Title
(EN) PROCESS AND COMBUSTER FOR CARRYING OUT OXYGEN ENRICHED COMBUSTION
(FR) PROCEDE ET DISPOSITIF DE COMBUSTION POUR UNE COMBUSTION ENRICHIE EN OXYGENE
Abstract
(EN)
The invention relates to a process for combusting material, such as waste, fuel or the like, comprising the steps of: supplying material to be combusted into an oven, with removing parts, in particular a stoker oven, introducing a stream of primary combustion gas into the stoker oven, comprising at least 25 vol. % oxygen, combusting the material in the stoker oven at a predetermined temperature for a predetermined time, guiding the flue gas formed during combustion of the material away from the stoker oven, and recycling a predetermined amount of this flue gas, the secondary flue gas, back to the stoker oven.
(FR)
L'invention concerne un procédé pour assurer la combustion d'un matériau, tels que des déchets, du combustible ou similaire. Ce procédé consiste à: envoyer un matériau à brûler dans un four, doté de pièces en mouvement, en particulier, un four à chargeur automatique; introduire dans ce four automatique un courant de gaz de combustion primaire comprenant au moins 25 % en volume d'oxygène; brûler le matériau dans le four à une température prédéterminée, pendant une période de temps prédéterminée; guider le gaz brûlé formé pendant la combustion hors du four, et recycler une quantité prédéterminée de ce gaz brûlé, le gaz brûlé secondaire, renvoyé dans le four.
