Combination or steam power plant

Abstract

A combination or steam power plant is provided with an apparatus ( 20 ) with integrated steam condensation and water/water cooling. The apparatus ( 20 ) according to the invention is provided with a steam jacket ( 30 ) that encloses a steam space ( 31 ) with cooling pipes ( 33 ) for the steam condensation. The steam jacket ( 30 ) is provided at one outerside with one or more heat exchange chambers ( 41 ) for the water/water cooling, said heat exchange chambers being enclosed by a part ( 43 ) of the steam jacket ( 30 ) and in each case by a second, preferably semicircular cylindrical, second mantle part ( 41 ). For the steam condensation and water/water cooling, the apparatus ( 20 ) is provided with common water inlet and water outlet chambers ( 21, 24 ) for the coolant.

What is claimed is:  
     
         1 . Combination or steam power plant with a steam condensation and water/water cooling characterized in that the steam condensation and water/water cooling are integrated in a single apparatus ( 20 ) comprising a steam jacket ( 30 ) that encloses a steam space ( 31 ) with bundles ( 32 ) of tubes ( 33 ) for the steam condensation, and that is provided at the outer side of the steam jacket ( 30 ) with one or more heat exchange chambers for the water/water cooling, where the one or more heat exchange chamber(s) is/are surrounded by a part ( 43 ) of the steam jacket ( 30 ) and a second jacket part ( 40 ), in that the second jacket part ( 40 ) of the one or more heat exchange chamber(s) ( 41 ) is connected to the outer side of the steam jacket ( 30 ), and cooling tubes ( 42 ) for the water/water cooling are provided in the one or more heat exchange chamber(s) ( 41 ), and the integrated apparatus ( 20 ) for the steam condensation and water/water cooling is provided with one or more common water inlet chambers ( 21 ) and one or more common water outlet chambers ( 24 ) for a coolant that is intended for the steam condensation and the water/water cooling, and the cooling tubes ( 33 ) in the steam space and the cooling tubes in the heat exchange chamber for the water/water cooling each are connected via tube plates ( 29 ) with the common water inlet chamber ( 21 ) and the common water outlet chamber ( 24 ).  
     
     
         2 . Combination or steam power plant as claimed in  claim 1 , characterized in that the second jacket part ( 40 ) of the one heat exchange chamber ( 41 ) or of the several heat exchange chambers ( 41 ) is constructed cylindrically.  
     
     
         3 . Combination or steam power plant as claimed in  claim 1 , characterized in that the second jacket part ( 40 ) of the heat exchange chamber or of the several heat exchange chambers ( 41 ) is constructed in box or block shape.  
     
     
         4 . Combination or steam power plant as claimed in  claim 1 , characterized in that the integrated apparatus ( 20 ) for the steam condensation and water/water cooling is a two-pass apparatus and is provided with one or more common reversing chamber(s) for the coolant.  
     
     
         5 . Combination or steam power plant with a steam condensation and water/water cooling, characterized in that the steam condensation and water/water cooling are integrated in a single apparatus ( 20 ) comprising a steam jacket ( 30 ) that encloses a steam space ( 31 ) with bundles ( 32 ) of tubes ( 33 ) for the steam condensation, and that comprises at the outer side of the steam jacket ( 30 ) with one or more heat exchange chambers for the water/water cooling, where the one or more heat exchange chamber(s) is/are surrounded by a part ( 43 ) of the steam jacket ( 30 ) and a second jacket part ( 40 ), in that the second jacket part ( 40 ) of the one or more heat exchange chamber(s) ( 41 ) is connected with the outside of the steam jacket ( 30 ), and cooling tubes ( 42 ) for the water/water cooling are provided in the one or more heat exchange chamber(s) ( 41 ), and the integrated apparatus ( 20 ) for the steam condensation and water/water cooling is comprises one or more common water inlet chambers ( 21 ) and one or more common reversing chambers for a coolant that is intended for the steam condensation and water/water cooling, and has separate water outlet chambers for the steam condensation and water/water cooling, and the cooling tubes ( 33 ) in the steam space and the cooling tubes in the heat exchange chamber for the water/water cooling each are connected via tube plates ( 29 ) with the common water inlet chamber ( 21 ), each are connected with the common water reversing chamber ( 24 ), and each are connected with the separate water outlet chambers.
