Abstract
A large-size circulating fluidized bed boiler, comprising: a furnace having a vertical furnace center line; and at least two groups of cyclones, each cyclone of each group of cyclones having an inlet gas pass communicated with the furnace. A furnace cross section formed by outer sidewalls and located at the inlet gas pass of the cyclone is a polygon having 2×n sides, and n is a positive integer greater than 1. The polygon is axially symmetric with respect to a perpendicular bisector of each side of the polygon, and when n is 2, the polygon is a square. Triangles formed by two endpoints of an inlet of the inlet gas pass of each cyclone at the cross section and an intersection of the furnace center line and the cross section are congruent. A single flow field in communication with each of the inlet is formed in the cross section.
