Each sidewalltcontains'a certain-number of' vertical" heating' flues 2: and 2f which: com-i municatezthrough gas inlets Si' and 3 Withv four'` gas' 'chambers' 4 and r4( situated underneath, and'receivingfcokeoven gasthrough` pipesflO and-110 providedwithV diaphragme:-

G'ne half" of? thesidewallf receives the gas through: afpipe 10, fand the `otherhalf-receives it? througha pipe 10". The heatingflues 2' and 2 arel connected at their lovverpart? through connectionsfS'and 85 With theindi-` vidual regenerators 6 and- 6 situated belowy the ovens and-between Which-is placed a parr'-wr 100 401' to let the air arrive through the `flues 12into In each separation wall V13'and 13', thatV is for each half part of the sidewall, are placed two series of four air expansion chambers, one of the series being shown atrlll, and the other at 15. The four air eXpansion chambers of each series correspond with the four gaschamber's 4 or 4' of one or the otherof the -halves ofthe corresponding side-r wall; Each 'of the chambers 14 or 14 is connected on the one side througha conduit 16 or 16' with an air distributor 18 or 18', and on the other .side throughseveral header lues 25 or 25' with Jthe upper part 24 or 24' of the sidewalls. Each of the chambers 15 or 15' is connected on the one side through a conduit 17 or 17 with an vair distributor 19 or 19', and on the otherside through several header lues 23 or 23.'. with a. certain level 22 or 22 nof the heating iues. Each pair of distributors 18-19 and 18-19' is branched onv an .air delivery pipe 20 yor 20 in which the air is maintained at a certain pressure. Y

Let us suppose that the cocks 21 connect ing the gas delivery pipe 11 with the vgas chambers 4 Aare open, and that the cocks 21 connecting the gas pipe 11' with the gas chamber 4L' are closed. The reversing valve of the battery is placedin such a manner as the longitudinal regenerators 9, from which it is distributed into the various individual regenerators 6, and in such a manner as to evacuate the products of combustion through the iiues 12'. At the upper part ot each individual regenerator the hot air enters through the openings 8 into the heating flues 2 where it meet-s the gas rising from the gas chambers l through the openings 3.' TheV proportion of gas and the' first admission oi` air is so'chosen as to give an incomplete com bustion of the gas. The flame rises in each heating lue 2 and it meets at a certain level a secondary admission of air which'flows out through the opening 22. The two openings 22 of two adjacent iiues 2 are branched on av single header flue 23. the latter descending inthe wall 13 which acts as al 'separation wall between two distinct regenerators 6, and being connected at itslower part with on-e of the air expansion chambers 15 which is connected by a tube 17 to the distributor 19. The regulating member provided on each tube 17 makes it possible to adjust the amount of air admitted into the correspond part of the flue, and it enters into the horizontal collecting iiue 5, where it receives a third admission of air escaping through an opening 24. This opening 24 is the outlet 'of a header flue 25 which descends also in the separation wall 13 and which is connected also with one of the air expansion chambers 14, the lower part of which is connected by a tube 16 to the distributor 18. The regulating member provid-ed on each tube 16VV makes it possible to adjust the amountof air admitted tothe-corresponding airl expansion chamber ltvat will, and thus to adjust exactly the flow of the third admission of air for effecting a perfect combustion of the combustible elements arriving through each flue 2 into the horizontal collecting iiue 5.

The collecting flue 5 is connected withla collecting flue 5 which distributes the prod-Y ucts of combustion'into the heating ues 2' of the other yhalf of the sidewall. These products of combustion are collected inside the regenerator 6 of the corresponding oven,

where they give up the maj or portion of their heat. At the lower part of the various regenerators 6' the products of combustion are collected in the longitudinal regenerators 9' and evacuated 12. i

At the next reversion of the gaseous current, the reversing valve of the battery is placed in such a manner as to let the air arrive throughthe fiues 12 into the longi- -to the chimney through lues tudinal regenerators 9' from which it is distributed into the various individual regenerators 6' and in such a manner as to evacuate the products of combustion through the iues 12. The coclrs 21 connecting the gas pipe 11 with the gas chambers e will be closed and the coclrs 21 connecting the gas pipe 11 with the gas chambers 4 will be open. The admissions ofair from the pipe 2O to the distributors 18 and 19 will be closed, and those from the pipe 20" to the distributors 18 and 19' will be open. The heating of the right-hand side of the sidewall is effected in a manner similar to that indicated for the lett hand side of the sidewall.

The improvements described apply to ovens heated `with lean gas and to ovens heated simultaneously with rich and with lean gas.
