FIELD: power engineering.
SUBSTANCE: steam boiler comprises a bottom and a roof, and also walls stretching vertically between the bottom and the roof, thus creating a reaction chamber of a steam boiler, walls of the reaction chamber include a structure comprising steam boiler pipes, besides, the steam boiler comprises in its lower part at least one section of the wall narrowing towards the bottom. The first group of steam pipes in the specified narrowing section of the wall is arranged as capable of stretching from the plane (Y-Z) of the wall into the reaction chamber and stretching from the plane (Y-Z) of the wall to the bottom of the steam boiler at the side of the reaction chamber, creating a wall in the reaction chamber, and the second group of steam pipes is made as capable of stretching towards the bottom along the plane (Y-Z) of the wall.
EFFECT: quite even heat exchange with each steam pipe in a zone of a reaction chamber.
