  • Patent number: 9777673
    Abstract: A method is provided for solid-propellant engines to be dismantled safely and in accordance with environmental standards having been scrapped. For each engine to be dismantled, it is mounted on a static test rig, immersed in a tank filled with water and started such that propellant is used up under the water. The soluble part of the combustion products (gases or condensates) thus remains trapped in the water in the tank while the non-soluble solid products drop to the bottom of the tank. The body of the engine emptied of its fuel in this way and rendered pyrotechnically inert is then taken apart or disassembled. Periodically, the water in the tank is withdrawn and the tank stripped of its deposits such that subsequent dismantling operations can be carried out under proper conditions. All of the combustion products recovered are sent to appropriate reprocessing plants. The method allows high dismantling rates.

    Abstract: A process of oxidizing an ash and sulfur containing fuel such as coal in order to power gas turbines using a material such as the oxides of iron which in an oxidized state can be readily reduced and which in a reduced state is readily oxidized. Preferably, the oxides of iron are circulated between two fluid bed reactors and reduced by the ash and sulfur containing fuel in the first said fluid bed reactor and oxidized by air in the second said fluid bed reactor, with ash and SO2 in the gases leaving chiefly from the first said fluid bed reactor. The temperature is controlled within the second said fluid bed reactor by use of a clean fuel and the rate of addition of the ash and sulfur containing fuel to the second fluid bed is controlled so as to limit the amount of SO2 in the gases leaving the second said fluid bed.

  • Patent number: 6101957
    Abstract: An apparatus for the disposal of solid rocket motors which produce exhaust ases containing flammable and/or explosive products. The solid rocket motor to be burned is first detachably connected to and inserted in one end of an elongated mixing chamber which has, at an opposite end, a multi-step expansion nozzle. The rocket motor is then ignited and the exhaust gas is passed into the mixing chamber, which is sufficiently large to reduce the velocity of exhaust gases from supersonic to subsonic. Air is injected into the mixing chamber to react with flammable and/or explosive products in the exhaust gases and the resultant mixture is then discharged from the mixing chamber through a multi-step expansion nozzle to expand the gaseous mixture and, at the same time, produce substantial turbulence within the gas mixture which is about six times higher than the turbulence levels produced by a constant area circular nozzle.
