SUSPENDED STEAM BOILER Russian patent published in 2009 - IPC F22B37/12 

FIELD: heating systems.

SUBSTANCE: invention is intended for attaching heating surfaces and can be used in heat engineering. Boiler includes the top part having the wall made of vertical tubes and vertical connecting straps formed therebetween, and the bottom part supported on the wall, which has the wall made of inclined tubes and inclined connecting straps formed therebetween. Inclined tubes have upper end sections which end on the wall upper edge and are deflected relative to each other. Along the wall upper edge there provided is the connecting strap which is equipped with many vertical elbow pipes with connection branches protruding from the connecting strap and vertical branches fixed on the connecting strap and welded to vertical tubes, and many inclined elbow pipes with connection branches protruding from the connecting strap and inclined branches fixed on the connecting strap and welded to the end sections of inclined tubes. The connecting strap is welded to the wall under the inclined branches of inclined elbow pipes along inclined branches and above end sections of inclined tubes along end sections. Vertical branches of vertical elbow pipes of the connecting strap are welded to vertical wall tubes.

EFFECT: reducing constructional costs for suspension of the boiler bottom part.
