Title
(EN) A SYSTEM FOR BURNING PULVERIZED SOLID FUEL AND A METHOD THEREOF
(FR) SYSTÈME DE COMBUSTION D'UN COMBUSTIBLE SOLIDE PULVÉRISÉ ET PROCÉDÉ ASSOCIÉ
Abstract
(EN)
A system for burning pulverized solid fuel and a method thereof are provided. The system comprises a combustor chamber (101), a blowpipe (104) introducing a mixture of pulverized solid fuel and a primary combustion air into the combustor chamber (101), a deflecting hood (102), and an opening (105) introducing a secondary combustion air (2°) into the combustor chamber (101). In the absence of the secondary combustion air (2°), the deflecting hood (102) forces the fuel and primary air mixture to reach the proximity of the opening for the introduction of the secondary combustion air (2°).
(FR)
L'invention concerne un système de combustion d'un combustible solide pulvérisé et un procédé associé. Le système comprend une chambre de combustion (101), un chalumeau (104) introduisant un mélange de combustible solide pulvérisé et d'un air de combustion primaire dans la chambre de combustion (101), une hotte de déviation (102) et une ouverture (105) introduisant un air de combustion secondaire (2°) dans la chambre de combustion (101). En l'absence de l'air de combustion secondaire (2°), la hotte de déviation (102) force le mélange de combustible et d'air primaire à atteindre la proximité de l'ouverture pour l'introduction de l'air de combustion secondaire (2°).
