摘要： A facility for conditioning compressed natural gas to be dispensed to vehicle fuel tanks is provided that includes a fuel storage system, a chilling apparatus, and a fuel dispensing system. The chilling apparatus includes a refrigeration system and a liquid separator. The refrigeration system cools the compressed natural gas to near freezing temperature and/or a sub freezing temperature to remove water vapor, to remove higher hydrocarbons, and/or to obtain a full fill of the vehicle fuel tanks. The liquid separator is located downstream of the refrigeration system to remove any condensed liquids from the natural gas. A desiccant bed can be provided downstream of the liquid separator to remove any residual liquids remaining in the natural gas.

摘要： A self-powered forced or induced draft water heater is provided including a tank adapted for storing hot water, a sealed combustion chamber, a powered burner, a thermoelectric module, and a through-chamber heat sink having a base portion and a pin portion. The combustion chamber has a common wall with the tank at a lower zone of the tank. The powered natural gas burner has a blower which delivers air to the burner through an inlet duct and forces combustion products out a flue. The thermoelectric module generates operating power for the burner blower. The thermoelectric module has a hot side in thermal communication with a combustion zone of the burner and a cold side attached to the heat sink base portion. The pin portion of the heat sink is conically shaped and extends through an opening in the common wall to the interior of the tank. The base portion of the heat sink is removably attached to the common wall and is provided with an o-ring or other means to seal the wall opening.

摘要： An apparatus and method for reducing nitrogen oxide emissions from the products of combustion is provided in which a vortex generator introduces natural gas, or other fluid fuel into the upper portion of a combustion device. The fuel introduced forms vortices, such as vortex rings, and the fuel reacts with the nitrogen oxide in the combustion products to form ammonia-like compounds, hydrogen cyanide and similar compounds, and nitrogen. The ammonia and cyanide-like fragments react with additional amounts of nitrogen oxide in the combustion products to form nitrogen gas, water vapor and carbon dioxide. The vortex rings can be controlled and will maintain their integrity longer than puffs or simple jets of fuel.

摘要： A method of recycling fly ash as slag in a wet bottom furnace is described. The furnace may have a cyclone furnace, a pulverized coal furnace, or any other type of furnace producing wet slag. All or part of the collected fly ash is collected and returned to the furnace and combined with enough fuel to melt the ash. Melted ash directed against a wall, floor or side of the cyclone or furnace will flow to the bottom of the furnace so as to facilitate the liquid slag. The fly ash may be collected by an electrostatic precipitator, baghouse, cyclone (multiclone) or other device. The fly ash may be returned to the furnace or the cyclone using air, flue gas, steam, fuel, or other gas as a carrier.

摘要： A cogeneration plant for a site having an expected daily thermal load. In one embodiment, the plant includes a heat engine/electrical power generator set and a heat storage unit. The engine/generator set is sized to normally operate only during the peak rate period of the central electric service utility while rejecting a quantity of heat equal to the daily thermal load at the site. The storage unit is sized to contain a quantity of heat equal to the daily thermal load reduced by that portion of the daily load incurred during the peak rate period. In another embodiment, the cogeneration plant includes a fuel cell electrical power generator serving a local energy-integrated community. The fuel cell is sized to reject a quantity of heat to satisfy the collective average daily thermal load at the community site. Separate thermal storage sections are provided for high and low grade rejected heat.

摘要： An air heating and cooling system for a building includes an expansion-type refrigeration circuit and a heat engine. The refrigeration circuit includes two heat exchangers, one of which is communicated with a source of indoor air from the building and the other of which is communicated with a source of air from outside the building. The heat engine includes a heat rejection circuit having a source of rejected heat and a primary heat exchanger connected to the source of rejected heat. The heat rejection circuit also includes an evaporator in heat exchange relation with the primary heat exchanger, a heat engine indoor heat exchanger, and a heat engine outdoor heat exchanger. The indoor heat exchangers are disposed in series air flow relationship, with the heat engine indoor heat exchanger being disposed downstream from the refrigeration circuit indoor heat exchanger. The outdoor heat exchangers are also disposed in series air flow relationship, with the heat engine outdoor heat exchanger disposed downstream from the refrigeration circuit outdoor heat exchanger. A common fluid is used in both of the indoor heat exchangers and in both of the outdoor heat exchangers. In a first embodiment, the heat engine is a Rankine cycle engine. In a second embodiment, the heat engine is a non-Rankine cycle engine.

摘要： A process and apparatus for the production of intermediate hot metal suitable for further refining into steel is disclosed.The basic process includes the steps of heating a charge of ore in a reducing furnace having a reducing atmosphere therein comprising a mixture of reconditioned and recycled top gas from the reducing furnace and off-gas rich in hydrogen and carbon monoxide produced by a cupola melting unit to reduce the ore to iron, partially carburizing the reduced iron in the reducing furnace with carbon-containing off-gas produced by the cupola melting unit, and melting the reduced and carburized iron together with scrap, slag forming additives and fluxes in a cupola melting unit having a reducing atmosphere therein produced by the combustion of a rich fuel/oxidant mixture to form a molten slag and molten iron suitable for the further refining to produce steel. The process contemplates the further refining of the molten iron from the cupola in an electric steelmaking furnace or an oxygen steelmaking converter. In an alternative form of the process, the reduced and carburized iron is cooled within or outside the reducing furnace to form prereduced metal pellets suitable for use as a part of the burden in a melting unit.The apparatus comprises a refractory lined cupola melting unit portion equipped with burners capable of burning a rich fuel/oxidant mixture to produce a reducing atmosphere within the melting unit and off-gas rich in gaseuos reductants, a direct reducing unit portion communicating with the upper end of the melting unit to receive the melting unit off-gas recirculating and conditioning means to recycle at least a portion of the top gas from the upper region of the reducing unit portion to the lower region of the reducing unit portion, means for introducing ore into the direct reduction unit portion of the apparatus, and means for introducing additives and fluxes into the melting unit portion of the apparatus.
