Tube bundle steam generator for recovery of waste heat

The invention waste heat recovering relates to a vascular-type steam generator, the housing 20 is the moving space 21 for the working fluid moves within the formation, is provided inside the housing 20, the heat source moving inside a plurality of tube 30 and the housing 20 includes a plurality of partition walls 40, the plurality of barrier ribs 40 are installed at predetermined intervals inside which is shaped to correspond to the entire cross-section of the housing 20 It is formed in, and a lower portion of the plurality of partition walls 40 arranged to form a configuration in which the moving passage (42) to move the working fluid. By using the waste heat recovering vascular model steam generator as described above, the present invention moves the working fluid through the moving passage provided with a plurality of barrier ribs, and formed on the lower portion of each partition wall in the shape corresponding to the entire housing cross section in the housing thereby, the working fluid is performed by a plurality of heat exchange tubes and the whole is installed on the inner housing improves the heat transfer performance.
