A system, apparatus and method for the combustion of metals and other fuels are provided. The system can include: a fuel combustion apparatus including a combustor having a combustion chamber for burning ground particles from a fuel charge, and a fuel supply apparatus for supplying the ground particles of fuel from the fuel charge to the combustor. The fuel supply system can include a fuel charge holder assembly to house and store the fuel charge, a grinder assembly including a grinder housed within the charge holder assembly and configured to pulverize the fuel charge to produce a combustible fuel to be consumed in the combustion chamber, and a fuel charge linear feed assembly including a piston in contact with the fuel charge within the charge holder assembly to selectively bias the fuel charge into the grinder to thereby a control consumption rate of the fuel charge. Exhaust from the combustion chamber can be used in the incineration of radioactive, chemical and mixed hazardous materials, and in the propulsion of a vehicle in both an air or water environment.
