Scope Notes

Glossary: Air a mixture of gases containing free oxygen and able to promote or support combustion. Primary air air supplied to the burning fuel (e.g. together with the fuel) in order to liberate combustible gases. Secondary air air supplied to the combustible gases liberated by the primary air in order to complete their combustion. The expression "secondary air" covers "tertiary air" etc. Burner Burners a device by which fluid fuel or solid fuel suspended in air is passed to a combustion space where it burns to produce a self-supporting flame. A burner includes the means for feeding air that are arranged in immediate connection with a fuel feeding conduit, for example concentric with it. Combustion a heat-producing sequence of chemical reactions between a burnable substance and molecular oxygen, e.g. in air, in most cases generating light in the form of flames or a glow. Combustion chamber combustion chambers a chamber in which fuel is burned to establish a self-supporting fire or flame and which surrounds that fire or flame. Combustion space the zone downstream of the fuel (and, where applicable, air) outlet where the reaction takes place between air and fuel. Pilot flame a small flame that is lit or kept alight in order to provide ignition to a more powerful burner. Retention flame a small flame that is kept alight in order to maintain the uninterrupted operation of a more powerful burner. Torch Torches a burner fired with fuel gas and oxygen and specially adapted to apply heat to a workpiece, for example for use in welding, cutting or brazing. | Limiting references: Candles Combustion in a fluidised bed of fuel or other particles Apparatus in which combustion takes place in pulses influenced by acoustic resonance in a gas mass Igniting of burners | Application references: Flame throwers for destroying noxious animals or plants Bakers' ovens Cooking devices, e.g. travelling cookers or barbecues , Soldering , Gas flame welding or cutting Cutting, scarfing, or desurfacing by applying flames Using burners in chemical vapour deposition Heating boreholes or wells with burners Using burners for regenerating exhaust gas filters Gas-turbine plants Jet-propulsion plants Using burners for ignition of internal combustion engines , Incandescent mantles Non-electric portable lighting devices Non-electric non-portable lighting devices Arrangements of mantles or other incandescent bodies on lighting burners Details of lighting devices employing combustion as light source Steam boilers Arrangement of burners in combustion apparatus Methods or apparatus specially adapted for combustion of waste or low-grade fuels. e.g. waste oil, waste liquors or waste gases Lighters containing fuel Ignition using burners , Generating combustion products of high pressure or high velocity, e.g. gas turbine burners Stoves or ranges for liquid or gaseous fuels Fluid heaters having heat-generating means, e.g. heating boilers Arrangement of burners in fluid heaters Arrangement of burners in furnaces or ovens for heat treatment Using burners for cleaning heat exchangers Flame-throwers for attack or defence
