Int. Cl. B61d 3/16; Cb 39/14 US. Cl. 202-262 1 Claim ABSTRACT OF THE DISCLOSURE A coke quenching car is provided with a plurality of transversely extending bafiles that reduce the gap between the quenching car and the coke guide hood. The end walls and one side of the car, like the bafiles extend above the top of the quenching car locomotive.

CROSS REFERENCE TO RELATED APPLICATION This is a division of application Ser. No. 212,570, filed Dec. 27, 1971, and now US. Pat. No. 3,788,236.

BRIEF SUMMARY OF THE INVENTION A conventional coke quenching car is provided with a raised longitudinal side; particularly the side opposite the coke oven battery. The interior of the quenching car is subdivided by spaced apart internal bafiie plate extending transversely of the car. The end walls of the car are also extended vertically.

For a further understanding of the invention and for features and advantages thereof, reference may be made to the following description and the drawing which illustrates a preferred embodiment of equipment in accordance with the invention which is suitable for practicing the method of the invention.

BRIEF DESCRIPTION OF THE DRAWINGS In the drawings:

FIG. 1 is a schematic elevational view of a coke quenching car of the invention and a locomotive for moving such car;

FIG. 1a is a schematic side elevation view of an improved coke quenching car in accordance with the invention;

FIG. 2 is a schematic plan view of the locomotive and car of FIG. 1;

FIG. 2a is a plan view of the car of FIG. 1 without the hood shown therein;

FIG. 3 is an end view of the car of FIG. 1; and

FIG. 4 is a sectional view along line IVIV of FIGS. 1a and 2a.

DETAILED DESCRIPTION Referring to FIG. 1a, a conventional coke quenching car 11 is indicated in phantom outline. To the car 11 there has been added a longitudinally extending side plate 13, two upwardly extending end walls 15, 17, and three spaced apart transversely extending interior baflie plates 19, 21, 23.

Each interior baflle plate 19, 21, 23 is bolted or otherwise suitably connected to the side wall and to the bottom of the coke quenching car 11, and is provided with a pair of conventional turnbuckles 25. The turnbuckles 25 connect to the bafile plates 19, 21, 23 at one end, and to the upwardly extending side plate 13 at the other end. These turnbuckles 25 are adjustable so as to keep and maintain the baffle plates 19, 21, 23 about perpendicular to the longitudinal side walls of the coke quenching car 11.

It will be noted from FIGS. 3 and 4, that the upwardly extending end walls 15, 17 and the interior transversely extending batfles 19, 21, 23 do not extend transversely across the full width of the coke quenching car 11, since it has been found that this is not necessary.

FIG. 1a also shows in outline form a coke guide fume hood 27 like that described in copending application, Ser. No. 170,926 filed Aug. 11, 1971, and now US. Pat. No. 3,785,933. The hood 27 is shown in the drawing in an aligned position at a coke oven chamber 29 from which coke 31 is being pushed, and coke already fills one interior space in the quenching car, as at 33. The hood 27 has a pair of horizontally extending covers 35, 37 which are about as extensive lengthwise as the distance between adjacent baffies 19, 21 or 21, 23, or between a baflle and an end wall.

Investigation has shown that the eflicacy of a hood for collecting smoke, dust and fumes from coke as it is being pushed from a coke oven chamber depends upon the control exercised to limit the amount of air that contacts the incandescent coke. Earlier forms of hoods, that are disclosed in the prior art and that are used in the industry, had a wide gap between the quenching car and the hood, which gap was required to permit the unobstructed passage of the quenching car locomotive under the hood. This wide gap admitted much air and cross winds that greatly aifected the control of the emission of smoke, dust and fumes.

From FIG. 1a it will be noted that the coke 33 has already filled the space in the quenching car between baffle 23 and end wall 17 and that, as the coke quenching car moves in the direction of the arrow A, the resident coke 33 is covered by the cover 37. The falling coke 31 is filling the next adjacent space in the quenching car between the baffles 21, 23 and the cover 35 covers the space between the bafiles 19, 21.

The coke guide hood 27 and the covers 35, 37 are spaced apart about two inches above the top edge of the bafiles and the same distance above the end walls while coke is bein pushed. The covers 35, 37, as described in the aforementioned copending application, may be raised when coke pushing has ended, and may be lowered just before and maintained during the coke pushing period. Therefore, there is very little open area for air and cross winds to contact the hot coke and to cause great amounts of smoke, dust and fumes to be emitted.

From the foregoing description of one embodiment of the invention, those skilled in the art should recognize many important features and advantages of it, among which the following is particularly significant:

That, because reasonably well heated coke emits dust and fumes during its movement through the coke guide, during its fall into the quenching car, and for a few seconds thereafter while resident in the quenching car, little or no undesirable emissions occur since the covers and internal baflies effectively isolate the falling coke and any fumes and dust that do evolve are carried away in the hood.

Although the invention has been described herein with a certain degree of particularity it is understood that the present disclosure has been made only as an example and that the scope of the invention is defined by what is hereinafter claimed.

What is claimed is:

1. In a system for guiding coke through a coke guide and a quenching car that is adapted for movement by a locomotive for receiving the coke, the improvement comprising:

(a) a plurality of cantilevered bafiles installed to one side of and within and extending transversely of said quenching car, with the top edge of said baflies being above the top of said locomotive, said bafiles dividing said quenching car into a plurality of coke carrying 3 spaces and being spaced apart from the bottom and from the other side of said car;

(b) means connected to said one of the sides and to each baffle supporting it in a transverse position in said car; and

(c) a cover on said coke guide that extends over at least two of said coke carrying spaces as coke is being received in said quenching car.
