Abstract: 300,631. Schmidt'sche Heissdampf- Ges. Nov. 17, 1927, [Convention date]. Compound and multiple expansion engines.- Relates to motor power plant comprising a twopressure compound steam engine, and an internal-combustion engine in which the heat of the cooling jackets of the I.C. cylinders serves to generate low-pressure steam. The steam generated in the jackets of the I.C. cylinders is used to generate steam by indirect contact, and this latter steam is superheated before admission to a low-pressure stage of the steam engine. Fig. 1 shows an arrangement in which a compound steam engine 2 - - 5 and a four-cylinder I.C. engine. 6 drive a propeller shaft 7. Steam generated in a boiler 1 is highly superheated at 22, and supplied to the high-pressure cylinder 2 and also .to interstage superheaters 21, 29. The cooling jackets 12, Fig. 2, of the I.C. cylinders are arranged so that steam generated in them is separated from water in headers 14, and passed by pipes 17 to heating coils 18 in a common steam generating drum 19. This cooling fluid works in a closed circuit, and distilled water, or liquid having a higher boiling point, may be used. Steam generated in the drum 19 is led by pipe 30 to the superheater 21 where it mixes with the exhaust from the high-pressure cylinder 2 before admission to the cylinder 3. The exhaust from the low-pressure cylinder 5 may, be passed to a turbine for driving the charging pumps for the I.C. engine. The exhaust gases of the I.C. engine pass by a pipe 8 to a feed-water heater 9 for the main boiler 1, and may then be used in an air preheater. The feed-water from the heater 9 may pass through the steam generating drum 19.
