Title
(EN) UPGRADING COAL AND OTHER CARBONACEOUS FUELS USING A LEAN FUEL GAS STREAM FROM A PYROLYSIS STEP
(FR) VALORISATION DE CHARBON ET AUTRES COMBUSTIBLES CARBONÉS À L'AIDE D'UN COURANT DE COMBUSTIBLE GAZEUX PAUVRE PROVENANT D'UNE ÉTAPE DE PYROLYSE
Abstract
(EN)
A method and apparatus for upgrading coal and other carbonaceous fuels includes subjecting the carbonaceous fuel to a pyrolyzing process, thereby forming upgraded carbonaceous fuel and a flow of lean fuel gases. Auxiliary fuel is combusted in an auxiliary fuel combustor to produce auxiliary fuel combustion gases, and the lean fuel gases are heated with the auxiliary fuel combustion gases. The heated lean fuel gases are combusted in a lean fuel combustor, thereby producing a gas stream of products of combustion, and at least a portion of the gas stream of products of combustion are directed to the pyrolyzer.
(FR)
L'invention porte sur un procédé et un appareil pour la valorisation de charbon et autres combustibles carbonés, comprenant l'opération consistant à soumettre le combustible carboné à un procédé de pyrolyse, ce qui forme de cette manière du combustible carboné valorisé et un flux de combustibles gazeux pauvres. Du combustible d'appoint est amené à brûler dans un dispositif de combustion de combustible d'appoint pour produire des gaz de combustion de combustible d'appoint et les combustibles gazeux pauvres sont chauffés avec les gaz de combustion de combustible d'appoint. Les combustibles gazeux pauvres chauffés sont amenés à brûler dans un dispositif de combustion de combustible pauvre, ce qui produit de cette manière un courant de gaz constitué de produits de combustion et au moins une partie du courant de gaz constitué de produits de combustion est envoyée vers le pyrolyseur.
