Steam powered vehicle such as locomotive with heat recovery, in which exhaust steam heat content is used via heat exchange plant for re-evaporation or evaporation

The steam powered vehicle or other steam plant has a heat recovery system in which the exhaust steam heat content is used via a heat exchange plant for re-evaporation or evaporation. It can be used for pre-heating the water supplied to form the steam or for the intermediate superheating of steam in a machine connector with two or more steam expansion stages.

Steam power source

A self propelled vehicle 100 for the carriage of passengers or goods is driven by a high pressure steam powered reciprocating engine 103. The engine burns bio ethanol fuel which may be supplied via a fuel tank 101 and a reactor chamber 102. The engine may drive a fly wheel 104, transfer box 106, and road wheels 105 via a conventional differential unit. Expended steam used in the engine may be returned though a condenser to the steam generator to complete a Rankine cycle.

Lighter-than-air craft using steam to provide buoyancy

An envelope of an airship or balloon is filled with steam to render it buoyant in air. As steam condenses the resulting water collects at a low point in the envelope and is either drained to atmosphere (fig. 3) or to a boiler B for re-boiling and return to the envelope (figs. 6, 7A, 8,9, 10,11). The water may be drained via a float valve 3 (fig. 4) which prevents steam from escaping from the envelope. In the case of an airship, a steam engine SE (reciprocating engine or turbine) may be provided for driving a propeller P, the exhaust from the engine being supplied via a hose 7, to the envelope, and the boiler B providing variable quantities of steam to the engine and direct to the envelope. A water reservoir WR, fuel tank FT, and ballonets BA, BF, may be provided. The envelope may be covered with insulating slabs (S fig. 7A) and may be fabricated from material comprising woven elastic fibres (fig. 12C).

This steam circuit includes a steam generator, a steam injector for injecting steam into the piston engine, a condenser for condensing the steam emerging from the piston engine to condensed water, and a water feeding pump for feeding the condensed water to the steam generator.

Apparatus for regulating the working of steam power plants

233,663. Schmidt'sche Heissdampf- Ges. May 7, 1924, [Convention date]. Addition to 231,451. Controlling-Apparatus, arrangements of hand or trasmission gear in conjunction with; controlling different functions by same lever; automatic power control.-Relates to locomotives as described in the parent Specification, comprising two or more steam generators working at different pressures and supplying steam to different stages of an engine, the regulators or stop valves of the separate generators being controlled by a single operating means which may be actuated by hand or automatically. According to the present invention additional hand or automatic control is superposed at certain times, as at starting or stopping, on the automatic control, so as to alter the steam distribution at those times. In the construction shown, two regulators (not shown) are operated by cams 15, 16 carried by a sliding sleeve 38 splined on a hand-controlled shaft 13, so that when this shaft is rotated the regulators are opened or closed, their relative openings depending on the position of the sleeve 38. This sleeve is moved axially by a piston 41 acted upon by a spring 43 and also at 44<1> by steam from the low-pressure generator. So far, the apparatus is as described in the parent Specification. The additional control comprises a larger piston space 42 acted upon by the exhaust steam. As at starting the exhaust steam pressure is higher than the normal, due to the later cut-off, the steam pressure on the piston 41 is greater at starting and thus the sleeve 38 is moved to the left, causing a greater proportion of steam to be taken from the low-pressure generator. A hand-controlled valve may be provided in the exhaust steam supply pipe. In a modification the piston 41 is simply acted upon by the low-pressure steam and the spring 43, the pressure of the latter being adjusted, when desired, by the driver.

Rankine engine with efficient heat exchange system

The Rankine engine with efficient heat exchange system (10) provides a rapidly rechargeable thermal energy storage bank operably connected to a heat engine capable of propelling a vehicle (V). Microwave energy is supplied to the system via a network of waveguides (200). A thermal storage bank has slurry (S) in a heat exchanger (60) capable of sustaining operation of the engine without requiring the microwave source (55). The slurry (S) provides a mixture of powdered stainless steel and silicone oils functioning as the working fluid in the hot side of the heat exchanger (60). The slurry (S) may be heated by plugging the system into standard AC power for a predetermined microwave heat charging duration. A closed, triple-expansion, reciprocating Rankine cycle engine capable of operating under computer control via a high pressure micro-atomized steam working medium is provided to propel the vehicle (V).
