CA 2434445

Fuel such as coal is combusted in a staged combustion device in a method comprising feeding into a first combustion stage of said furnace said fuel and gaseous oxidant containing more than 21 vo. % oxygen, and preferably 21.8 to 29 vol. % oxygen, at a stoichiometric ratio below that which, if the stage were operated with air as the only oxidant, would produce the same amount of Nox, and combusting said fuel with said gaseous oxidant in said combustion stage to produce combustion products and unburned fuel.

Dans le procédé décrit, un combustible tel que le charbon est brûlé dans un dispositif de combustion étagé. Ce procédé consiste à introduire dans le premier étage de combustion dudit fourneau le combustible ainsi qu'un oxydant gazeux contenant plus de 21 % en vol. d'oxygène, et de préférence de 21,8 à 28 % en vol. d'oxygène, à une proportion stoechiométrique en dessous de laquelle une quantité identique de NOx serait produite si l'étage n'était alimenté qu'avec de l'air en tant qu'unique oxydant, et à brûler ledit combustible avec ledit oxydant gazeux dans ledit étage de combustion de manière à obtenir des produits de combustion et du combustible imbrûlé.
