Abstract
A circulating fluidized bed reactor is provided, based on a multi-inlet cyclone, comprising an elongated riser channel (5; 25), which has a lower portion (4; 24) and an upper portion, whereby solid matter and fluidization gas can be fed into the riser through the lower portion (4; 24). In the upper portion of the riser channel, there is a multi-inlet cyclone comprising a separation chamber (7; 27), with a set of guide vanes (6; 26), a central tube (8; 28) connected to the separation chamber, an outlet (11; 31) and a return channel (10; 30). The set of guide vanes (6; 26) of the multi-inlet cyclone, the cyclone chamber (7; 27) and the central tube (8; 28) are annularly fitted about the riser channel (5; 25). The configuration of the circulating fluidized bed reactor allows for advantageous flow dynamics and the reactor may be used as a dryer or steam boiler.
