In a thermochemical regenerator wherein gaseous combustion products that are formed by combustion in a furnace are passed from the furnace into and through a first regenerator, the combustion products are combined with gaseous fuel, and the resulting mixture is passed into and through a second regenerator wherein the mixture undergoes an endothermic reaction to form syngas, the thermochemical regeneration is enhanced by injecting fuel gas into a recycle stream comprising the combustion products from the first regenerator to entrain recycled flue gas that passes out of the first regenerator and to impel the mixture into the other regenerator.

This disclosure presents a clean burning flare stack, or gas flare, especially the tip portion thereof. The gas flare tip is air assisted to ensure clean burning. The disclosed gas flare tip provides smokeless clean burning of released gases. For example, the gas flare tip burns the released gases in a lean burning condition such that sufficient air is supplied to the surges of gases. In addition, the gas flare tip, by using a low pressure blower mixing chamber, is capable of handling low pressure gases and high pressure gases. As such, different flow rates may be provided to the gas flare tip when different amounts of low pressure and high pressure flammable gases are mixed with sufficient blower air to provide a clean burning condition. The disclosed smokeless gas flare is thus environmentally friendly and aesthetically appealing.

A method and system for controlling the nitrogen concentration in an LNG product and fuel from flash gas within preferred ranges. A cooled LNG stream is separated into a nitrogen-enriched vapor stream, a fuel stream, and an LNG product stream using a plurality of phase separating devices, such as flash drum or rectifying column. A portion of the vapor stream is recycled to the rectifying column as reflux. A portion of a stream having a higher concentration of nitrogen is combined with the fuel stream to maintain the fuel stream within a desired nitrogen concentration range.

A solar chemically recuperated gas turbine system includes an exhaust-gas reformer, a solar reformer and a gas turbine unit with a combustion chamber. The reaction outlet of the exhaust-gas reformer is connected to the inlet of the solar reformer, the flue gas side inlet of the exhaust-gas reformer is connected to the exhaust-gas outlet of the gas turbine. The solar reformer outlet is connected to the combustion chamber inlet. Combustion gas drives the gas turbine after fuel burns in the combustion chamber, and the exhaust gas enters the exhaust-gas reformer. Fuel and steam are mixed and enter the reaction side of the exhaust-gas reformer through a fuel inlet. A reforming reaction between the fuel and steam under heating of the exhaust gas generates syngas. A further reforming reaction occurs by absorbing concentrated solar energy after the syngas enters the solar reformer, and the reactant is provided to combustion chamber.

A printed circuit-type heat exchanger includes a vaporizer having a structure in which one or more A-channel plates and one or more B-channel plates are sequentially stacked, to vaporize a fluid A with heat exchange through the A-fluid channels. A gas-liquid separator separates the fluid A into a vaporized gas and a non-vaporized liquid and includes a gas outlet for the vaporized gas and a liquid outlet for non-vaporized liquid. A super heater, having the same structure as the vaporizer, super heats the vaporized gas with heat exchange through the A-fluid channels and discharges the superheated gas through a gas outlet communicating with the outside. A first intermediate plate is disposed between the vaporizer and the gas-liquid separator to separate the vaporizer from the gas-liquid separator, and a second intermediate plate is disposed between the gas-liquid separator and the super heater to separate the super heater from the gas-liquid separator.

The invention relates to a method for the thermal disposal of pollutants in industrial gases, wherein, in order to generate a flame for burning the pollutants, a fuel gas and oxygen are fed into a combustion chamber (19) of a burner (1), where they are then ignited, wherein a diluent gas is fed in in order to reduce the calorific value of the gas mixture relative to the fuel gas, while the throughput of the diluent gas is regulated as a function of the composition of the industrial gas in order to adapt the gas mixture consisting of diluent gas and fuel gas. The invention also relates to a burner (1) for generating a flame (2) in a combustion chamber (19) for burning pollutants in an industrial gas, and to a waste-gas treatment device having at least one burner (1) arranged in a combustion chamber (19).

A hydrogen chloride loop fuel reaction is designed and configured for turbine/generator combination which can be used for automotive propulsion or as a standalone electrical generation or for auxiliary equipment. A method for providing a hydrogen chloride loop fuel reaction includes creating hydrogen chloride fuel in a sealed furnace vessel, wherein at start up, the sealed furnace vessel is vacuumed out and hydrogen and chlorine are injected into a burner and ignited resulting in the hydrogen chloride fuel in an exhaust stream of the sealed furnace vessel; and looping the hydrogen chloride fuel leaving the sealed furnace vessel in the exhaust stream of the sealed furnace vessel.

The invention relates to a system for treating hydrogen and/or oxygen gas produced by water electrolysis and serving to supply a combustion process, characterised in that it comprises at least one heat exchanger, in which the one or more gases circulate so as to be cooled or heated, said heat exchanger being submerged in a reactive compound through which the one or more gasses pass in turn.
