STEAM BOILER COMPRISING A RADIATION ELEMENT

摘要

A steam boiler has at least one water and/or steam conveying element and at least one radiation element, which is an un-cooled element, arranged in the flow of hot flue gases, such that it is convectively heated by the flue gases. The radiation element is located at a pre-determined distance from the at least one water and/or steam conveying element, wherein the pre-determined distance is arranged 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 the radiation element.
