ABSTRACT:
A steam generator for a steam power plant, comprising a furnace for generating hot gases and a gas pass in communication therewith, the gas pass having a sectionalized chamber for hot gas cooling. The entire gas pass together with the chamber constitute a single construction unit built up of water walls arranged one above another in height and bent in a horizontal plane so that each element of each water wall has a different number of bends. The adjacent water walls are interconnected through the top points of the bends forming sections of the entire gas pass together with the sections of the cooling chamber. This results in the formation of a system of rigidly interconnected sections which constitutes the basis of the steam generator structure featuring high rigidity and a high bearing capacity. This allows obviating any additional appliances for fastening the generator and, hence, diminishing materially the metal requirements and simplifying both the erection and operation of the steam generator.
