Abstract
A circulating fluidized bed boiler includes a vertically extending furnace, a separator unit, and an exhaust gas channel connected to the separator unit via a cross over duct. The exhaust gas channel includes a first vertically extending pass, a horizontally extending pass, and a second vertically extending pass. The first vertically extending pass, the horizontally extending pass, and the second vertically extending pass are arranged successively in the gas flow direction such that the horizontally extending pass is configured to connect the first vertically extending pass and the second vertically extending pass with each other. The horizontally extending pass is arranged below the separator unit, which is arranged between the first vertically extending pass and the second vertically extending pass.
