The supporting beam arrangement (14) comprises a horizontal second supporting beam (20) defining two opposite ends (22) that are supported to the first supporting beams (18), the second supporting beam extending through the flue gas duct (10) that is supported to the second supporting beam. At least one or each one of the first supporting beams comprises an opening (24), in which opening one of the two opposite ends (22) of the second supporting beam is placed to rest on the first supporting beam (18). A power boiler (50) comprises the supporting beam arrangement (14), the flue gas duct (10) and the support frame (16).
