Definitions

  • the present invention relates to radiant burners comprising a radiant burner plate and a screen.
  • Radiant burners comprising a radiant burner plate and a screen are known e.g. from US4799879 or EP0539278 .
  • the screen together with the radiant burner plate provides the radiative output of the burner, which averages at levels around 50% efficiency.
  • the radiative output of the burners has been increased by modification of the radiant burner plate from a radiant burner plate with rows of through holes or perforations serving to channel the mixture of air and combustion agent from the rear of the plate to the radiating face, to a radiant burner plate wherein the through holes or perforations are arranged in what is nowadays called honeycomb pattern as described in e.g. US4,569,657 or US4,799,879 .
  • first and second radiant screens are produced from highly heat resistant materials such as ceramics, especially aluminium or zirconium oxide, aluminium titanate, silicon oxide, corundum or mullite, silicon carbide, silicon nitride or metal infiltrated ceramics, such as silicon-infiltrated silicon carbide.
  • the radiant screens can also be fabricated from heat-resistant materials of other nature such as e.g. materials which contain more than 50% by weight of a metal silicide, such as molybdenum disilicide (MoSi 2 ) or tungsten disilicide (WSi 2 ).
  • the radiant screens are fabricated from highly heat resistant steel grades, such as high level stainless steel grades like Kanthal APM or APMT, different grades of FeCrAl alloy designed for high temperature corrosion, Chrome/Nickel steel grades like Avesta 253 MA, 153 MA, Inconel 601, Incoloy 800HT, Incoloy MA956.
  • high level stainless steel grades like Kanthal APM or APMT
  • different grades of FeCrAl alloy designed for high temperature corrosion Chrome/Nickel steel grades like Avesta 253 MA, 153 MA, Inconel 601, Incoloy 800HT, Incoloy MA956.
  • the radiant burner plate is preferably made of a ceramic material with high temperature resistance, and excellent mechanical and thermodynamic properties such as e.g. cordierite or zirconia; partially stabilised zirconia (PSZ), alumina, silicon carbides or other high level technical ceramics. Height difference in between two levels of burner surface of the radiant burner plate is from 1 to 20 mm. More preferably, from 1 to 10 mm. Even more preferably, from 2 to 7 mm. Most preferably 5 mm.
  • the overall effect of the present invention is that the different levels in the burner surface of the radiant burner plates are at the same temperature when in use. Stated otherwise, a greater temperature uniformity of the burner surface of the radiant burner plate is attained.
  • the distance between the second radiant screen and the highest level of burner surface of the at least one radiant burner plates is between 3 and 50 mm.
  • the distance between the second radiant screen and highest level of the radiant burner plate is between 5 and 30 mm, even more preferably between 10 and 25 mm, most preferably between 15 and 20 mm.
  • the second radiant screen is positioned such that the second radiant screen follows the direction of the rows of the highest level of burner surface of the radiant burner plate.
  • the first radiant screen is preferably a metal grid.
  • the first radiant screen is an arrangement of parallel spaced round rods or square bars.
  • the first and second radiant screens are arranged in the same direction.
  • the first and second radiant screens are arranged in shifted angles with respect to one another. More preferably, the first and second radiant screens are at a 90° angle.
  • a further observed advantage of the present invention is a lower level of emissions of byproducts of combustion, such as Nitrogen Oxides or Carbon Monoxide, which is probably due to the second radiant screen which acts as an extended burner surface and provides a more complete combustion of the gas-air mixture.
  • Another aspect of the claimed invention provides a radiant burner with at least one further radiant screen in the combustion chamber.
  • the new improved radiant burner comprises a body defining a premixing chamber and a combustion chamber.
  • the premixing chamber is separated from the combustion chamber by at least one radiant burner plate which has multiple levels of burner surface.
  • the combustion chamber is further limited by a first radiant screen.
  • the radiant burner further comprises a second radiant screen in the combustion chamber. The second radiant screen is spaced from, but near the radiant burner plate(s), such that this second radiant screen acts as an extended burner surface and also heats up said at least one radiant burner plate when in use.
