PATENT OFFICE CARL OTTO, OF HELLERUP, DENMARK conn OVEN Application led March 20, 1925. Serial No. 17,101.

My invention relates to a burner-Hue construction for coke ovens with horizontal or vertical oven chambers, and particularly to such a burner-Hue which will produce a uni- 5 form heating in a` vertical direction of the Hue when the oven is heated with strong gas.

One of the objectsof the invention is to avoid eddies which might otherwise occur between the gas and air supplied and thus to avoid a quick combustion and an overheating of the lower part of the oven chamber as well as to avoid eddying of the gas toward the walls of the heating Hue which would cause a deposit of carbon upon the Hue and an overheating of this portion of the Hue wall. The carbon deposit burns with difHculty and such burning can be accomplished only by supplying a large amount of excess air, which, however, leads to a shortening of the `flame and an overheating of the lower part of the oven dhamber.

In accordance with the invention, the burner opening is' raised to such a height in the Hue and the air is supplied at the bottom of the Hue at some distance below the burner opening in such a way that the air supply is slowed up and the air has time to rise in the space in the Hue between the burner and the Hue walls, so as to produce auniform, eddy-free, upward flow and thereupon to uniformly supply the gas escaping from the burner. In the best embodiment of the invention, the gas burnci` is tapered toward its burner end to avoid eddies and to guide the air to the burner.

With the above and other objects in View, my invention consists in the parts, improvements and combinations more fully pointed out hereinafter.

Referring now to the drawings:

Figure 1, is a vertical cross-section of a porv tion of a horizontal coke oven, showing my improved burner-Hue construction.

Figure'Q, is a vertical cross-section taken at right-angles to Figure 1.

Figure 3, is a detailed cross-sectional view thru the burner-Hue construction, on the line 3 3 of Figure 1, and,

Figure 4, is a horizontal-cross-section on l line 4 4 of Figure 3.

The horizontal coke oven is provided with horizontal coking chambers 1, at each side of which heating Hues 2, are arranged. Regenerators 3, preheat the air, or one regenerator may be used to preheat air and another regenerator may preheat weak gas, if.

desired.

The oven is shown as provided with supports 4, thus forming an underburner oven. Strong gas is supplied to the burners 5, thru Vertical pipes 6, which, in turn, communicate with horizontal gas supply pipes 7 supplied by gas main 8, arranged in the underburner part of the oven.

In accordance with the invention, the burner top 9, is arranged within and above the bottom of the Hues 2. As shown, the Hues are of the same length. The burner in the heating Hue'is kept within heating proximity of and projects above the bottom of the coking chamber. Preheated air coming from the regenerators 3, passes into the bottom of the Hue thru passageways 10, 11, arranged on each side of the burner. and passes upwardly in uniformly Howing streams on each side oi the burner. When desired, air may be supplied to the heating zone thru one passageway 10` and weak gas thru the other passageway 11, supplied from its respective regenerator, the strong gas burner 5, being then not used. The burner is separated from the side of the Hue Walls, thus forming a space between the burner and the walls to which the air :tor the burner is supplied.

wWhen burning with strong gas thru burner 5, the air supplied from both passageways will be free from eddies when it reaches the top 9 ot the burner 5, by reason of the long travel of the air before it reaches the burner top. Inclined guiding walls 12, 13, are pro-, vided at the discharge end of the air passageways 10 and 11, so as to guide the air upwardly. The strong gas burner 5, is made tapering at 14, toward its top so as to guide the air to the burner top 9, Without causing eddies. The upper portion of the strong gas burn er 5, may be made removable by providing a joint 15, between the upper portion of he burner' and its base. This upper portion may then be removed by inserting a rod into Hue holes 16. i

As shown in Figures l and 2, the strong ga burners may be alternately high and low burners which extend to diierent heights from and above the bottoms of the various Hues, and may be in successive Hues, so as to provide a uniform heating for the lower part of the oven chamber.

Having thus described the invention and its operation, it will be understood that changes ma be made in carrying the invention into e ect, without departing from the principle thereof. j

What I claim and desire to secure by Letters Patent is:

1. In a coke oven heating wall having a plurality of vertical combustion flues, each of the same length, the bottoms of the Hues being on substantially the same level, the combination with said Huves of a plurality of fuel gas burners the said burners extending to different heights above the bottoms of the Hues each burner projecting into its Hue above the Hue bottom, and means forsupplying air to each of said Hues, below its burner.

2. In a coke oven heating wall having a plurality of vertical combustion lues in a row, each of the same length, the bottoms of the Hues being on substantially the same level, the combination with said Hues. of a plurality of alternate high and low strong gas burners said burners extending to different heights above the bottoms of successive Hues and projectinginto said Hues from and above the bottoms thereof, and means for supplying air at the bottom of each of said Hues.

3. In a coke oven heating wall having `a plurality of vertical combustion Hues, each of the same length, the bottoms of the Hues being on substantially the same level, the combination with said Hues, ot' a plurality of strong gasv burners eXtending to different heights in said Hues, said burners being tapered at their sides toward their tops and projecting into said Hues from and above the bottoms thereof, and means for supplying air at the bottom of each ot said Hues.

4. In a coke oven heating wall having a plurality of vertical combustion fines, each of the same length, the bottoms of the Hues being on substantially the same level, the combination with said Hues of a plurality ot' strong gas burners extending to diilierent heights in said Hues and projecting into the said Hues from and above the bottoms thereof, and means for separately supplying weak gas and air at the bottom of each of said flues.
