A biomass fuel combustor for use in the pressurized combustion comprising of biomass fule particles to produce a pressurized exhaust gas, the combustor comprising: a cyclonic combustion chamber having a combustion region and first and second fuel inlets, the first inlet being for the entry into the chamber of gas and/or liquid secondary fuel for combustion in said combustion region and the second inlet being for the entry into the chamber of biomass fuel particles also for combustion in said combustion region, the chamber being so constructed and arranged that the heat generated by the secondary fuel combustion will, in use and at least during start-up of the combustor, promote fragmentation of the incoming biomass fuel particles.
L'invention concerne un dispositif combustor convenant particulièrement à la combustion sous pression de particules de combustible biomasse de façon à produire un gaz de carneau pressurisé. Le dispositif combustor comprend : une chambre de combustion cyclonique comportant une zone de combustion et un premier et un second orifice d'admission du combustible. En l'occurrence, le premier orifice d'admission de combustible sert à admettre, dans la chambre, un combustible secondaire liquide et/ou gazeux pour la combustion dans la zone de combustion. Par ailleurs, le second orifice d'admission sert à admettre, dans la chambre, les particules de combustible biomasse également pour la combustion dans cette zone. La chambre est conçue et agencée de manière que la chaleur produite par la combustion du combustible secondaire vienne en tout état de cause activer, pendant le fonctionnement du combustor ou au moins à son démarrage, la fragmentation de particules de combustible biomasse entrantes.
