Title
(EN) TREATMENT OF MOIST FUEL
(FR) TRAITEMENT DE COMBUSTIBLES HUMIDES
Abstract
(EN)
A process of treating moist fuel, particularly biomass fuel, in connection with a power production process, comprises drying moist fuel (7) by means of combustion air (3), which is thereafter supplied to the power production process combustion section (1). Flue gas (11) from the combustion section, which as a result of said drying has become moisture-laden, is condensed (13) while recovering heat (15), which may be used as drying heat. In accordance with a preferred embodiment, the flue gas condensation is used to humidify (31) the combustion air.
(FR)
La présente invention concerne un procédé de traitement de combustibles humides, en particulier constitués par de la biomasse, combiné à un procédé de production d'énergie. Ce procédé comprend le séchage du combustible humide (7) au moyen d'air de combustion (3) qui est ensuite amené à la section combustion (1) du dispositif de production d'énergie. Les gaz de fumée (11) qui en proviennent sont chargés d'humidité en raison du séchage mentionné. On les condense (13) tout en récupérant de la chaleur (15) qui peut être utilisée pour le séchage. Selon un mode de réalisation préféré, la condensation des gaz de fumée est utilisée pour humidifier (31) l'air de combustion.
