Abstract
A water-cooled column () used in a circulating fluidized bed boiler furnace is disclosed, wherein the water-cooled column is formed by connecting membrane water-cooled walls (). The water-cooled column () includes a lower section (A), an upper section and a transition section. The lower section (A) is a single column and is provided with inner secondary air ports () on a side wall thereof. The upper section includes a plurality of sub-columns (B, C). The membrane water-cooled walls at the lower section (A) extend to the upper section through the transition section. Each of the sub-columns (B, C) is formed by connecting extension portions extending upward from respective membrane water-cooled walls () in the membrane water-cooled walls (), which are connected to form the lower section (A), and the plurality of sub-columns (B, C) are separated from each other.
