Abstract
(EN)
Provided is a burner apparatus for a cement kiln, which strongly forms a floating state of combustible solid waste in the cement kiln, and easily ignites the combustible solid waste in a floating state; provided also is a method for operating the burner apparatus. The burner apparatus of the present invention comprises: a solid powder fuel flow path provided with a solid powder fuel flow swirling means; a first air flow path that is disposed inside the solid powder fuel flow path and adjacent thereto and provided with an air flow swirling means; a second air flow path that is disposed on the outermost shell outside the solid powder fuel flow path and provided with an air flow straight-forwarding means; and a combustible solid waste flow path disposed inside the first air flow path. In the second air flow path, an opening constituting an air flow outlet is divided into four or more openings in the circumferential direction, and the flow rate of the air flow ejected from the openings can be controlled independently for each opening.

L'invention concerne un appareil de brûleur pour un four à ciment, qui forme fortement un état flottant de déchets solides combustibles dans le four à ciment, et allume facilement les déchets solides combustibles dans un état flottant ; l'invention concerne également un procédé pour faire fonctionner l'appareil de brûleur. L'appareil de brûleur de la présente invention comprend : un trajet d'écoulement de combustible en poudre solide pourvu d'un moyen de tourbillonnement de flux de combustible en poudre solide ; un premier trajet d'écoulement d'air qui est disposé à l'intérieur du trajet d'écoulement de combustible en poudre solide et adjacent à celui-ci et pourvu d'un moyen de tourbillonnement de flux d'air ; un second trajet d'écoulement d'air qui est disposé sur l'enveloppe extérieure à l'extérieur du trajet d'écoulement de combustible en poudre solide et pourvu d'un moyen d'acheminement droit d'écoulement d'air ; et un trajet d'écoulement de déchets solides combustibles disposé à l'intérieur du premier trajet d'écoulement d'air. Dans le second trajet d'écoulement d'air, une ouverture constituant une sortie d'écoulement d'air est divisée en quatre ouvertures ou plus dans la direction circonférentielle, et le débit du flux d'air éjecté à partir des ouvertures peut être commandé indépendamment pour chaque ouverture.
