Multi-half pipe heat exchange system for electric arc, metallurgical or refining furnaces and system thereof
A cooling assembly for cooling exhaust gases emitted from a steel-making furnace includes a plate configured to be coupled to the furnace. The plate has a first surface and an opposing second surface. The assembly includes a body having a defined length and a cross-sectional shape having a thickness defined between an outer surface and an inner surface thereof. The body includes a first mounting end and a second mounting end, where the first mounting end is mounted to the first surface at a first angle greater than 0°. The second mounting end is also mounted to the first surface at a second angle greater than 0°, and the second mounting end is spaced from the first mounting end. A conduit is defined between the inner surface and first surface for a cooling fluid to flow therethrough.
1. A cooling assembly for cooling exhaust gases emitted from a steel-making furnace, comprising:
a body configured to be coupled to a mounting surface of the furnace, the body comprising a defined length and a cross-sectional shape having a thickness defined between an outer surface and an inner surface thereof, the body including a first mounting end and a second mounting end;
wherein, the body comprises a first portion, a second portion, and an intermediate portion integrally formed between the first and second portions;
wherein, the first mounting end is integrally formed in the first portion, the first mounting end comprising a first end surface which is angularly coupled to the mounting surface;
wherein, the second mounting end is integrally formed in the second portion, the second mounting end comprising a second end surface which is angularly coupled to the mounting surface at a location spaced from the first mounting end;
wherein the mounting surface includes an opening formed therein, the body being coupled to the mounting surface such that the intermediate portion is aligned with the opening;
wherein, a first fluid conduit is defined between the inner surface of the first portion and the mounting surface;
wherein, a second fluid conduit is defined between the inner surface of the second portion and the mounting surface.
2. The cooling assembly of claim 1 , wherein the intermediate portion comprises a defined width between the first portion and the second portion, where the intermediate portion comprises a substantially flat surface disposed in contact with the mounting surface over the defined width.
3. The cooling assembly of claim 1 , wherein:
the first portion is in contact with the mounting surface at a first contact point;
the second portion is in contact with the mounting surface at a second contact point;
the first contact point and second contact point each being a single point of contact at any location along the length of the body.
4. The cooling assembly of claim 1 , wherein:
the first portion is in contact with the mounting surface at a first contact point;
the second portion is in contact with the mounting surface at a second contact point;
the intermediate portion is in contact with the mounting surface along its width, where the contact between the intermediate portion and mounting surface is greater than a combined contact of the first portion and second portion with the mounting surface.
5. The cooling assembly of claim 1 , wherein the body is formed from steel, iron, nickel or an aluminum-bronze alloy.
6. The cooling assembly of claim 1 , further comprising a coupling mechanism for coupling the intermediate portion to the mounting surface at the location of the opening.
7. The cooling assembly of claim 6 , wherein the coupling mechanism comprises a weld.
8. The cooling assembly of claim 7 , further comprising:
a first weld disposed between the first mounting end and the mounting surface; and
a second weld disposed between the second mounting end and the mounting surface.
9. The cooling assembly of claim 1 , further comprising a second body comprising a defined length and a cross-sectional shape having a thickness defined between an outer surface and an inner surface thereof, the second body including a first mounting end and a second mounting end;
wherein a third conduit is defined between the inner surface of the second body and the mounting surface, wherein the third conduit is aligned substantially parallel to the first and second conduits.
10. The cooling assembly of claim 9 , wherein the second mounting end of the body is coupled to the mounting surface adjacent to the first mounting end of the second body.
11. The cooling assembly of claim 10 , wherein a single weld couples the second mounting end of the body and the first mounting end of the second body to the mounting surface.
