this pipe supplies exhaust gases to the nozzle i which is arranged adjacent the inlet d of the air nozzle. The nozzle i is situated so that gases striking back from the generator cannot pass into the exhaust passage. A non-return valve may be provided in front of the air nozzle passage bo. It is possible to dispense with external cooling of the nozzle or with cooling by a liquid or gaseous cooling medium requiring a cooling jacket. Additional cooling may be provided with the aid of fins c. Cooling by means of a sodium filling surrounding the nozzle may be provided. Alternatively the nozzle may be additionally cooled by a flowing liquid or gaseous cooling medium for instance air or exhaust gases. The air nozzle may be of steel containing chromium or it may be of ordinary steel or cast iron with a delivery end of high grade steel formed thereon by electrical deposition welding. Also a thinner layer of the high grade steel may be formed around the nozzle adjacent the delivery end. It is stated that the pipe h has a silencing effect and a very simple type of exhaust gas silencer f may be provided. A proportion of exhaust gases to air of 1 :2 has been found to be most suitable. The crosssectional area of the nozzle i is preferably equal to that of the smallest part of the bore bo of the nozzle b. Burning away of the nozzle in the latter case is only one fifth of that when the exhaust nozzle cross-section is one and a half times that of the smallest part of the bore bo. It is stated that burning away of the nozzle is considerably reduced and where the delivery end is welded on it is not necessary to replace burnt nozzles completely it is necessary only to weld on new material in place of that burned away.
