  • STEAM GENERATOR
    Publication number: 20150226419
    Abstract: A steam generator includes a heat exchanger, a liquid header and a steam header. The heat exchanger is assembled by several heat exchanging subassemblies with the same structure. The heat exchanging subassembly includes a spiral heat transmission pipe bundle, a central cylinder and a sleeve. The spiral heat transmission pipes with different radii are concentrically and spirally arranged in an annular space between the central cylinder and the sleeve, to form one or more concentric heat exchanging pillar surfaces. One end of the liquid header is connected with a main water feeding pipe, and the other end of the liquid header is connected with the spiral heat transmission pipe bundle. One end of the steam header is connected with a main steam pipe, and the other end of the steam header is connected with the spiral heat transmission pipe bundle.
