摘要:
Dans un procédé de production de courant et de chaleur au moyen d'une installation de chauffe à lit fluidisé sous pression (1), de l'eau est introduite dans le lit fluidisé, et la vapeur d'eau engendrée, de concert (10) avec le gaz de fumée, est acheminée vers des appareils montés en aval pour dépoussiérage (12), détente (13) productrice d'un rendement, et refroidissement (15). L'introduction d'eau permet d'accroître la puissance volumique du lit fluidisé et facilite la régulation.

In a method wherein the fuel is homogeneously mixed with an inert material to be burnt in a swirling motion chamber, it is proposed that the mixing be done outside the combustion chamber (2) and introduced into the latter. Thereby, it is possible to prepare the fuel independently of the combustion process and of the desired thermodynamic conditions in the combustion chamber. The device for implementing such method comprises an ash evacuation channel (4) which opens out at its lower portion in a supply channel (8) for the swirling bed (2), said channel being supplied with fuel (6) and gas (10, 11).

Dans un procédé dans lequel le combustible est mélangé de façon homogène avec un matériau inerte pour être brûlé dans une chambre à mouvement tourbillonnant, il est proposé que le mélange soit effectué en dehors de la chambre de combustion (2) et introduit dans celle-ci. Par cette mesure, il est possible de rendre la préparation du combustible indépendante du procédé de combustion et des conditions thermodynamiques souhaitées dans la chambre de combustion. L'installation pour la mise en oeuvre de ce procédé comporte un canal d'évacuation des cendres (4) qui débouche à sa partie inférieure dans un canal d'alimentation (8) pour la sole de combustion (2), ce canal étant alimenté en combustible (6) en en carburant (10, 11).
摘要:
The invention relates to a process and a device for processing of biological residual material, in particular sludge. The process according to the invention is characterised by the following procedural steps: de-watered sludge is dried in a fluidised bed dryer until a maximum water content of 10 % is obtained; the dried sludge is gasified in a fluidised bed gasifier subject to a lack of oxygen thereby producing product gas; a block-type thermal power station is operated using the product gas; the waste heat from the fluidised bed gasifier and the block-type thermal power station is supplied to the fluidised bed drier or the fluidised bed gasifier by closed pipe systems. The device according to the invention comprises a fluidised bed drier, a fluidised bed gasifier and a block-type thermal power station, a de-watering device generally being connected upstream of the fluidised bed drier.
