  • Operation of Invention
  • The purpose of the subject invention “Solid Fuel Power Systems” is to generate economical heat and power for many different practical applications.
  • The subject invention power systems are based on the energy released from the enthalpies of formation of aluminum oxide, Al2O3, and water, H2O. These enthalpies of formation are −400.50 kcal/mol and −57.80 kcal/mol respectively. Both of these reactions are called exothermic because they give off energy. It is important to see the chemical equations to understand that hydrogen is generated in the Al2O3 reaction. This hydrogen then reacts with oxygen to form water and release a corresponding amount of energy also. The chemical equations are:
    2Al+3H2O→Al2O3+6H−400.5 kcal/mol
    6H+3O→3H2O−173.4 kcal/mol
  • The total amount of energy released from these two reactions is 573.9 kcal resulting from the oxidation of about 54 grams, or 0.12 pounds of aluminum. Calculations show that the energy from the above reactions is about 44.5 MJ/kg for aluminum, and this is about the same as the energy content of gasoline.
  • Aluminum is very attractive as a fuel for the production of heat and power. This patent application is for the practical applications of aluminum as a fuel. Aluminum was created by nova nuclear reactions, and did not go through an organic phase as did the creation of fossil fuels, which include oil deposits. Aluminum is the most abundant metallic element on earth, and constitutes 8.1% of the earth's crust. Aluminum deposits are widely distributed on earth and, therefor, are not likely to lead to the political stress for which concentrated oil field deposits have been responsible. There is no doubt that the oil deposits will be depleted in the near future. The large and widely distributed deposits of aluminum can supply our fuel requirements until the safe Neu2 nuclear fuels are available.
  • Aluminum fuel for the production of heat and power is a clean fuel. Unlike our fossil fuels such as oil and coal, aluminum fuel is environmental friendly. Aluminum fuel does not threaten the ozone layer. Aluminum has a low melting point of 660° centigrade or 1221° Fahrenheit, and that makes it ideal for the fuel power systems in this patent application.
  • In this patent application for “Solid Fuel Power Systems” it is possible that molten aluminum, or powdered aluminum, can be used interchangeably for the applications cited, where the operating temperature in the application is above the melting temperature of aluminum. To produce heat and power, the chemical reaction with aluminum to form Al2O3 is dependent on complete oxidation of all the aluminum fuel in the particular application. A very clean metallic surface of aluminum is required. For this purpose molten aluminum spray is used. The same effect is achieved with a spray of aluminum powder into a chamber where the temperature is above the melting point of aluminum. Oxygen for formation of Al2O3 can be obtained from air, water, alcohol, any suitable oxidizing substance, or a mixture of these.
  • FIG. 1 illustrates an aluminum fuel application for a power a piston reciprocating engine. Molten aluminum spray, or aluminum powder spray, is mixed with water spray to generate heat. The resulting steam pressure forces the piston to move in the cylinder to perform work. The engine is a two-cycle reciprocating engine. Exhaust valves are located in the head of the cylinder.
  • FIG. 2 shows an example of multiple molten aluminum sprays, or powdered aluminum sprays, with water sprays to generate heat in an energy chamber. The heat can be removed by cooling coils, or steam pressure can be allowed to build up for use in a steam turbine.
  • FIG. 3 illustrates a water boiler application using molten or powdered aluminum fuel sprayed on to the surface of water in a reservoir. Heat can be removed by cooling coils, or high temperature and high-pressure steam can be generated for use in a steam turbine. FIGS. 4, 5, and 6 constitute a family of figures to illustrate the use of fuel spray rings to generate heat and power for any application, but most specifically for operating a gas turbine with aluminum fuel.
  • All of the above application concepts come together in FIG. 6 where a turbojet engine configuration is shown. The air compressor is powered by a turbine that in turn is powered by heat and pressure generated in the combustion chamber. The heat comes from the oxidation of powdered aluminum, and also by conventional jet fuel.
  • In the gas turbine, oxygen for oxidizing molten aluminum spray is obtained from the compressed air flow. Also, in the very high temperature environment of the combustion chamber, aluminum powder fuel can be melted and oxidized to generate heat. FIG. 5 shows a jet fuel nozzle ring arrangement where ordinary jet fuel, or kerosene, is sprayed into a high temperature and high-pressure air flow combustion chamber along with molten or powdered aluminum fuel to generate heat. The ordinary jet fuel spray can be discontinued when the combustion chamber temperature is above the melting point of aluminum. At that time, all of the heat and power produced in the combustion chamber comes from the aluminum fuel and the hydrogen produced in the chemical reaction.
