Title (EN) OXYGEN ENHANCED COMBUSTION OF LOWER RANK FUELS
(FR) COMBUSTION DE COMBUSTIBLES DE GRADE INFERIEUR AMELIOREE PAR L'OXYGENE
Abstract: front page image
(EN)A furnace (1) that combusts fuel, such as coal, of a given minimum energy content to obtain a stated minimum amount of energy per unit of time is enabled to combust fuel having a lower energy content, while still obtaining at least the stated minimum energy generation rate, by replacing a small amount of the combustion air fed to the furnace by oxygen. The replacement of oxygen for combustion air also provides reduction in the generation of NOx.
(FR)L'invention concerne un four (1) brûlant un combustible tel que du charbon, d'un contenu d'énergie minimum donné afin d'obtenir une quantité minimum établie d'énergie par unité de temps, permettant d'utiliser un combustible à contenu d'énergie plus faible tout en obtenant au moins le taux de production d'énergie minimum établi grâce au remplacement d'une petite quantité de l'air de combustion alimentant le four par de l'oxygène. Le remplacement par de l'oxygène dans la combustion apporte aussi une réduction de production de NOx.
