<p>A method and an arrangement for separating fluidized bed medium from flue gas flow in a circulating fluidized bed boiler. The invention is based on forming at least one vigorous vortex (19) in the top part (2) of the furnace (1) by means of at least one gas jet blown toward the centre of the furnace (1), the vortex bringing the particles into furnace (1) corners or to separate separator devices in the vicinity of the walls by means of centrifugal force. The vortex or vortices (19) formed must be shifted sideways from the centre axis of the furnace (1) such that no calm area with no particle separation is formed in the middle of it.</p> |
