The present invention relates to a steam generation boiler (10) comprising a bottom portion (12) and a roof portion (16) as well as walls (14) to extend vertically between the bottom portion and the roof portion, thus forming the reaction chamber (20) of the steam generation boiler, the walls (14) of which reaction chamber embody a structure comprising of steam generator pipes (30), and which steam generation boiler (10) comprises in its lower part at least one wall section (14.31) tapering towards the bottom portion (12). A first group (30.1) of steam pipes in said tapering wall section (14.31) is arranged to pass from the wall plane (Y-Z) into the reaction chamber (20) and extend from the wall plane (Y-Z) to the bottom portion (12) of the steam generation boiler on the side of the reaction chamber (20) forming a wall (11) in the reaction chamber (20), and a second group (30.2) of steam pipes is arranged to pass to the bottom portion along the wall plane (Y-Z). |
