Abstract

a. Procédé d'injection d'un ou plusieurs types de particules solides dans un brûleur à suspension fluide. b. Procédé caractérisé en ce qu'il comprend les différentes étapes consistant à introduire les particules solides par une ou plusieurs conduites placées au-dessous de la plaque de distribution du brûleur à suspension fluide; à injecter du gaz à grande vitesse dans les conduites de façon qu'il sorte par un ou plusieurs orifices espacés dans le bas des conduites, de manière à entraîner les particules solides dans le courant de gaz; et à guider le gaz et les particules solides entraînées pour les faire sortir vers le haut à travers au moins une chambre traversant la plaque de distribution et sortant dans l'enceinte de suspension fluide en un point situé au-dessus de la plaque de distribution, de manière à obtenir une distribution uniforme des particules solides dans toute la zone de suspension fluide c. L'invention s'applique dans le domaine des brûleurs de chaudières à vapeur.
