Abstract
A bottom-supported boiler includes a boiler pressure body having a rectangular horizontal cross section formed by joining four planar water tube walls pairwise together so as to form four corner sections, and a support construction. The support construction includes four vertical columns vertically supported to the ground, the vertical columns being arranged outside of the boiler pressure body so that adjacent to each of the corner sections is arranged one of the four vertical columns. Each of the vertical columns is attached to the respective corner section so that vertical loads of the boiler pressure body are balanced by the four vertical columns.
