Title (EN) A METHOD OF COMBUSTION AND A COMBUSTION PLANT FOR BURNING A COMPLEMENTARY FUEL IN THE FREE-BOARD OF A PRESSURIZED FLUIDIZED BED
(FR) METHODE DE COMBUSTION ET INSTALLATION DE COMBUSTION SERVANT A BRULER UN COMBUSTIBLE COMPLEMENTAIRE DANS LA ZONE DE REVANCHE D'UN LIT FLUIDISE SOUS PRESSION
Abstract: front page image
(EN)The invention relates to a method of combustion and a combustion plant. During the combustion in a combustion chamber (1) enclosing a pressurized fluidized bed and a space (7) located above the bed, an oxygen-containing gas is fed into the bed (4), a particulate fuel is supplied to the bed (4) and the combustion gases formed in said space during the combustion are collected. These are discharged from the combustion chamber (1) and solid material is separated from said combustion gases by means of a separating member (9). The separated solid material is recirculated (23) to the combustion chamber and a complementary fuel is supplied to said space (7) via a fuel supply member (40) for the combustion thereof in said collected combustion gases.
(FR)L'invention concerne une méthode de combustion et une installation de combustion. Lors de la combustion dans une chambre de combustion (1), qui inclut un lit fluidisé sous pression et un espace (7) au-dessus du lit, un gaz oxygéné ainsi qu'un combustible particulaire sont injectés dans le lit (4); les gaz de combustion qui se forment dans cet espace sont collectés. Tout cela est rejeté de la chambre de combustion (1); les matières solides sont séparées desdits gaz de combustion au moyen d'un élément de séparation (9). Les matières solides séparées sont remises en circulation (23) dans la chambre de combustion; l'espace (7) est alimenté en combustible complémentaire à travers un élément d'alimentation en combustible (40) pour procéder à la combustion de celui-ci dans les gaz de combustion collectés.
