Abstract

A heat exchanger having an arrangement of heat transfer surfaces and a pair of vertical steam/water separators structurally interconnected to one another to provide an integral support structure for the heat exchanger. The structural interconnection includes upper and lower structural members extending between the pair of vertical steam/water separators. The upper and lower structural members include headers, and an arrangement of heating surface which extends between and is fluidically connected to the headers. A structural support framework surrounds the heat exchanger for bottom support thereof, the framework providing structural support and rigidity for the heat exchanger and a means by which the heat exchanger can be picked up and lifted for placement at a desired location.

Claims

         2 . The heat exchanger of  claim 1 , wherein the structural interconnection includes upper and lower structural members extending between the vertical steam/water separators. 
     
     
         3 . The heat exchanger of  claim 2 , wherein the upper and lower structural members are formed of heavy wall pipe. 
     
     
         4 . The heat exchanger of  claim 3 , including a pair of spaced partition walls disposed in crosswise fashion within the heavy wall pipe to form a central portion therein. 
     
     
         5 . The heat exchanger of  claim 4 , wherein the central portion is a header. 
     
     
         6 . The heat exchanger of  claim 5 , wherein said portion of the heat transfer surfaces extends between and is fluidically connected to the headers of the upper and lower structural members. 
     
     
         7 . The heat exchanger of  claim 1 , including a support structural framework having a top, a bottom and opposing lengthwise sides surrounding the heat exchanger for bottom support thereof. 
     
     
         8 . The heat exchanger of  claim 7 , wherein the structural framework is in a shape of a rectangular parallelepiped. 
     
     
         9 . The heat exchanger of  claim 7 , wherein the bottom of the structural framework is comprised of horizontally extending lateral and longitudinal beams. 
     
     
         10 . The heat exchanger of  claim 9 , wherein the lateral and longitudinal beams intersect one another to form a grid-like structure. 
     
     
         11 . The heat exchanger of  claim 10 , including a lattice of obliquely-disposed web members positioned between intersecting longitudinal and lateral beams. 
     
     
         12 . The heat exchanger of  claim 9 , wherein the bottom of the structural framework includes four parallel spaced longitudinal beams 
     
     
         13 . The heat exchanger of  claim 12 , including two pairs of parallel spaced lateral braces intersecting the inner two of said four longitudinal beams to form support bases for the steam/water separators. 
     
     
         14 . The heat exchanger of  claim 13 , wherein each of the vertical steam/water separators includes a plurality of pedestal feet positioned at the lower end of the separator and fixedly secured to a respective one of the support bases. 
     
     
         15 . The heat exchanger of  claim 7 , wherein each of the opposing lengthwise sides of the structural framework has two pairs of parallel spaced vertical beams located at opposite ends of the structural framework and one pair of parallel spaced longitudinal beams intersecting the vertical beams and located at the upper end of each of the opposing sides. 
     
     
         16 . The heat exchanger of  claim 15 , including a lattice of obliquely-disposed web members positioned between each pair of vertical beams and the pair of longitudinal beams.
