Abstract
Abstract A heat exchanger comprising a feed water chamber and a steam chamber extending to a considerable extent into said water chamber in spaced relationship to the housing wall of said water chamber so that the latter has a bell-shaped contour with the skirt thereof placed in spaced relationship over a portion of the steam chamber, said water chamber being divided by a partition into two sections, one of which communicates with one end of a plurality of pipes in said steam chamber while the other water chamber section communicates with the other end of said pipes, feed water inlet and outlet means respectively communicating with said water chamber sections and being arranged in the skirt portion of said water chamber, and steam inlet and condensate outlet means being provided in said steam chamber.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
287 words
A heat exchanger for heating liquids, especially water, by means of hot media, pArticularly steam and hot gases, which includes in combination: a steam chamber comprising a first mantle forming a tubular confining wall for said steam chamber and also comprising plate means integral with one end of said mantle and closing said one end, a bell-shaped water mantle having a bottom and a skirt integral with said bottom and surrounding a portion of said first mantle in spaced relationship thereto, said bell-shaped water mantle forming a unitary part fastened exclusively at said skirt also having an annular housing section comprising an annular flange integral with and extending outwardly from said first mantle and a peripheral flange parallel to said first mantle extending toward said skirt with its end integrally connected to the free end of said skirt, partition means interposed between and connected to said plate means and said bottom of said bell-shaped water chamber and dividing the latter into two separate sections respectively provided with a feed water inlet and a feed water outlet provided in said skirt, said skirt projecting with a spacing in parallel wall relationship to the steam chamber mantle past the water inlet and water outlet, said inlet and outlet being integrally connected to said skirt between said annular flange and the bottom of said chamber and pipe means arranged in said steam chamber and having one end connected to and communicating through said plate means with one of said water chamber sections, the other end of said pipe means being connected to and communicating through said plate means with the other section of said water chamber, said steam chamber being provided with steam inlet means and with condensate outlet means.
Claim 2
Dependent Claim
287 words
A heat exchanger for heating liquids, especially water, by means of hot media, pArticularly steam and hot gases, which includes in combination: a steam chamber comprising a first mantle forming a tubular confining wall for said steam chamber and also comprising plate means integral with one end of said mantle and closing said one end, a bell-shaped water mantle having a bottom and a skirt integral with said bottom and surrounding a portion of said first mantle in spaced relationship thereto, said bell-shaped water mantle forming a unitary part fastened exclusively at said skirt also having an annular housing section comprising an annular flange integral with and extending outwardly from said first mantle and a peripheral flange parallel to said first mantle extending toward said skirt with its end integrally connected to the free end of said skirt, partition means interposed between and connected to said plate means and said bottom of said bell-shaped water chamber and dividing the latter into two separate sections respectively provided with a feed water inlet and a feed water outlet provided in said skirt, said skirt projecting with a spacing in parallel wall relationship to the steam chamber mantle past the water inlet and water outlet, said inlet and outlet being integrally connected to said skirt between said annular flange and the bottom of said chamber and pipe means arranged in said steam chamber and having one end connected to and communicating through said plate means with one of said water chamber sections, the other end of said pipe means being connected to and communicating through said plate means with the other section of said water chamber, said steam chamber being provided with steam inlet means and with condensate outlet means.
Claim 3
Dependent Claim
26 words
A heat exchanger in combination according to claim 1, in which each said steam first mantle and said water mantle has a substantially cylindrical outer contour.
