  • Patent number: 8789480
    Abstract: An energy and steel recovery system has a suspension column and a plurality of suspension supports operably disposed therein wherein the supports are spaced from one another along the length of thereof. The suspension column includes a mechanism for receiving tires and other wastes with an energy value onto one of the supports and feeding the tires to an adjacent downwardly disposed support to further gasify the same under low oxygen to preclude combustion. The column is configured to provide for a number of zones including heating, drying, volatizing, and fixed carbon formation which are collectively referred to herein as a “fractionation process.
    Type: Grant
    Filed: August 25, 2010
    Date of Patent: July 29, 2014

  • Patent number: 7647874
    Abstract: An energy and steel recovery system has a suspension column and a plurality of suspension burners operably disposed therein wherein the burners are laterally spaced from one another along the length of thereof. The suspension column includes a mechanism for receiving tires onto one of the burners and feeding the tired to an adjacent downwardly disposed burner to further combust the same. A first conduit includes a first end communicably connected to the suspension column and a second end communicably connected to a boiler wherein air flow passes from the boiler to the suspension column. A second conduit includes a first end communicably connected to the suspension column and a second end communicably connected to the boiler wherein air flow passes from the suspension column to the return air flow path of the boiler. The system includes a mechanism for removing residual waste materials from the suspension column.

  • Patent number: 4157281
    Abstract: A solvent-bearing sludge material is pumped by a variable speed positive displacement pump from a preparation mixing tank through a pressure responsive valve which distributes the material into the upper portion of an insulated distilling or processing vessel. Steam is introduced into the lower portion of the vessel and mixes with the material to volatize the solvents which are directed through a condenser and pump to a storage tank. Water and suspended solid particles are continuously pumped from the bottom of the vessel to an insulated settling tank where the solid particles settle and are continuously removed by a drag-out conveyor. The hot water in the upper portion of the settling tank is pumped back into the vessel, and may have sufficient velocity to increase agitation within the vessel, or a mechanical agitator may be installed within the bottom portion of the vessel.
