FIELD: steam boilers.
SUBSTANCE: invention relates to design of steam boilers. Steam boiler suspended on suspensions to the upper part of the frame contains a furnace, a transition gas duct and a convective shaft, welded from gas-tight membrane screens in a screen box, which is reinforced with stiffness belts. Screen box has at least one protrusion made in the form of angular deflection of screens into the hearth. Side screens in the zone of the protrusion and its peripheral zone are equipped with vertical strips rigidly attached to the screen tubes on the outer side of the screen box.
