Title (EN) CONTINUOUSLY OPERABLE POWER SOURCE FUELED BY FUEL INCLUDING GAS FROM BIOMASS DOWNDRAFT GASIFIER
(FR) SOURCE D’ÉNERGIE FONCTIONNANT CONTINUELLEMENT ALIMENTÉE PAR UN CARBURANT COMPRENANT DU GAZ PROVENANT D’UN GAZÉIFIEUR À TIRAGE VERS LE BAS DE BIOMASSE
Abstract:
(EN) The invention includes a downdraft gasifier having a rotatable auger/grate extending through its reduction zone. The auger at times moves biofuel through the gasifier and at times supports it in the gasifier. A frusto-conical biomass grate funnels biomass onto the auger and is perforate for permitting the passage of gases while retaining the biomass. A guide tube surrounds the auger below the frusto-conical biomass grate. The invention also includes mixing gas or solid particulate fuel in a conduit segment that houses a mixing chamber. Fuel is fed through a fuel inlet port into the mixing chamber. High velocity combustion air from a blower is forced into the mixing chamber through a restricted orifice that generates a suction pressure for drawing gas or solid particulate fuel into the mixing chamber. A combustion chamber supply conduit delivers fuel from the mixing chamber into a burner.
(FR) La présente invention concerne un gazéifieur à tirage vers le bas ayant une étireuse/grille rotative s’étendant à travers sa zone de réduction. L’étireuse à certains moments déplace le biocarburant à travers le gazéifieur et à certains moments le supporte dans le gazéifieur. Une grille de biomasse tronconique canalise la biomasse sur l’étireuse et est perforée pour permettre le passage des gaz tout en retenant la biomasse. Un tube de guidage entoure l’étireuse en-dessous de la grille de biomasse tronconique. L’invention comprend également le mélange de gaz ou de carburant sous forme de particules solides dans un segment de conduit qui loge une chambre de mélange. Le carburant est introduit à travers un orifice d’entrée de carburant dans la chambre de mélange. De l’air de combustion à haute vitesse depuis un dispositif de soufflage est forcé dans la chambre de mélange à travers un orifice restreint qui génère une pression d’aspiration pour étirer le gaz ou le carburant sous forme de particules solides dans la chambre de mélange. Un conduit d’alimentation de chambre de combustion distribue le carburant depuis la chambre de mélange dans un brûleur.
