Abstract

A steam boiler (1) comprising at least one water and/or steam conveying element (30, 60) that is heated by the hot flue gases in the boiler characterized in that the steam boiler (1) comprises at least one radiation element (70) wherein; said radiation element (70) is an un-cooled element; said radiation element (70) is arranged in the flow of hot flue gases (12) such that it is convectively heated by the flue gases; said radiation element (70) is located at a pre-determined distance from said at least one water and/or steam conveying element (30, 60) wherein said predetermined distance is adapted such that the flow of hot flue gases between the radiation element and the water and/or steam conveying element is unhindered, and such that the water and/or steam conveying element is heated by heat radiation from said radiation element.
