Abstract
A boiler construction includes a boiler pressure body having a bottom and a roof at a height H from the bottom and at least four planar watertube walls forming a polygonal horizontal cross section with at least four corner sections, and a rigid support steel structure, the boiler pressure body being supported to the rigid support steel structure at a height between the bottom and roof. A vertical corner column is attached exteriorly to at least four of the at least four corner sections at a height region between the bottom and roof, and the supporting of the boiler pressure body is provided by supporting each of the vertical corner columns to the rigid support steel structure at a height from 0.1 H to 0.9 H from the bottom so as to balance vertical loads of the boiler pressure body.
