Definitions

  • Figures 1 to 4 relate to an embodiment of a burner in which the first reagent is combustion air and the second reaction is gaseous fuel such as methane.
  • the reagent that acts as "oxidizer” will always be considered as first reagent and the one that acts as "fuel” as second reagent".
  • the scope of the invention also includes the possibility of inverting the intake position of the fuel and of the oxidizer in the operating cavity 11.
  • the burner 1 can also use a flow of air or, alternatively, a gaseous mixture, as oxidizer. Either gaseous fuel or liquid fuel can instead be used as fuel.
  • the second feed means comprise also in this case a central lance 30 which is closed at the end through a closing element 65 which forms a nozzle 66 through which the flow of second reagent (in this case the fuel C) exits substantially in axial direction.
  • the axial position of the nozzle 66 in substance defines the intake position P2 of the second reagent.
  • the liquid fuel reaches the nozzle 66 through a feed circuit 68 which can also comprise a heater 70 (see, for example, Fig. 6 ) to take the fuel to the temperature and pressure conditions necessary to make it vaporize, after having passed through the nozzle 66, in the operating cavity 11 of the tubular element 10.
