E. COPPEE com oven med la 26, 1927 INVEN''OR;
Patented Sept. 9, 1930 UNITED STATES EVENCE COPI'EE, OF BBUSSELS, BELGIUM CORE -OVEN Application filed lay 28, 1927, Serial No. 194303, and in Belgium September 4, 1926.
The present invention relates to improvementsin or modification of the oven described in my copendin patent application filed the 15th June 1926 erial No. 116,085.
According to this copending application, the wall of the coke oven comprises an even number of groups of vertical flues each of which is connected to the one adjacent to it by a communication chamber, these chambers being' disposed alternately near the top and near the bottom alon the length of the wall.
F urther, the whole o the fluid burning agent is admitted at the base of the first group with a fraction only of the total amount of gas serving for the combustion, called primary gases, while the balance of the gas i. e., the secondary gas is admitted along the path of the burning current.
In the oven described, in my co ending application Serial No. 116,085 the a mission o secondary gas takes place only in the upper communication chambers between one group to the next near the partitions separating these groups.
Now, the groups of descending flues which are located beyond the points at which these admissions of secondary gas are made absorb approximately 90 to 95% of the heat of the flame absorbed by a descending group and the ascending group which follows it. As a consequence the efliciency of these last groups is practically zero.
In order to remove these disadvantages, the present invention provides, in addition to the admissions of secondary gas into the upper communication chambers of the walls, for admissions of secondary gas into the lower communication chambers.
In the accompanying drawing, the figure is a longitudinal section throu h a part of a coke oven wall according to t e invention.
It shows, that the wall is formed by a series of an even number of groups of vertical combustion flues 3. These groups, which are separated from each other by partition walls 1, are connected together b communication chambers 2 placed' alternatvelyat their upper and lower ends over the whole length of the wall.
By adopting the stage of regeneraton for which the current circulates from left to right, in the wall considered, it is seen that the hot air coming from a regenerator 4 is distributed by ducts 5 arranged at the base of the uptake flues of the left end group according to the draught which is regulated by means of dampers 14 located at the upper part of the flues. A part of the gases serving for the combustion, called primar gas, is drawn through a pipe 6 into a distri uting duct 7 and is distributed in the same flues 3 by means of calibrated and removable pipes 9 to which access may be had through ins ection holes 10 formed in the roof of the wall The mixture of burning air and gas thus formed rises in the first group of flues 3 and changes direction as it passes from each subsequent group so that a flow as through baffles is obtained.
Dampers 15 similar to the dampers 14 enable the e ual distribution of the gaseous current in t e vertical flues forming 'the consecutive'groups to be obtained.
What I claim is:
In a coke oven, a coking chamber, a heating wall for said chamber, comprising a series of an even number of at least four grou s of vertical combustion flues, said groups eing communicatively connected together in series by horizontal bus flues above, and at leastone horizontal bus flue below, said vertical combustion flues, means for admitting air into and discharging burnt gas alternately from each of the outer groups, means for admitting fuel gas into each of the outer groups, and means for admitting fuel gas directly into each of the horizontal bus flues.
In testimony whereof I aflix my signature.
EVENCE COPPE.
