The apparatus includes a grinder for grinding a mixture of the waste and calcium carbonate. The ground mixture is then fed to a molten metal bath contained within a crucible. Thereafter, a heating member configured proximal to the crucible combusts the mixture of the waste and the calcium carbonate to form one or more of slag and one or more acidic gases. On combustion, the one or more acidic gases are neutralized by calcium hydroxide produced as a result of combusting the calcium carbonate. Additional metal compounds usable as fertilizers are also produced in response to reacting with the one or more acidic gases.

    Abstract: A gasifier for disposing of biomass and other waste materials through a gasification and combustion process. The gasifier includes a primary chamber for receiving and holding biomass or a selected waste product. A heat transfer chamber is disposed adjacent the primary chamber. A burner is associated with the gasifier for generating heat and heating the gasifier during various phases or portions of the gasification and combustion process. In the gasification process, the heat transfer chamber is heated and the heat is transferred to the primary chamber where the biomass is heated. During the gasification process, biomass material is volatized generating fumes and gases that later react and release heat through exothermic reactions. Once the gasification process has been concluded, the process enters a combustion phase where the biomass is actually burned. During the gasification-combustion phases, the amount of heat supplied by the burner will vary.

  • Publication number: 20120312026
    Abstract: Pyrolyzing gasification system and method of use including primary combustion of non-uniform solid fuels such as biomass and solid wastes within a refractory lined gasifier, secondary combustion of primary combustion gas within a staged, cyclonic, refractory lined oxidizer, and heat energy recovery from the oxidized flue gas within an indirect air-to-air all-ceramic heat exchanger or external combustion engine. Primary combustion occurs at low substoichoimetric air percentages of 10-30 percent and at temperatures below 1000 degrees F. Secondary combustion is staged and controlled for low NOx formation and prevention of formation of CO, hydrocarbons, and VOCs. The gasifier includes a furnace bed segmented into individual cells, each cell is independently monitored using a ramp temperature probe, and provided with controlled air injection. Gasifier air injection includes tuyere arrays, lances, or both.

    Abstract: Waste is treated by pyrolysis at a temperature of from 400-700° C. and combustion at a temperature of at least 400° C. Off-gases are catalytically oxidized to reduce emissions. The combusting waste is periodically agitated with high-pressure air bursts to disrupt waste in the chamber and promote even and complete combustion. Air is introduced during pyrolysis to promote controlled flow of off-gas to the catalyst and air and/or water is used to dislodge accumulated ash at the end of the treatment process.

  • Patent number: 8263037
    Abstract: A method for producing carbon nanostructures according to the invention includes injecting acetylene gas into a reactant liquid. The injected acetylene molecules are then maintained in contact with the reactant liquid for a period of time sufficient to break the carbon-hydrogen bonds in at least some of the acetylene molecules, and place the liberated carbon ions in an excited state. The liberated carbon ions in the excited state then traverse a surface of the reactant liquid and enter a collection area where carbon ions combine to produce carbon nanostructures.

  • Patent number: 8240258
    Abstract: The present invention provides a burner which uses solid fuels, especially waste plastic fuels. Burner size is minimized by having multiple combustion chambers concentrically located around a rotating screw conveyor. Heat efficiency is improved by having air passages disposed around the combustion chambers, thus preheating air for the combustion prior to its delivery to the combustion chambers, while simultaneously thermally insulating the combustion chambers against the environment. Waste plastic is transported from a fuel hopper to the combustion chambers by a rotating screw conveyor having the spiraling auger blades. Speed of screw conveyor rotation controls the consumption of waste plastic and, thus, the amount of thermal energy generated in the burner.

  • Patent number: 8216345
    Abstract: A gasification system is disclosed having a combustion or reaction vessel, a scrubber housing, and a filter housing. A carbonaceous fuel is partially combusted in the reaction vessel to generate a combustible gas. An improved ash support and removal system reduces clogging and other problems in the reaction vessel. The combustible gas passes through the scrubber housing to remove matter such as tar and oil, and the scrubbed gas passes through a hybrid blower to the filter housing. Wood chips are used in the filter housing to provide a relatively clean, dry gas. Wastewater and other waste products from the scrubber housing and filter housing are captured and returned to the reaction vessel.
