摘要： Fugitive methane or natural gas vapors are recovered from a handling or delivery system and are blown through solid methane chips or a slush of solid and liquid methane. The solid methane melts and cools the vapors below the vaporization temperature to condense them. The condensed vapors and melted solid can be mixed with liquid methane for use therewith. The solid methane is produced by cooling liquid methane or natural gas in a liquid nitrogen heat exchanger or refrigerator. The liquid methane is solidified in a sheet on an endless belt, which breaks the sheet into pieces at a tail section.

摘要： In a process to limit the production of flyash by dry bottom boilers, flyash is collected from flue gas using a collector such as an electrostatic precipitator. The collected flyash is carried in a carrier gas stream to which a fuel is added. The stream is introduced into the boiler in a manner to cause the flyash to soften, agglomerate and fall into the bottom ash pit.

摘要： A method and apparatus for reducing emissions from an internal combustion engine used for propelling a heavy land vehicle, for example, comprising a fuel supply tank for storing liquified natural gas and a fuel circuit for cooling compressed charge air to the engine with the heat of vaporization of the fuel. Under low load conditions fuel vapor from the tank can be consumed to avoid an excessive build-up of pressure; the engine is operated with a lean fuel/air mixture without cooling of the charge air to obtain low emissions. Non-methane hydrocarbon emissions are eliminated by stripping the natural gas of essentially all of the higher hydrocarbons during the liquification process.

摘要： A method is disclosed which overcomes the problems which tend to occur in application low-NOx burners to coals in which the volatile matter is low in heat content. A gaseous or volatile liquid fuel is introduced into the ignition zone and/or the primary flame immediately downstream of the burner. This fuel will have the same effect as increased quality and quantity of the volatile content of the coal.

摘要： A system for air conditioning and generating electrical power including a fuel-fired internal combustion engine, an electrical motor/generator, and a vapor compressor/expander all interconnected. The vapor compressor/expander driven by the engine operates in one mode with an evaporator and a condenser in a generally conventional refrigeration cycle. In an alternative mode, the vapor compressor/expander is operated in reverse by refrigerant boiled in the evaporator by the rejected heat of the engine and condensed in the condenser and contributes mechanical power to that of the engine to drive the motor/generator. The motor/generator can be supplied external electrical energy to operate as a motor to drive the compressor/expander during periods of non-operation of the engine.

摘要： Gas-solids transport and heat exchange techniques are disclosed wherein solid particulate material is circulated in a "figure 8" or a circular flow path for selective contact and/or direct heat exchange with gaseous media. The particulate material is introduced into streams of gaseous media at spaced locations in the flow path and subsequently separated from the gaseous streams following contact and/or heat exchange therewith. The gaseous streams are maintained separate from one another by loose packed bed columns of particulate material formed in the flow path and used to introduce the particulate material into the gaseous streams. The flow rate of the particulate material is regulated by the controlled biasing of particulate material from each of the columns thereof directly into the gaseous streams, and the particulate material is circulated solely through the use of the gaseous media and the force of gravity. The particulate material is circulated in cocurrent relationship with each of the gaseous streams in figure 8 flow path systems and, in circular flow path systems, the particulate material is circulated in cocurrent relationship with one of the gaseous streams and in countercurrent relationship with the other of the gaseous streams. In heat exchange applications, heat transfer between the streams of gaseous media is provided as a function of the flow rate of the particulate material and the relative flow rates of the streams of gaseous media.

摘要： A process for stabilizing sludge containing flyash and calcium sulfate formed by a lime or limestone scrubber increases the sludge particles to a size at which leaching of toxic metals from the particles no longer occurs at toxic levels. The sludge is dewatered and injected into the furnace in a manner to cause the flyash to soften and stick together. The agglomerated particles then fall into a bottom ash pit for removal as a common waste.

摘要： An apparatus and method to improve pulverizer operation and reduce nitrogen oxide emissions from furnaces which burn pulverized coal from at least one pulverizer. A duct type burner burns a fuel in the primary air which heats the primary air supplied to the pulverizers. The combustion increases the primary air temperature and improves the drying of the coal, thus improving the pulverizer throughput and/or the fineness of the pulverized coal. Operation of the duct burner also reduces the oxygen in the primary air. The reduction in oxygen reduces the propensity of the coal to ignite in the pulverizers and cause fires or even explosions. The reduced oxygen in the primary air also reduces NO.sub.x formation.

摘要： A combustible fuel containing 3% to 45% of the fuel needed to operate a gas turbine is introduced into the compressor air stream for the gas turbine. The mixed fuel and air stream is introduced to the gas turbine prior to the combustor stage through a pipe, orifice or nozzle. The mixed air and fuel stream serves to reduce the nitrogen oxide emissions of the gas turbine. Waste air streams such as mine ventilation air may be used as the mixed fuel and air stream.

摘要： A heating system that reduces the cycling losses of a heat engine driven heat pump by storing rejected heat from the engine and using this rejected heat to meet a heating demand between periods of operation of the engine and heat pump so that over an extended time fewer start/stop cycles of the engine and heat pump are necessary. In a preferred embodiment a conventional storage-type hot water heater is used to store rejected heat, provide potable hot water, supply heat in the event of failure of the heat pump, supplement heat in periods of unusual demand, and provide low level heating requirements when heat pump operation would not be economical.
