Burner assemblies are configured to deliver decompressed mobile phase of supercritical fluid chromatography systems to the flame of a flame-based detector while providing for improved optimization of analyte response as well as enhanced flame stability during operation.

A method for heating reactor using a multi-function burner comprising feeding primary fuel through an annular channel, feeding oxygen through a central channel within the annular channel, and feeding an auxiliary fuel through a central lance within the central channel to produce a flame extending into a furnace having a temperature and a pressure; wherein the flow rate of the auxiliary fuel and oxygen are increased while maintaining an equivalence ratio below 1 to increase the temperature of the furnace; wherein after the furnace temperature exceeds the auto-ignition temperature of the primary fuel, increasing the flow rate of the primary fuel to increase the equivalence ratio to be greater than 1.

A Smart Candle Platform may be configured to produce candle light using a natural wax candle as its fuel source or any other fuel source capable of producing light, including liquid fuels if so configured. The outer shell, inner cover, top cover and base provides a beautiful exterior shell which does not melt but emulates the look of a traditional pillar candle. The outer shell may be changeable/replaceable allowing for style and or seasonal changes. A Smart Candle Platform having multiple interactive systems and sensors for production of natural light via a safe, controllable device which may communicate with other similar configured devices or smart devices having application software embedded therein i.e. a smart phone having an app. is disclosed. The Smart Candle Platform may be configured to allow for auto-extinguishment. The Smart Candle Platform may be configured to allow for the addition of smells or scents.

A method for turning an atomizing burner from an ON state to an OFF state is provided. The burner has independently controllable flows of atomizing air, combustion air, and fuel flow, the burner in the ON state having flow values of burner parameters including flow of atomizing air, flow of combustion air, and fuel flow. The method includes: changing, in response to an OFF instruction, flow of at least one of the flow of atomizing air, combustion air and/or fuel to a lower non-zero value; first discontinuing, after a first period of time since the changing, flow of fuel and flow of atomizing air; maintaining, for a second period of time since the first period of time, flow of combustion air; second discontinuing, after the maintaining, flow of combustion air; wherein the maintaining prevents buildup of excess heat inside the burner during the transition to the OFF state.

Variable momentum burner assembly for separately injecting fuel gas and oxidant in a combustion zone, comprising at least two fuel gas canals, at least one oxidant canal and a fuel gas distributor, whereby the at least two fuel gas canals comprise an inner fuel-conducting passage forming an inner fuel gas outlet and an outer fuel-conducting passage forming an outer fuel gas outlet, said inner and said outer fuel-conducting passages being coaxially arranged; and whereby said fuel gas distributor comprises a first fuel gas chamber in fluid connexion with the inner fuel-conducting passage of the at least two fuel gas canals and a second fuel gas chamber in fluid connexion with the outer fuel-conducting passage of the at least two fuel gas canals.

The present disclosure generally relates to fuel burners, for example, for use with photonic crystals as part of thermophotovoltaic power generators or with other thermal power generators. In certain aspects, fuel is supplied into a reaction tube and mixed between swirling streams of gases moving in opposite directions (e.g., clockwise and counterclockwise) within the tube. This may allow for rapid mixing and relatively complete oxidation or combustion of the fuel. Heat may be extracted from the heated exhaust and may be supplied to a thermal power generator to produce power. For example, the heat may be supplied to an emitter comprising a photonic crystal, which can be used to direct electromagnetic radiation to a thermophotovoltaic cell to produce power. In addition, certain embodiments are directed to relatively small burners, e.g., that can burn fuel at less than 20 ml/min to produce power. Other aspects are generally directed to various combustion methods for such burners, methods of making or using such burners, kits involving such burners, or the like.

A powder coated aluminum barbecue pit burner that burns gas in the same way that stainless steel burner tubes do, but last longer and do not rust. The use of powder coated aluminum makes the burner according to the present invention corrosion resistant. Additionally, the powder coated aluminum burner of the present invention also contain a heat sink element that prevents the temperature of the tubes from getting too high. Controlling temperature and using powder coated aluminum burners, instead of stainless steel, ensures that the burner will last longer. Another embodiment utilizes a water cooled system in connection with the heat sink element.

A burner comprising least one first passage and at least one second passage are formed in the burner, the at least one first passage and the at least one second passage are arranged such that a first fluid from an outlet of the at least one first passage and a second fluid from an outlet of the at least one second passage are mixed with each other, and the at least one first passage is configured to cause the first fluid to produce a rotational flow in a first rotation direction, and/or, the at least one second passage is configured to cause the second fluid to produce a rotational flow in a second rotation direction.
