摘要:
Antriebsaggregat mit aussentuftunabhängiger Verbrennung von Treibstoffkombinationen, insbesondere für den Unterwassereinsatz. Als Brennstoff ist ein Gemisch aus Kohlenwasserstoffen und Alkalimetallhydriden in pastösem und pumpfähigem Zustand, vorgesehen, während für den Oxidator ein Alkalimetallchlorat oder - perchlorat eingesetzt ist, das durch Zugabe von Wasser zu einer förderbaren, hochkonzentrierten, sauerstoffabgebenden Lösung gemischt ist.
摘要:
A method of operating an internal combustion engine in which there is introduced into a combustion chamber, inert carrier gas, combustion supporting gas and fuel, the fuel is caused to combust in the combustion chamber and exhaust gas is exhausted from the combustion chamber wherein the carrier gas comprises a significant proportion of carbon dioxide and the exhaust gas is treated with water to remove from the exhaust gas and absorb in the water an amount of carbon dioxide generally equal to the quantity of carbon dioxide added by said combustion, and the thus treated exhaust gas is returned to the combustion chamber to provide the carrier gas. The carrier gas may have inert gas such as argon added thereto in proportions controlled such that the gamma value of the mixture of gases equals a predetermined value which may be approximately that of air.
摘要:
57 A fuel composition for a reaction chamber which when combined with a selected reactant produces heat energy and hydrogen gas. A reaction chamber structure, method of making and method of operating the reaction chamber are also disclosed. A reaction system for a Rankine cycle steam engine in which water is reacted with a two-part fuel to produce heat and hydrogen. The starting part (38) of the fuel comprises lithium hydride, aluminium and magnesium and is the first to be contacted by the water. The heat of reaction liberated melts the main part (40) of the fuel, which comprises magnesium and aluminium which then also reacts with the water. The water is introduced through an inlet (14), the hydrogen leaves via an outlet (16) and the heat is removed by a heat exchanger (20).
摘要:
A power plant (10) comprising: a reaction chamber (12) for containing a reactive metallic fuel (14); a boiler tube (26) in association with the reaction chamber (12) having an inlet (28) and an outlet (30), and being arranged to be in heat receiving relationship with the metallic duel (14); a reactant source (16) for supplying an exothermically reactive reactant to the reaction chamber (12); a working fluid source for supplying a liquid working fluid to the inlet (28); and a conduit (42) for communicating pressurised vapour of the working fluid from the outlet (30) to a vapour pressure expanding motor (401; a first feed rate control valve (38) for selectively regulating the rate of supply of the working fluid to the inlet (28); attemperating means for communicating liquid working fluid from the source thereof to the conduit (42); and a second feed rate control valve (54) for selectively regulating the rate of communication of the liquid attemperating working fluid to the conduit (42).
摘要:
A closed Rankine cycle steam engine which is used to propel underwater vehicles without exhausting combustion products to the surrounding water. A solid metallic fuel (14) comprising lithium and aluminium reacts in the first chamber (12) with water to produce hydrogen which is subsequently reacted in a second chamber (16) with oxygen to produce superheated steam. Heat produced in the first chamber (12) is used to raise steam in a heat exchanger (30) which is used to quench partially the superheated steam before this is used to drive a turbine (20). The amount of water produced in the second chamber (16) is equal to the amount of water consumed in the first chamber (12) Consequently, no excess water is produced.
