rUnNAcE-SETTING ron THE DESTRUCTIVE DIQSTILL'ATION OF OAL 0R OTHER cAms'oNAcEoU's sUBs'rANGEs.

To all whom z't may concern.

Be it known that I, STEPHEN a subject of the King of Grdeat Britain and ireland, rcsidin Lane; London, E. C., Eng and, have invented certain lnew and useful Improvements Relating to IIurnace-Settings for' the I Destructive Distillation of Coal or other Carbonaceous Substances, of which the followigis'a specification. .y i U This invention relates to furnace' settings for the destructive'distillation ot'V coal or other carbonaceous substances and especially 'to that type of furnace at the top and of an oblong wardly toward the bottom are set 1 n a known' settings where vertical retorts are employed which are charged discharged at the bottom, and where the retorts areA of an oblong section; and thev inventio'n has for its object to effect the heating of 'the retorts uniformly and with eiciency and in such manner that the temperature conditions throughou precisely regulated according' to" acter f the residue and by-products re- The respective retorts Whi'clilaie formed cross section and ytap'ered outmanner between series of horizontal parti- .,-to traverse the lengt chamber lto and fro so charged.

ltions which 4form a vertical series of horizontal chambers besideand between the re spectiveretorts and extend from one wall of the setting to the other. These chambers are provided according to the invention with two thin vertically disposed partitions by `which a central combustion spaccis formed between themby which the heating gases are compelled to take a tortuous nath, that is h of thehorizgntal thatV thus the heating space besidey the". retorty before being dis-` Two' such thin are provided in eachV horizontal chamber so th'atthusa mixture of gasani air'inay pass between the respective two partitions of eachzset and on reaching the end'of the partitions opposite to that-at which the mixture of gas and air is admittedj, the gases may y return and pass on the outer side of each of the .partitions along' the lateral spaces be tween the respective partitions and the adj acent retorts. The heatingr gases are thus di- 'rected in contact with theouter surface of Newcomer at 39 Mincing f may be he charvertical partitions Vspective vertical 4 Av peoioation of Letters Tatent.

the retort and the circulation of the gasesV takes place withinr one plane.

According to the invention moreover, I provide adjacent the series-of retorts, a. series of substantially vertical exhaust iiues correspondingin number to the number ofA horizontal chambers of the respective vertical series.

.A recuperator or regenerator is provided `advantageously beneath the setting and pas sages are fprmed or a chamber is provided 1n the setting through which the'air may pass before entering'the respective vertical 1r iiues, the construction of thechamber or passages being such that the walls Vthereof areheated by the exhaustgases passing out: orli'nstead a regencrator may beprovided 1 n which the fiow of air and the exhaust gases maybe reversed-in the regenerator.

understood that the waste gases will always pass through the vertical series of exhaust dues and the air through the vertical series furnace setting taken on the line F of Flg. 2,

Fig. 2 is a vertical section on the line A, of Fig. 1, r

Flg. 3 is a compound vertical section on Vthe line C, D of Fig. 1, and

Fig. 4; is a vertical section on the line Gr, H of Fig. 1.

` In carrying the invention into .reect according to ione construction vI provide a series of vertical retorts a of oblong section within a setting in the lower part of which a regenerator or recuperator b1 is provided,

I provdebeside and between the reretorts a vertical series of horizontal partitions b without necessarily .In such a modification, however, it will be L which form a central combustion space comparatively Wideextending the length of the retort into which at one end the supply of 'gas and air passes for combustion therein.

The vertical partitions, however, extend at the other end of the heating chamber opposite to that at which the gas and air enter a little short of the extreme end wall so that thus a space is formed at that end 4into which the gases may discharge and return in the opposite direction through the nar-V rower lateral spaces c1 formed by the partitions on each sideof the central space.

' A damper block c2 be provided at the end of the heating chamber at which the gases discharge from the central vcombustion s ace. Such damper blocks present their lnclined faces to the current of gases so that thus the inclined faces serve to deiiect the gases while the damper block serves at the same time to regulate the outflow according to the position in which it is pf z d with respect to the ends o f the partitior c.

The respective vertical partitions c referred to are provided of the same refractory material as that of which the horizontal partitions b are provided or they may be formed asa tube of a square or other suitable section so as to divide the heating chamber by substantially vertical walls into three spaces on`each side of the retorts.

The gas may be led into the central combustion space throu h a horizontal pipe d extending through t e setting at one side,

lthe gas pipe for each chamber of the vertical series being connected to a substantially' Y vertical service pipe d* mounted on the exterior wall of the setting. An' air passage e is also provided horizontall in the setting for leadingV air to each o the combustion spaces, and the air passage foreach heating chamber of the vertical series communicates with the respective vertical air eouslj7 may be led 1r fiues f from each side into the respective yhorizontal air passages e, and the ports g through which the air is admitted to the respective horizontal passages may be regulated by means of sliding dampers g1 or other suitable means.'

As Ithe greater thickness of the charge of coa'lin'the'lower ends of the tapered retorts necessitates rthe expenditure of more heat in dist'ill'atio'n'- than at the upper and thinner portion .of the charge, the gas pipes d of the rovided of lower -h eatin chambers are reater capaclty than those o the upper eating chambers. p

outer Wall ofthe casing of angular form may` the sald horizontal Thel horizontal air passages e may be formed as tubes of metal or' the may be formed of refractory material, while the-corresponding gas pipe for each air passage may pass centrally therethrough and the horizontal air passage may extend to the hmay be mounted. v

A series of vertical exhaust lines i is built in the setting adjacent the heating cham: bers, and ports j are provided in the intermediate wall through .which the gases may discharge from the lateral spaces 'of the lheatin chambers Ainto the adjacent exhaust iue.` twill be understood that in such an arrangement the series of vertical air ues therespective exhaust and air fluesare arranged in line.

With respect to other constructional features the construction and arrangement of the furnace setting is substantially the same as that described in the specification filed pursuant to the prior application No.'53,631 of 1915.

I claim:-

1. In a furnace settin for vertical retorts for the destructive istillation of coal and other carbonaceous substances, vertical retorts of an .oblon section in horizontal plan, a series of horlzontal artitions in the setting adjacent the sides ofp a series of separate heatinglchambers Qn eac side of the respective retorts, and two verwhere a valve plate14 1s arranged adjacent to the exhaust iiues and the said-retorts, the said horizontal partitionsthus forming' tical partitions in the respective Aheating chambers thus formed, reach' vfrom one end of the re ective heating c ambers to a point short -o which a tortuous path is presented for the heating gases, substantially as described.
