Jan. 6, 1942. w. UNDER REGENERATIVE GAs HEATER Filed Apri Patented Jan. 6, 1942 UNITEDQSTATES Pm"ENTl OFFICE` Willy Linder, Essen, Germany, assignor, by mesne assignments, to Kappers Company, Pittsburgh, Pa., a corporation of Delaware Application April 5, 1940, Serial No. 327,952

- In Germany April 14, 1939 6 Claims.

In Letters Patent of Joseph Daniels for irnprovements in regenerative heaters and the like, No. 2,141,036, a new type of regenerative heaters for gases or vapours,` e. g. for gases serving as heat carriers for continually operated water gas producers or for carrying out other gas reactions at high temperatures, is disclosed. That heater is provided with a separate combustion shaft arranged outside the casing for the chequerwork and extending from the dome thereof. In this combustion shaft the combustion of the media serving for the heating of the chequerwork takes place. The burner arranged at the bottom of the shaft according to the above mentioned patent comprises a series of parallel walls extending over the whole cross section of the shaft. Gas and air are introduced separately into alternate spaces between said walls so that a complete combustion is effected over the whole area of the shaft and combustion gases of very high temperature are produced which have no tendency to give what I call surface combustion when touching the chequerwork.

Now, the object of my present invention is to provide further improvements in the burner system of the gas heater and its combustion shaft respectively.

My invention principally consists in providing nozzles for introducing the fuel-gas, which are distributed over the whole circumference of the shaft, said nozzles being arranged-radially or tangentially to the shaft aXis just above the upper side of arch-like diametrical partition walls which .are provided with suitable gas distributing channels which open into further nozzles arranged at the upper side of said partition walls, and the combustion air is introduced into the shaft from the space beneath said arch-like partition walls through the intermediate spaces therebetween.

The burner system according to the present invention is of special advantage with regard to regenerative heaters provided with a combustion shaft of great diameter. My invention ensures a complete and uniform combustion of the fuel gas and air within the combustion shaft of the heater in that the media are perfectly distributed over the whole area notwithstanding its diameter.

With the above and other objects and features of my present invention in view, I shall now describe a preferred embodiment thereof on the line of the accompanying drawing, in which:

Fig. 1 is a vertical 'section taken longitudinally through the ,burning system arranged vat the bottom of the combustion shaft.

Fig. 2 a horizontal cross section von line II-II of Fig. 1.

For simplicitys sake Athe heater casing comprising the chequerwork andthe connection between the` chequerwork casing and combustion shaft is not shown on the drawing since these parts of the heater may be designed in any suitable manner.

The combustion shaft,4 part of which is shown in the drawing comprises substantially a Vertical preferably cylindrical chamber I. The walls 2 of the combustion shaft I are made of suitable refractory brickwork which is enclosed by a casing 3 consisting of sheet plate or the like. Near the bottom 4 of the shaft, openings 5 are arranged in the side walls of the shaft for introducing air under pressure. openings 5 a series of radially or tangentially arranged gas nozzles 6, 'I is provided, preferably in two rows one above the other. The nozzles t of the upper row alternate with the nozzles 1 of the lower row, so that a circle of closely adjacent nozzles results.

Below the gas nozzles 6, 'I arched partitions 8 are arranged in the shaft I, said partitions being provided with gas distributing channels 9. The partitions meet in the centre of the shaft. Gas nozzles Il] are disposed on the upper side of the partitions 8 and the gas channels 9 are connected to the nozzles I8, arranged preferably at uniform distances from the shaft centre.

The gas channels 9 are connected outside the shaft casing with gas pipes II controlled by regulable valves I2 and shut-olf valves I3. These valves I2, I3 are accessible from a service platform I4. The shut-off valves I3 are actuated by a common mechanism, as by means of a ringlike controller I5 slidably mounted on. rolls I6 which are arranged in bearings I'I, said bearings II being attached to the platform I4. A

hydraulically or pneumatically operated piston off from the heater downwardly through the shaft I and are taken off from the shaft I through suitable upper gas oiftake openings arq Above the 'air ranged in the side Wall of shaft I above the gas nozzles 6, 1, or through the bottom openings 5.

I have now above described my present invention on the lines of a preferred embodiment thereof, but my invention is not limited in all its aspects to the mode of carrying it out as described and shown, since the invention may bev variously embodied within Vthe scope of the following claims.

I claim:

1. A combustion shaft comprising nozzle-like openings in the Walls of the combustion Vshaft for introducing fuel gas thereinto, arch-like vertical partition walls arranged; within the said combustion shaft below said wall openings, fur-l' ther fuel gas inlets for the upper side of said partition walls, air inlets arranged in'the Wall of the combustion shaft beneath said partition Walls in such a manner, that air introduced through such openings may pass through the intermediate spaces between .the partition. Walls up into the upper part ofthe combustion shaft.

2. A combustion shaft comprising: an annular series of arch-like diametrically .extending partition walls spanning theshaft and meeting atlltheaxis thereof nozzles for introducing fuel gas for combustion distributed around the .shaft and extending through the shaft Wall just above the upper surfaces of vsaid partition walls; gas distributing channels extending longitudinally over Athe upper parts ofthepartition walls and terminating in, nozzles porting ,upwardly from the. upper sides of` said partition walls; and combustionair inlet means-tothe shaft space beneath the partition walls for introducingthe air for combustionin the shaft above thearched walls from the space beneath said walls through the intermediate spaces between the partition walls.

3. Apparatus as claimed in claim 2, and in Which the nozzles in the shaft wall are arranged to discharge fuel gas into the shaft tangentially to the shaft axis.

4. Apparatus as claimed in claim 2 and in which the nozzles in the shaft wall are arranged ,in rows of upper and lower nozzles with the nozzles of each row alternating in position sideby-side with the nozzles of the other row.

5. Apparatus as claimed in claim 2, and in -which the nozzles for the gas distributing chann'els that extend' longitudinally over the partitions are arranged around the center of the shaft ata uniform distance therefrom.

6.!A. combustion shaft comprising: arch-like radial-Walls extending from the shaft walls towards its axial center and meeting at the center and spacedfrom each other leaving sectorlike spaces just.above.=the'lower part ofthe shaft; .fuel-gasf=nozzles .arranged karound the shaftand extending through. the. shaft walls above the vv'upper .surfaces of the radial walls and directly communicating tangentially with the shaft chamberabovethe radial walls; and combustionairinletmeans to; the shaft chamber beloW the lowersurfaces 'ofthe radial Walls for introducingair. fromthe space beneath the radial wallsthrough, the sector-like spaces between the radial Walls, forcombustion ofthe fuel-.gas discharged: tangentially into the shaft chamber aboveA the radial Walls bythe aforesaid fuelgas nozzles: therefor.
