The invention herein is applicable not only to the burning of petroleum or coal tar oils in the Y Y y .3

flues but also to the burning of other liquid fuels such as fluid coal tar or petroleum tar, etc. and the term liquid hydrocarbon material is used herein to include all such liquid fuels. Y

The invention as hereinabove set forth is embodied in a particular form of construction but may be variously embodied Within the scope of the following claim.k

I claim: Y

The method of Yoperating a regenerative coke oven battery, comprising alternate, horizontally elongated, coking chambers and heating Walls arranged side by side, the heating walls being composed of horizontal, Zig-zag, series-connected, combustion fiues, which. involves generating the heat necessary to coke the charge of cokable material in the coking chambers by simultaneously introducing into the ends of said flues air and oil from the group: coal tar oil and petroleum oil, thus atomizing and dispersingr the oil forming a mist Vextending throughout the length of said flues, and simultaneously passing preheated air from the regenerators through said flues to support the combustion of said oil mist in said ues, which combustion takes place in long flames throughout the length of said flues.
