Abstract: Methods for forming glass compositions from cullet include providing the cullet to a submerged combustion melter and melting the cullet with the aid of heat generated upon the combustion of a hydrocarbon from landfill gas and, in some cases, a polymeric material, in the presence of an oxidant. The melted cullet is then directed to a fiberization unit to generate a glass composition, such as vitreous fiber. The glass composition can be used to form various structural components, such as glass fiber insulation. Methods and systems provided herein can be used to form low global warming potential products.

Abstract: A modular mobile furnace train apparatus and a process is disclosed. Mobile furnaces may be interconnected in series to form a modular mobile furnace train. Exhaust gas may then flow through mobile furnaces in a furnace train, allowing for more effective heat transfer to payload being heated as well as increasing energy recapture. Volatile gasses emitted by the payload may be combusted. This recapture reduces production of carbon dioxide and reduces the amount of energy required during the firing while the combustion of volatiles reduces exhaust pollutants. A fire line is an area where heat is applied, while a service line is an area where loading, unloading, inspection, and ongoing maintenance may take place. The modular mobile furnace train allows separation of the fire and maintenance which reduces worker exposure to dangerous environments while decreasing operational costs. Furthermore, the modular mobile furnace facility is less costly to build and operate.

Abstract: The invention relates to a method and apparatus for processing oil drilling waste. According to the invention, oil drilling waste of one or more types is selected, and is introduced from the feeding tanks into a rotating kiln; and in the kiln, the oil drilling waste is processed at a temperature of 110 to 13500° C. to form granules having a compact-coated surface.

Abstract: A method and apparatus for heating a liquid storage tank includes a liquid storage tank having an interior and a peripheral sidewall. An engine compartment is appended to the peripheral sidewall in front of the heat tube. An engine is disposed in the engine compartment. Heat given off from the engine during operation heats the engine compartment and such heat is transferred through peripheral sidewall to the interior of the liquid storage tank. An exhaust conduit extends into the interior of the liquid storage tank. Heat from hot exhaust gases passing through the exhaust conduit heats the interior of the liquid storage tank.

Abstract: An apparatus for warming objects such as production conduits at a well site comprises an internal combustion engine driving a well pump. A heat exchanger shell is connected to an exhaust port of the engine, and has an output port. A circulating pump is driven by the engine, and a heating circuit is connected to the circulating pump such that liquid in the heating circuit is pumped from a pump output of the circulating pump through the heating circuit to a pump intake of the circulating pump. The heating circuit comprises a heat absorbing portion inside the heat exchanger shell arranged such that heat from the exhaust of the engine is transferred to the liquid therein, and a heating conduit arranged adjacent to a production conduit or other desired object such that heat from the liquid in the heating conduit is transferred to the object.

Abstract: An axially rotatable materials handling apparatus for handling a mixture of solid particulate and water, includes a heater mounted on the housing that can transfer heat to the mixture to prevent or thaw frozen water inside the apparatus. The heater can be a combustible fuel heater or an electric heater. The apparatus is particularly useful in winter weather to prevent water from freezing inside the apparatus or to thaw any frozen water already present.

Abstract: A portable, easily-transported and erected horizontal surge/storage silo functions by the method of allowing large, long distance trucks to dump their contents of materials to be used at a nearby point of use onto the base of the portable silo from which the materials may be subsequently restacked and reloaded by suitable materials-handling devices, such as front-end loaders, onto other smaller vehicles for subsequent transport to the point of use or disposal. A base is sufficiently strong and configured to support upstanding sides and a roof if a roof is desired to provide a totally closed or sealable unit. Where provided, the roof may be removable and the sides may have a fast-closing entrance and door for easy access and safe and protected storage. The structure may have a retractable set of wheel devices affixed thereto so that it may be moved into and out of ground engaging position to make the unit respectively portable and operational.

Abstract: An elongated slot dryer is disclosed for drying wet solid particulate material. The slot dryer is constructed in the form of a trench with at least one aperture outlet at the bottom of the trench formed by two non-connecting walls. The wet particulate material (coal) enters through the top and exits through the bottom aperture while countercurrently contacting a drying fluid emitted through perforations situated in a drying fluid access means or conduit located substantially throughout the entire length of the slot dryer. The perforations in the fluid access means or conduit are limited to the bottom one half of the fluid access means relative to the aperture outlet to ensure that drying fluid is passed at first in a downward direction and then gently turns upward to countercurrent contact with the wet descending particles. An underlying conveyor will act to continuously remove the relatively dried particulate material passing through the aperture outlet.

Abstract: A method of treating, in a vertical grate furnace, raw materials in an iron reduction process is disclosed. The raw materials are fed onto a grate-containing section which is separated from at least one other section of the grate furnace. Subsequently, the grate-containing section is attached to the other section or sections by moving the other section or sections upwardly or downwardly so as to achieve and maintain gastight conditions between the grate-containing section and the other section(s). The raw materials then undergo preliminary heat treatment in the grate furnace. Finally, the grate is tilted to discharge the treated materials from the grate furnace through an outlet provided on the side wall of the furnace.

Abstract: A heat-treating apparatus for practicing a method in which when red-hot iron pipes produced by a centrifugal casting machine are cooled, the pipes are slowly cooled over the temperature range of 800.degree. to 700.degree.

Abstract: A forced air heater using self-pressurizing fuels such as propane or butane to drive the blower incorporates an overheat dump port to provide an auxiliary exit for the hot air in the event that the normal outlet becomes obstructed. Also included are means for removing condensation from the fuel conduit, for preheating the fuel source, and for continuing to warm the fuel source and fuel conduit to improve operation of the forced air heater in cold environments. The overheat dump port also provides access into the heater for the high voltage conduit of a spark generator for igniting the fuel within the need for insulating the high voltage conduit.
