Abstract

Procédé de combustion de combustible dans une chambre de combustion cylindrique, comprenant, dans cette chambre de combustion, une projection, à partir d'un brûleur, d'un jet de combustible solide pulvérulent déplacé par un air de transport, et éventuellement d'un flux d'air primaire, et une alimentation en un gaz comburant suivant un sens de propagation de manière à former un courant de gaz comburant autour du jet de combustible projeté par le brûleur, à une température occasionnant une combustion du combustible, le jet de combustible solide présentant une composante axiale de projection dans un même sens que ledit sens de propagation du gaz comburant dans la chambre de combustion cylindrique et le rapport entre débit spécifique de quantité de mouvement du brûleur et débit spécifique de quantité de mouvement du gaz comburant étant égal ou inférieur à 1,0 et supérieur à zéro.A process for the combustion of fuel in a cylindrical combustion chamber, comprising, in this combustion chamber, a projection, from a burner, of a jet of pulverulent solid fuel displaced by a transport air, and optionally of a flow of primary air, and a supply of an oxidizing gas in a direction of propagation so as to form a stream of oxidizing gas around the fuel jet projected by the burner, at a temperature causing combustion of the fuel, the fuel jet solid having an axial component of projection in the same direction as said direction of propagation of the oxidant gas in the cylindrical combustion chamber and the ratio between the specific flow rate of the burner momentum and the specific flow rate of the oxidizer gas momentum being equal or less than 1.0 and greater than zero.
