' In the vertical regenerative chamber ovens the heating walls of which are subdivided so as to form a plurality of verticalheating flues, these heating walls generally are sup- 5 plied with the flamesfrom bottom to top during one period and from top to bottom during the subsequent period. Ifcoke ovens of this type are to be heated by different kinds of gas, or if coals of difierent proper- V ties are tobe distilled or coked therein, difliculties arise frequently as to the heating oi the heating walls, as it is desirable according to the nature of the heating gas-or of the coal to be heated, to heat more strongly either I the upper or lowerportion of the heating walls. With continuously operating ovens the mentioned heating method further suffers from the drawback that the oven,when' heated from top to bottom, becomes too hot in its upper portion, whereby the fed coalis heated too quickly and has the tendency'of hanging in the upper portion of the cham- 'b'er.

Now the invention hereinafter described: oiiers in a-verysimple manner the possibility of obtaining on the one hand the proper main combustion, that means the union of heating gas and air,'within the vertical heat-- ing flues at a certain distance remote from aothe flue ends, and, 0n-the0ther hand, caus-' ing-a combustion to take place in the horizontal heating channels, the extent of whichcombustion may be regulated as desired.

In order to allow of my invention to be more easily understood,'a preferred embodiment of the same is illustrated byway'ofe xample in the drawing which accompanies and forms part ofrthis specification. In this drawing:

is a vertical longitudinal section through the oven battery, Y 7 V I Fig. 2 is-avertical section on line 2-2 of Fig. 1,. and

" Fig. 3'is a horizontal section on line 8+3 the-vertical oven chambers whichhave arranged between them the heating walls 6 sub-;

horizontally overthe whole length of the heating wall. "They have upper and lower passages e and f opening into the heating flues providing admission ports between the horizontal channels and the vertical flues. In

order to cause a certain advance combustion to take place in the channels 0 and d, prior to. the main comhustionin the vertical fiues, dainper bricks it, see Figs. 2 and 3, are arranged in the partitions g separating every pair of channels 0 and d. As Fig; 2shows, these damper bricks'hare superimposed crosswise, and their mutual position may be adjusted from perforations 71 provided in the cover of the oven masonry; According to the amountiof the angle'at which the bricks 7L are'adjusted relatively to the partition g, a greateror less passage of'heating gas .and

air may take place into the companion (than.-

nels 0 and d, whereby the desired combustion in these channels is obtained. With heating gases which give but a comparatively short flame when mixed with the combustion air, it may further be desirable, to distribute the union of gas and air over a greater space within the heating flues. To this end partitions 70, see particularly Figs. land '2, are

built in the heating fiues which partitions project into the fines to a certain extent from above and below. These partitions 76 may further be provided with holes 10 inorder to'alsofhave a certain combustion atthe top and bottom ends of the heating flues brought. about by the mutual transition of gas and air through, the holes 70 With ovens ofa type 1n which heating "walls are flamed always in one direction, the

damper bricks h and partitions 7c "are ..arranged only 1 in those ends of the heating fines where the supply of the agents of combustion takes place. e I

My invention is further particularly adaptedto. be employed in continuously operating ones-1 vertical chamber ovens, as with a suitable adjustment of the damper bricks h and suit able arrangement of the upper partitions 7c the main combustion begins only a certain distance below the top end of the heating fiues and care is taken, on the other hand, to provide-the temperature required to preheat :the coal in the upper chamber portions by the described partial combustion,,prior to the main combustionin the vertical fines.

My invention thus enables differentdesired high temperature to be obtained in the different levels of the heating walls, as this'was the casehithertoonly with vertical chamber ovenshaving horizontal fiues. At thesame time the known advantages are obtained which result from the provision of vertical heating fiues in comparison with horizontal What I claim and desire to secure by Letters Patent, is: r

In a coke oven havingxa coking chamber, a heating wall 3 with vertical heating =fiues' for said chamber, a horizontal combustion channel forming part of the-heating Wall and communicably connected to the vertical heating fines, means'for conducting gas andyair separately and simultaneously to 1 said channel and means for ad usting the amountvo'f gas and air suppliediso as to en: able an adjustable combustion. to take place in said channel. 7 a
