Abstract
Abstract A waste heat boiler in which a support frame which is symmetrical about a central vertical axis has planar wall members supported thereon and forming an enclosure. Each wall member is symmetrical about a central axis and has flow passages with symmetrically located inlets and outlets. Each wall member is reversible on the support frame to present either face to the inside of the boiler and at least some of the wall members are identical so as to be receivable in several places on the frame. The boiler also has a ceiling member which is tiltable and which is also reversible.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
196 words
A boiler, especially a waste heat boiler comprising; a dimensionally stable vertical support frame having an inlet at the bottom and an outlet at the top, planar wall members mounted on said frame and connected along the adjacent edges to form an enclosure supported by said frame, said enclosure being symmetrical about the central vertical axis of said frame, each wall member being formed with liquid flow passages therein, inlet means and outlet means for the flow passages of each wall member, said inlet means and outlet means being symmetrically located in respect of the vertical central plane of the respective wall member, header means for each wall member symmetrically located in respect of the central axis of said frame and of the respective wall member and connected to the inlet means and outlet means of the respective wall member, and connecting means connecting the wall members to said frame and also symmetrically located in respect of the central axis of the respective wall members, whereby each wall member can be reversed about the said central axis thereof for selectively presenting the two sides thereof to the inside of the enclosure formed by said wall members.
Claim 2
Dependent Claim
196 words
A boiler, especially a waste heat boiler comprising; a dimensionally stable vertical support frame having an inlet at the bottom and an outlet at the top, planar wall members mounted on said frame and connected along the adjacent edges to form an enclosure supported by said frame, said enclosure being symmetrical about the central vertical axis of said frame, each wall member being formed with liquid flow passages therein, inlet means and outlet means for the flow passages of each wall member, said inlet means and outlet means being symmetrically located in respect of the vertical central plane of the respective wall member, header means for each wall member symmetrically located in respect of the central axis of said frame and of the respective wall member and connected to the inlet means and outlet means of the respective wall member, and connecting means connecting the wall members to said frame and also symmetrically located in respect of the central axis of the respective wall members, whereby each wall member can be reversed about the said central axis thereof for selectively presenting the two sides thereof to the inside of the enclosure formed by said wall members.
Claim 3
Dependent Claim
46 words
A boiler according to claim 1 in which the location of the inlet means and outlet means and header means and connecting means is identical for at least some of said wall members for permitting the placement thereof in any of several positions on said frame.
Claim 4
Dependent Claim
35 words
A boiler according to claim 1 in which each wall member is formed of pipes having fins thereon, the fins of adjacent pipes in a wall member being joined together to form the wall member.
Claim 5
Dependent Claim
28 words
A boiler according to claim 3 in which the fins at the adjacent edges of the wall members are joined together to form the enclosure on the frame.
Claim 6
Dependent Claim
57 words
A boiler according to claim 1 in which the enclosure includes ceiling means at the top, said ceiling means including at least one set of horizontal finned pipes, and a distributor pipe connected to said finned pipes at one end, said set of finned pipes being rotatable as a unit about the axis of said distributor pipe.
Claim 7
Dependent Claim
39 words
A boiler according to claim 5 in which said set of finned pipes and the distributor pipe are symmetric about an axis perpendicular to the axis of the distributor pipe to permit inversion of the set of finned pipes.
Claim 8
Dependent Claim
41 words
A boiler according to claim 6 in which the ceiling means includes two sets of finned pipes and a distributor pipe for each set of finned pipes at the end of the respective set which is remote from the other set.
Claim 9
Dependent Claim
67 words
A boiler according to claim 5 in which said set of finned pipes comprise hairpin shaped pipes with the inlets and outlets in spaced relation, said distributor pipe having a longitudinal partition thereon dividing the inside thereof into separate fluid passages, the inlets of said finned pipes being connected to one of said fluid passages and the outlets being connected to the other of said fluid passages.
