The present invention relates to a system for dry extracting / cooling heavy ashes and for controlling the combustion of high unburnt content residues, allowing to: extract heavy ash from the boiler bottom (12), foster and adjust post-combustion on the extractor belt (14) by combined use of comburent hot air and inert combustion fumes, already available in boiler, cool the ashes present on the belt and optionally re- circulating them - all or in part - in boiler, along with the fraction of light ashes of higher unburnt content.
La présente invention concerne un système d'extraction sèche/de refroidissement de cendres lourdes et de commande de la combustion de résidus à haute teneur non brûlée, permettant : d'extraire les cendres lourdes du fond de la chaudière (12), de placer et d'ajuster la post-combustion sur la courroie d'extraction (14) par l'utilisation combinée d'air chaud comburant et de fumées de combustion inertes, déjà disponibles dans la chaudière, de refroidir les cendres présentes sur la courroie et éventuellement de les recycler - toutes ou une partie d'entre elles - dans la chaudière, avec la fraction de cendres légères à teneur non brûlée supérieure.
