Description
United States Patent TUYERE COOLER Joseph Yuhas, North Braddock, Pa., and John V. Makar,
deceased, late of Swissvale, Pa., by Mary F. Makar, administratrix, Swissvale, Pa., assignors to United States Steel Corporation, a corporation of New Jersey Application August 9, 1954, Serial No. 448,634
1 Claim. (Cl. 266-41) extended longitudinally from the inlet opening along the greater part of the length of the cooling chamber to form a passageway for conveying the water to the outer end wall of the cooler. With this design, circulation of the water in the cooling chamber was retarded to the extent that silt and sediment contained in the water settled in the cooling chamber with the result that the lower part of the chamber became clogged causing the equipment to fail prematurely.
We propose to eliminate such clogging by providing a tuyere cooler having a bafile in its cooling chamber which induces circulation of the cooling medium throughout the chamber.
It is, accordingly, an object of our invention to provide a tuyere cooler having a baifie extending a short distance inwardly from the inlet opening and then downwardly across and spaced from the inlet opening partially around the circumference of the cooling chamber whereby the cooling fluid passing through the inlet opening is caused to circulate around the circumference of the cooling chamber.
This and other objects will become more apparent after referring to the following specification and attached drawing, in which:
Figure l is a vertical sectional view;
Figure 2 is a perspective view, partly in section; and
Figure 3 is an end view, partly in section, looking toward the left end of Figure 2.
Referring more particularly to the drawing, reference numeral 2 designates the body of our tuyere cooler which may be a copper casting, frusto conical in shape and having a longitudinal passage 4 therethrough. The tuyere cooler of our invention is shown installed in the conventional manner in the wall 6 of a blast furnace 8 for cooling a tuyere 10.
The body 2 of the tuyere cooler includes a front face 12 and a rear face 14 into which tuyere is fitted. Spaced inlet and outlet openings 16 and 18, respectively, are provided in the upper portion of the front face 12 communicating with a cooling chamber 19 defined by spaced inner and outer walls 20 and 22 of the body 2.
ice
A passageway for the incoming cooling medium is provided by casting or otherwise fitting a bafiie 24 adjacent to the inlet opening 16. The baflie 24 includes a first 26 extending from the inner surface of the front face 12 longitudinally a short distance into the cooling chamber 19 where the baflie is bent at an angle of approximately degrees to form a second continuous section 28 which extends circumferentially part way around the periphery of the chamber 19.
In operation, water is introduced into the cooling chamber 19 via the inlet opening 16 through a supply line, not shown, connected thereto. The cooling water entering through the inlet opening 1% passes through the passageway formed by the baflle 24 and is thereby given a positive helical motion so that settlement of silt and sediment from the water is prevented. Any substances in the water which would cause sediment are carried in solution and pass out of the outlet opening 18 with the water. Thus, the heat absorbed by the tuyere cooler of our invention is dissipated more uniformly and efficiently than was possible heretofore.
While one embodiment of our invention has been shown and described, it will be apparent that other adaptations and modifications may be made without departing from the scope of the following claim.
We claim:
A tuyere cooler comprising a hollow frusto-conical body with a smaller diameter end and a greater diameter end and having a centrally disposed longitudinal passageway therethrough, a rear face on the smaller diameter end of said body radially surrounding one end of said passageway, a front face on the greater diameter end of said body radially surrounding the other end of said passageway, said body having spaced curved inner and outer walls extending between and connecting said faces and defining a cooling chamber surrounding said passageway substantially along its length, said front face having an inlet opening and an outlet opening there through disposed in spaced relation and communicating with said cooling chamber, and a baffie in said cooling chamber, said baffle including a first section extending a relatively short distance inwardly from said front face longitudinally of said cooling chamber and a second continuous section extending angularly at about 90 degrees from said first section partially around the circumference of said chamber, said inlet opening being disposed in the portion of said front face spaced opposite from and extending parallel with said second section whereby cool ing fluid passing through said inlet is caused to follow a substantially circulatory path in said cooling chamber.
