15 Claims.
This invention relates to heat transfer devices, and more particularly, to a support for a bank of tubes extendingacross a gas flue in such a device.
An object of the invention is to provide an intertube support and bracing members for a bank of tubes disposed across a fiue in a heat transfer device.
Another object of the invention is to provide in a bank of tubes of considerable length, intertube supports which coact with'the tubes in the bank to form a truss support therefor.
A specific object of the invention is to provide for a tube bank, characterized by a plurality of tubes extending across a gas flue in a plurality of return bends arranged in vertical rows, intertube supports between certain of the tubes to prevent buckling and sagging of the bank, while permitting expansion and contraction of the tubes, and supporting members at the ends of the bank to support the bank in its entirety.
Other objects will be apparent to those skilled in this particular art from the claims and the description in the specification in connection with the drawing, in which- Fig. l is a side view, in section, of a portion ofa boiler;
Fig. 2 is a sectional end view taken along the line 2-2 of Fig. 1;
Fig. 3 is an enlarged view of a structural detail of the invention.
In the embodiment of the invention chosen for purposes of illustration, in Fig. 1 is shown a boiler associated with a boiler setting, with the upper steam generating parts and steam and water drum, and a portion of the combustion chamber broken away. ,In this figure is shown a bank of steam generating tubes I connected at one end to downtake headers 2, and at the other end to a row of uptake headers 3.
A row of nipples t connects the downtake headers 2 with a second row of downtake headers 5 disposed therebelow. A mud drum 6 is connected by nipples 1 to the second row of downtake headers 5. A similar row of uptake headers 8 is connected by nipples 9 to the lower end of the row of uptake headers 3.
A bank of steam generating tubes H is connected at its ends to the headers 5 and 8, and a lower row of tubes l2, similarly connected to those headers, is disposed directly above a combustion chamber It and acts as a slag screen for the rest of the tubes. A superheater I5 is disposed in the space between the two banks of steam generating tubes l and II, and comprises a plurality of tubes arranged in vertical rows which extend across the gas flue IS in a plurality of return bends.
A supporting member 20 is secured at its upper end by a clamp 2| to the lowermost row .of the steam generating tube bank I, and at its lower end a bent portion 22 rests upon a baflle member 23 which is supported by the upper row of tubes of the bank II. The inlet and outlet ends of the superheater extend through the supporting member 20 and are connected respectively in an inlet header 25 and an outlet header 26 of the superheater. Members 21 and 28 are secured to the bent portions of the tubes at one end of the bank and extend through the support 20, where, in conjunction with the inlet and outlet ends they serve to support the superheater bank at that end.
Secured between adjacent tubes in the same vertical row is a plurality of metallic structural connectors 30 arranged between the tubes along a diagonal line through the bank to form, with. the metal of adjacent tubes, a truss support for the bank, which prevents bending in a vertical plane. Secured between the tubes of the upper and lower rows of the superheater bank laterally, are members 3|. These members act as cross ties and prevent buckling sideways.
The members 30 and 3| divide the tubes comprising the superheater bank into blocks, and by their bracing effect hold the tubes in each block in place with respect to each other and prevent substantial sagging or buckling distortion of the bank, while at the same time permitting expansion and contraction of the tubes.
The members 30 and 3| are exposed to the sweep of combustion gases at high temperature, but they are secured in good thermal contact to the tubes of the superheater l5 through which a heat absorbing medium is circulated so that they will not be heated to a destructively high temperature. At the same time these members do not present sufiicient cross sectional area to the gases to materially effect their flow.
Secured to the uptake nipples 9 in any desired manner, such as by bolting, are members which engage hook members 36, which are secured to the bent portions of the uppermost row of tubes of the superheater IS. The members 35 and 36 engage each other, and by their cooperation serve as a support for one end of the superheater bank. These members 35 and 36 may slide relative to each other so that contraction and expansion of the tubes is permitted. The other end of the bank is supported by the member 2| as previously described.
A specific supporting structure has been described in some. detail which is especially adapted to brace and support a long bank of tubes made up of a plurality of tubes arranged in vertical rows and extending across a gas flue in a plurality of return bends, but it is to be understood that such a combination of supporting and bracing members may have other uses, and although specific members have been described, it is to be understood that changes, omissions, substitutions and additions may be made within the spirit of the invention as defined by the appended claims.
