Definitions

  • coolant is supplied to the inlet 5 of the cooling jacket 3, this coolant departing from the jacket 3 through the outlet 7.
  • Oxygen is supplied through the inlet 17 to the oxygen chamber 21, this oxygen departing therefrom through the nozzle 13, and fuel, for example natural gas, is supplied through the conduit 31 where it is dissipated in the chamber 27 and departs therefrom through the nozzle 25, 26.
  • fuel for example natural gas
  • oxygen is supplied to the oxygen chamber 21 and fuel through the conduit 31 in such volumes and at such proportions that there will be obtained stoiciometric combustion with a suitable flame size.
  • the burner then functions as a conventional oxy-fuel burner.

Abstract

Procédé de production d'une flamme fortement oxydante et brûleur correspondant, celui-ci comportant un corps central (9) pourvu d'une buse centrale à oxygène (23) et d'au moins une buse à combustible (25, 26), un boîtier (1) entourant le corps central (9), au moins une buse périphérique à oxygène (13) située excentriquement par rapport à la buse à combustible (25, 26) et une chambre à oxygène (21) située hors du corps central (9), toutes les buses (23, 25 26, 13) étant au moins pratiquement parallèles. La buse centrale à oxygène (23) et la buse périphérique à oxygène (13) sont raccordées à différentes sources d'oxygène, ce qui permet à la source raccordée à la buse centrale à oxygène (23) de fournir une pression plus élevée que la pression de l'autre source. De préférence, la buse centrale à oxygène (23) a la forme d'une tuyère de Laval. Quand on alimente le brûleur uniquement avec de l'oxygène, il peut être utilisé comme lance à oxygène. Dans ce cas, l'oxygène alimente, de préférence, uniquement la buse centrale à oxygène (23).
