HIGH PRESSURE AIR ATOMIZING BURNER [4 records]

Record 1 1990-10-05

English

Subject field(s)
  • Burners and Steamfitting
  • Gas and Oil Heating
OBS

Air atomizing burners are designed to use compressed air at either high or low pressure for atomization. The high pressure burner is nearly identical with the steam atomizing burner in design and application. Some burners operate well with either medium.

OBS

Pulvérisation par l'air sous moyenne pression. Elle est utilisée pour des brûleurs dont les débits s'échelonnent entre 0.5 et 250 kg/h, mais la gamme la plus fréquente s'étend de 0,5 à 50 kg/h. La figure 19 (p. 20) représente deux exemples de réalisation, mais il existe beaucoup d'autre modèles qui permettent d'obtenir des résultats identiques. Tous peuvent donner à volonté des flammes courtes (pression et quantité d'air primaire voisines du maximum indiqué dans le tableau XIII, p. 21) ou longues (valeurs inférieures du tableau), convenant pour l'équipement: - de la plupart des fours industriels de petite ou moyenne puissance (pour fusion, forge, traitements thermiques, bains de trempe, cuissons céramiques, arches à recuire des verreries, ...); - des petits générateurs de vapeur (1 à 20 m [carré] de surface de chauffe); - des chaudières de chauffage central d'une puissance inférieure à 50 000 kcal/h, ou difficilement adaptables à la chauffe au mazout.

The high pressure atomizing type gun... burner supplies oil to the atomizing nozzle at 689 to 2067 kPa. A blower is used to supply the air for combustion, and a damper or other adjustable means regulates the air supply at the burner. Ignition is usually established by a high voltage electric spark which may be intermittent, sometimes called constant ignition(on when the burner motor is on) or interrupted(on only to start combustion). Typically these burners fire into a combustion chamber in which negative draft is maintained.

Air atomizing burners are designed to use compressed air at either high or low pressure for atomization. The high pressure burner is nearly identical with the steam atomizing burner in design and application. Some burners operate well with either medium.

OBS

With high-pressure gun-type burner oil and air do not make contact until they both have actually left the burner and entered the firebox.

  • Fumisterie et brûleurs
CONT

Brûleurs à pulvérisation directe. (...) Le niveau de pression utilisé pour la pulvérisation (15 m bar à 1 bar et plus) différencie les brûleurs en basse, moyenne et haute pression. Plus la pression est élevée, plus le débit de l'air pulvérisant est faible et plus il est nécessaire de faire apport d'air comburant (le ventilateur doit être à même de fournir l'air primaire et l'air secondaire). Pour les brûleurs à haute pression qui équipent les chaudières à tube foyer et à tube de fumée, le ventilateur est généralement dissocié du brûleur.

Return Flow Mechanical Atomizing Oil Burners. This [commercial-industrial oil] burner is a modification of a mechanical atomizing burner; atomization is accomplished by oil pressure alone.... The burner was developed for use in large installations such as on shipboard and in electric generating stations.... It is also used for firing large hot water boilers compressed air is too expensive for atomizing oil in large burners.... Wide range is accomplished by use of a return-flow nozzle which has a swirl chamber just ahead of the orifice or sprayer plate. Good atomization is attained by maintaining a high rate of oil flow and high pressure drop through the swirl chamber. The excess oil above the load demand is returned from the swirl chamber to the oil storage tank or to the oil pump suction. Control of burning rate is accomplished by varying the oil pressure in both the oil inlet and the oil return lines.

OBS

This is a register-type burner similar to the mechanical atomizing burners.

OBS

Pulvérisation mécanique à retour. Dans le but d'obtenir une plage de réglage suffisante, le pulvérisateur mécanique est complété d'un circuit de retour qui ramène au réservoir une partie du combustible prélevé dans le pulvérisateur même.
