  • the fuel supply means (28) includes an oil valve connected to the hollow pipe (26) for supplying fuel for initiating or maintaining the combustion. Air or other gas such as steam is introduced into the inner tubular member (17) through the chamber inlet tube (18) .
  • the inner tubular member (17) is substantially annular in shape having free end (23) forming a discharge outlet for air or other gas from the inner chamber (21) of the inner tubular member (17) to flow into the tubular body (11) .

  • the tubular body (11) is tapered at one side and is provided with an outlet tube (36) for final combustion.
  • the tapered shape is in a way to provide mode time for the solid combustible material (38) to burn before it flows in the outlet tube. If the hollow section of the tubular member is of one dimension there is a possibility of the material (38) flowing out at a faster rate.
  • High velocity or pressure air is introduced into the housing (13) through the air inlet tube (16) to create turbulence air within the tubular body (11) of the burner (10) which further increasing the air mixture homogeneity and considerably increases the burner combustion performance.

Abstract

L'invention concerne un brûleur comprenant un corps tubulaire qui est placé le long de l'axe longitudinal du brûleur et qui comprend un tube d'alimentation pour la réception de combustible solide. Le brûleur selon l'invention comprend également un carter à travers lequel s'étend le corps tubulaire par un passage et qui comprend un tube d'arrivée d'air pour amener de l'air à grande vitesse dans le corps tubulaire. Un élément tubulaire interne définissant une chambre intérieure ayant un orifice de décharge est placé dans le carter et comprend un tube d'alimentation de chambre (18) qui alimente la chambre intérieure en air ou en gaz. Un tube intérieur est placé dans l'élément tubulaire interne pour l'alimentation en combustible et comprend une tête de vis rotative qui imprime à l'air introduit de la chambre intérieure un mouvement en spirale le long de l'axe longitudinal vers l'orifice de décharge, entraînant ainsi le combustible solide dans le corps tubulaire.
