Beit l'tnownthat I, @aan STiLL, a subject of the German' Emperor, residing afi Rienk-v linghausen', Westphalia, in the German E1npire, have invent-ed certain new' and useful Improvements in Horizontalv Celrevens, of which the following' is aI specification.

This invention relates to horizontal coke ovens lia vings. vertical heating: iues to which the heating gas is supplied through channels ormed within the underlying `refractory masonry, and it is the object of the invention to providemeans whereby the disadvantages and disturbances commonly connected .with such a system vfor supplying gas to the heating fines are avoided and a continuous and uniform distribution of the gas to all part-s where combustion occurs is guaranteed.

It is common practice to conduct the heating gases, to theyertical heating flues of such horizontal coke ovens throughnozzles arranged one at the foot of each heating fiue 'and having orifices of small cross section; this cross section has to bel carefully'detei-mined in order that the distribution oit the gas and consequently'the heating of all the ues may be uniform. Owing to the high temperature prevailing in the` whole masonry atthe bottom of the heating iiues the gas passing through the nozzle becomes heated to such a temperature that it is ,partially decomposed and carbon is liable to be deposited within the nozzle, thus clicking it and preventing the passage ofthe correct amount of gas for the .proper heating of the iiue. Another cause of such obstructioi' is the peeling oii of particles of the material of which the heating fiue is constructed, which particles either cover `or enter the orifices of the nozzles and choke them. This -difiiculty arises from the narrow cross section of the orifice which, however, must beLv maintained .for the reason aforesaid.

The present inventionminimizes lthe liability of disturbances due to the small cross section of the orifices of the nozzles by' pro-` viding each heating tlue with two nozzles, one vertically above the other, the lower being the nozzle for the distribution of the gas and the upper a combustion nozzle adapted to protect thel'ower nozzle. The lower distributing nozzle has the necessary narrow cross section aforesaid, but it is situated at such a. distance below the'upper coni bustion nozzle that its temperature is coini en emerse ear C RL STILL, 0F RCKL'INGHAUSEN, GERMANY.,

giaratively low and ,decomposition off' thev h eaiaug'- gases passing through itv is not hable to occur. The' vupper nozzle' is situated? att-lievbcttoin ofthe heating iue but nas-an orifice of greater cross sectional area than that of; tli'ef'orifiee of? the lower' nozzleso thut the correct' volume-of heating gases .can pass even should the nozzle become par- ;tially obstructed-y :tromR either. ofthe"l causes aforesaid.

pT-he lower distributing nozzles a have passages of the correct cross lsection for def termlning the proper distribution of the heating gases in the heating fines, while the upper nozzles have passages of larger cross sectional area,and are situated one at the bottom of each heating flue which is the customary position. As will be seen the lower nozzle is at a considerable distance below the upper one. The arrow at the bottom of Fig. 2 indicates the passage of the gas from the distributing channel through the nozzle a. They arrows shown in the upl per part of F ig. 2 indicate the'passagepf g5 air for burningthe heating gas in the flue.

Having thus described mfvinvention and.` the best means I know of carrying the same claim ztion comprising vertical' heating lues, channels formed completely within and by the. l

underlying masonry and adaptedv to supply heating gas to the said tlues, a gas nozzle of fixed orifice at the lower/part of each fiue, I

'passages for admission of air for combustion 'into each flue above. this vrnozzle, a second gas nozzle also of fixeld orifice below the first gas nozzle, the orifice of .the said second gas nozzle being of smaller cross section 1o( than the orifice of the first named gas. nozzle.

In testimony whereof I have affixed my signature in presence of two witnesses.
