Definitions

  • the present invention relates to housing members for use in burners, and more particularly to housing members for use in burners that mix air or oxygen with a gaseous or evaporated fuel.
  • Burners that use gaseous fuel or liquid fuel are used in many applications including boilers, line healers, furnaces, other gas fired appliances, and Ln many others. Basically, these burners introduce a gaseous fuel or liquid fuel into a stream of air or oxygen. If liquid fuel is used, it must be vapourized or atomized first. The resulting flow of fuel and air or oxygen is ignited and exits the nozzle of the burner either as a visible flame or as a stream of an extremely hot gaseous mixture.
  • United States Patent No. 7,429,173 issued September 30, 2008, to Lanary et al. discloses a gas burner for use in a furnace and a method of burning gas in a furnace, especially but not exclusively a process furnace used in an oil cracking or refining process.
  • the gas burner comprises two passageways with adjacent outlets.
  • the first passageway is in fluid communication with a source of pressurised fuel gas and has an aperture through which recirculated flue gas can enter the first passageway and the second passageway is in fluid communication with a source of air.
  • fuel gas is injected into the first passageway and recirculated flue gas is thereby drawn into the first passageway so that it mixes with the fuel gas.
  • Fuel gas is partially combusted and a mixture of partially combusted fuel gas and recirculated flue gas flows up the first passageway and comes into contact with air from the second passageway and combusts.
  • the use of recirculated flue gas keeps down the level of NOx emissions and as the recirculated flue gas is sucked into the first passageway by the pressurised fuel gas flow, it is not necessary to provide complex pumping mechanisms.
  • the burner is for installation in a furnace having a mixing chamber defined by at least a furnace front wall, two side walls, a top wall and a bottom wall as well as heat transfer pipes through which a heal transfer medium flows and which are arranged on at least one of the top, bottom and side walls.
  • the burner assembly is mounted to the furnace front wall and has a tubular member with an open distal end that is located inside the mixing chamber. The other end of the tubular member is attached to the furnace front wall.
  • Several combustion air ports extend into the tubular member from the other proximal end thereof, and are coupled to a source of combustion air.
  • Several fuel gas discharge nozzles also extend into the tubular member from the other end thereof and are coupled to a fuel source.
  • Furnace gas openings formed in the tubular member are spaced apart from the distal end, are arranged about the tubular member's periphery, and are located relative to the mixing chamber so that furnace gases circulate past some of the heat transfer pipes before they reach the furnace gas openings to thereby form a m ixture of combustion air, fuel gas and furnace gas.
  • a spinner at the d istal end of the tubular member creates a recirculation zone for the mixture downstream of the spinner and the tubular member.
  • Fuel Modification Fuel Rich Reactor (FMfRR) zone gases are brought together with products from a Fuel Lean Reactor (FMR) zone in a low temperature burnout and NOx reduction reactor zone.
  • the fuel modification fuel rich reactor stabilizes combustion through recirculation of hot gases to the reactants.
  • Nitrogenous species decay reactions in the fuel rich zone controls the production of NOx.
  • the nitrogenous species from the fuel rich zone and the NOx from the fuel lean zone then react in the bumout zone at an optimal temperature and nitrogenous species mix where NOx is minimized.
  • Temperature in all zones, and in particular the burnout zone, can be controlled by furnace gas entrainment, induced flue gas recirculation, forced flue gas recirculation and active cooling by radiative and/or convective heat transfer. NOx can be even further reduced by introducing ammonia, or a like amine species, into the low temperature burnout zone. By balancing combustion and emissions control reactions over several zones, low emissions can be achieved under good flame stability, turndown, heat transfer and noise characteristics. ⁇ 00016 J It is an object of the present invention to provide a air-flow-controlling rear housing member Tor use in a burner, wherein the air-flow-controlling rear housing member causes the burner to burn fuel very efficiently.
