摘要
The circulating fluidized bed boiler 1 comprises a furnace 50, a loop seal 5, and a loop seal heat exchanger 10 arranged in the loop seal 5. The loop seal heat exchanger 10 includes at least the inlet chamber 100, the bypass chamber 200 and the first heat exchange chamber 310, heat exchanger pipes 810 arranged in the first heat exchange chamber 310, And a primary particle outlet 610 for discharging the layer material from the first heat exchange chamber 310. In the primary particle outlet 610, the first portion 611 of the primary particle outlet 610 has a first height h1 and a first width w1, and a first height h1 versus a first width ( It has at least a first portion 611 and a second portion 612 separated from each other by a barrier element 401 in such a way that the ratio h1/w1 of w1) is less than 0.5 or more than 2. With the use of the circulating fluidized bed boiler 1, the fluidized gas and bed material are discharged from the first heat exchange chamber 310 through the primary particle outlet 610.
