    摘要: Material remediation apparatus includes a remediation drum through which materials, such as soil contaminated with hydrocarbons, are advanced from a feed end to a discharge end of the drum. A tube extending concentrically from the discharge end of the drum into the drum forms a combustion chamber. Materials being decontaminated advance through an annular space between the tube and the drum. The tube is axially first of converging and then of diverging shape, as viewed from the discharge end of the drum. A turbo burner injects combustible gases into the tube which are burned within the diverging shape of the tube. A portion of the burned gases reflow from the outlet of tube through the annular space to the discharge end of the drum. In a zone of the drum occupied by the tube materials are heated by conduction and radiation of energy passing through the wall of the tube as well as by convective heating from the reflow gases. Hot gases are exhausted from the drum at the feed end thereof. However, hydrocarbons volatilized by the heating process in the annular space first pass with the reflow gases through the combustion chamber and are burned before being exhausted. The exhaust gases are filtered in a baghouse filter. Materials from which hydrocarbons have been extracted by volatilization in the annular space are cooled and reconstituted by water injection. Steam generated as a result of the water injection is filtered in a separate filter section of the baghouse filter.

    摘要: A burner assembly has a combustion chamber in which combustion takes place in an elongate centrally disposed combustion tube. An outer housing encases the combustion tube and provides an annular space between an inner wall of the housing and the combustion tube. Part of the exhaust gases exiting from the combustion tube are diverted from the downstream end thereof to be returned through the annular space to the upstream end of the combustion tube. Fuel is injected into the diverted exhaust gases, volatilized when in liquid form and mixed with the diverted gases. The fuel and gas mixture is further combined with a buffer gas and becomes entrained into and mixed with a high velocity of combustion air which is injected into the upstream end of the combustion tube. The flame temperature may be monitored and the quantity of the buffer gas added may be controllably varied based on temperature readings from the monitoring process to minimize the generation of nitrous oxides.

    摘要: An asphalt plant including a plurality of asphalt processing components, with a selected first set of the components producing volatile emissions and a selected second set requiring process heat energy. A central burner assembly is connected to the selected second set of components by an insulated duct system for providing heat energy to the second component set. A first duct system is adapted to capture a portion of the volatile emissions produced by the first component set and convey the captured emissions into the central burner for mitigation. The central burner is preferably a media burner incorporating flameless combustion technology as well as an adjustable internal fuel injection system, which results in safer and more controllable combustion. Even with captured fugitive emissions in the inlet air, the fuel injection system keeps the concentration of combustible materials well below the lower flammability limit.

    摘要: An improved extended auger arrangement and an improved asphalt paver with a tractor unit and a screed assembly, including a main screed and extendable screeds, having such an improved extended auger arrangement, the extendable screeds extending laterally outwardly from the main screed such that the screed assembly spans a width substantially greater than the width of the tractor unit. The extended auger arrangement includes a pair of opposing, oppositely pitched, inner augers, rotatable about a substantially horizontal axis oriented perpendicularly to the direction of travel of the tractor unit and approximately spanning the width of the tractor unit, and a pair of oppositely pitched outer augers, rotatable about respective horizontal axes oriented substantially non-perpendicularly to the direction of travel of the tractor unit and approximately spanning the difference between the width of the tractor unit and the width of the screed assembly. Each of the outer augers is drivingly and pivotally connected by a universal joint to a respective one of the inner augers. A supporting structure provides fore-and-aft support for the outer augers.

    摘要: A system for concurrently remediating contaminated soil and producing hot mix asphalt includes a single inclined rotary drum; a burner assembly with a burner head spaced intermediately within the drum and oriented to direct a flame and hot gas stream upstream therefrom; a secondary air tube for providing atmospheric air to the burner head for supporting combustion; a drying zone with veiling flights upstream from the burner head for receiving, drying and heating virgin aggregate; a combustion zone with combustion flights downstream from the drying zone and upstream from the burner head for receiving and remediating contaminated soil by heat transfer from the virgin aggregate, the flame and the hot gas stream and for oxidizing volatile contaminants vaporized from the contaminated soil; an isolated mixing zone for receiving various materials including the virgin aggregate, the remediated soil, recycle asphalt, and certain constituents for producing hot mix asphalt therein from thermal energy contained within those materials. A method for concurrently remediating soil and producing hot mix asphalt in a single rotary drum consistent with the foregoing is provided.
