Abstract

A wall construction for a boiler arrangement (10). The boiler arrangement is formed of at least a furnace (12) and a separator (16). The furnace has a grid, a bottom part, and an upper part. The separator is arranged by conduits (70) in flow communication with both the upper part and the bottom part of the furnace. The conduits, together with the separator, form an external circulation of bed material. The upper part of the furnace has four vertical walls, and the bottom part of the furnace has a height and four walls extending from the grid up to the vertical walls. The wall construction includes at least one hollow beam being attached to a wall of the bottom part of the furnace and extending substantially over the entire height of the bottom part, and the at least one hollow beam being in flow communication with the external circulation for returning bed material into the furnace.
