摘要： According to the present disclosure, a flat-flame nozzle is provided for producing a flat flame in a flame chamber included in a burner assembly. The flat-flame nozzle is configured to conduct fuel from a fuel supply to an ignition zone in the flame chamber. In some illustrative embodiments, the flat-flame nozzle is also configured to conduct oxygen from an oxygen supply to the ignition zone to produce a combustible oxygen-fuel mixture in the flame chamber. In illustrative embodiments, a removable first plate-separation border frame is positioned to lie between a first lower plate and a companion first upper plate. This border frame is configured to cooperate with those plates to form in the flat-flame nozzle a fuel-discharge outlet and a fuel-transport passageway communicating with the fuel-discharge outlet.

摘要： A perforated flame holder and burner including a perforated flame holder provides reduced oxides of nitrogen (NOx) during operation. The perforated flame holder includes a pattern of elongated apertures extending between a proximal and a distal surface of the flame holder relative to a fuel nozzle. The perforated flame holder can provide a significantly reduced flame height while maintaining heat output from the burner.

摘要： The invention relates to a submerged burner (1) for a glass-melting or rock-melting furnace, comprising - a plurality of aligned injectors, each injector comprising a mixing chamber (2) in the shape of a cylinder, with an ejection orifice (11), a fuel supply duct (3) and an oxidizer supply duct (4) opening into the mixing chamber at the jacket of the cylinder in a direction that causes the fuel and the oxidizer to flow tangentially in relation to the jacket of the cylinder, and - a system of ducts (12) allowing a cooling fluid to be circulated inside the burner and, for preference - on either side of the alignment of injectors (1) and arranged parallel to and along these, solid metal flanks (5) extending up from the injectors, and - protective walls (6), situated on the tops of the solid metal flanks (5). The invention also relates to a furnace comprising such a submerged burner and to a method for melting glass or rock using such a furnace.

摘要： This invention refers to a process for achieving the total combustion of fuels, which will totally reduce the pollution of the atmosphere, will solve, in great part the climatic crisis, will stop greenhouse effect the humanity is facing, as well global warming. The field of use of the invention is very wide, for example at engines of the vehicles, the engines with propulsion of the airplanes, the engines of the ships and all the equipments for transporting and combustion of heat and electricity and this process involves using several types of injectors on the basis of compressed air on which the pipe of fuels are mounted, and the air compressed at a pressure of 5 at∞ ATM, through the vacuum created in the pipe of fuel will absorb the fuel in the mass of compressed air, in order to achieve total combustion and the number of compressed air molecules necessary to the total combustion of one molecule of hydrocarbon, for each type of hydrocarbons, are selected from Table 1.

摘要： A gas burner apparatus for discharging a mixture of fuel gas, air and flue gas into a furnace space of a furnace wherein the mixture is burned and flue gas having a low content of nitrous oxides and carbon monoxide is formed is provided. The burner tile includes at least one gas circulation port extending though the wall of the tile. The interior surface of the wall of the tile includes a Coanda surface. Fuel gas and/or flue gas conducted through the gas circulation port follows the path of the Coanda surface which allows more flue gas to be introduced into the stream. The exterior surface of the wall of the tile also includes a Coanda surface for facilitating the creation of a staged combustion zone. Also provided are improved burner tiles, improved gas tips and methods of burning a mixture of air, fuel gas and flue gas in a furnace space.
