DUST ooLLnca'oR Application filed November 29, 1926. Serial K051513251. H i

heat boilers for the generation of steam.

The invention is especially useful in saving space and at the same time utilizing theheat in an eifectlve manner, while also makmg the same flexible so that one or more of the kilns or one or more of the boilers may be'cut off when desired.

The invention will be understood from the description in connection with the accompanying drawings in which Fig. 1 is .a plan view; Fig. 2 is an end view partly in'section and Fig. 3 is a vertical section along the line 33 of Fig. 1 or Fig. 2 the parts being shown somewhat diagrammatically.

In the drawings reference character 5 indicates a plurality of cement kilns of awell known type from each one of which waste gases are discharged into a compartment 6 in a housing. Each. compartment 6 has a floor sloping at an angle slightly greater than the angle of repose of soot and dust so that soot and dust will not accumulate on the floors of the compartments. Dampers 8 are A partments 6 all open into a lower common flue 10 that is horizontally disposed and is connected at one end by a passageway leading to the stack 12 with a damper 13 in the passageway. V

Openings or passageways 14 are provided along the side of flue 10 and have transverse Walls 14 extending along the bottom thereof. The dampers 15 vertically movable in guides are provided forclosing the openings whenever desired.

Each one of the passageways or openings 14 leads to a boiler 16 and a suction fan 17 is provided for drawing waste gases through each boiler after which the gases pass into the passageway 18 and then into the stack 19.

PAT1.31 1515 oFFrce j HERMAN B. SMITH, 0F PLAINFIELD; New JERSEY, essrenoza TO. THE tandem a- Hoppers 20'may beprovided for collecting soot and dust after the gases pass over the heat abstracting surfaces of the boilers.

The operationis asfollows :Hot gases from the kilns '5 'pass into compartments 6 and thence downwardly into the flue 10', through the passageways 14, over the heat abstracting surfaces of the boilers 16, into the passagewaylS and thence into stack 19. When it is desired to shut off the boilerswhile the kilns arestill being operated the dampers 15 are closed and the damper 13 isopened, thus per mittingthe hot gases to pass into the stack 12 without heating the boilers. Whenit is desiredto cut ofl only some of the boilersnthe corresponding dampers 15 are closed and the damper 13 may be partiallyopened to perm-it a portion of the hot gases from the kilns to pass into the stack 12 while theremainder heats the remaining boilers that are being operated. When one or more of the kilns 5 are not being operated the corresponding damper or dampers Sare closed, thus permitting the gases from the remaining kilns to pass into and away from flue: 10, as heretofore described. The combinations are various and all conditions need not be specifically described.

With the compartments 6, into which the kilns 5 discharge, arranged directly above the flue 10 less space is required for the installation. When the hot gases from the kilns discharge into the compartments 6- dust and soot therefrom settle in these comparatively quiescent spaces upon the floors 7 which slantv downwardly and from there'the dust and soot pass into the flue 10 where they collect and can be removed from time to time. However,

if dust and soot collect upon the'floors7 they a can be removed by rakes or the like passed through the openings 9. The partitions or walls 14 prevent'a large portion of the dust and soot from being carried into the passageways '14. d i

I claim: 1 Y 1. In. combination, a plurality of kilns, separate compartments into which gases from said kilns are discharged, a common flue below said compartments connected to all of said compartments and a damper between each compartment and said flue.

2. In combination, a plurality of kilns, separate compartments into which gases from said kilns are discharged, said compartments having sloping bottoms, and a flue to which said compartments are connected.

3. In combination, a plurality of kilns, separate compartments into which gases from said kilns are discharged, each of said compartments having a sloping bottom and an opening along one side near the upper edge of said bottom and a common flue into which said compartments discharge.

4. In combination, a plurality of kilns, separate compartments into which gases from said kilns are discharged, a common flue below said compartments connected to all of said compartments and a damper between each compartment and said flue, a stack to which one end of said flue is connected and a damper between said flue and stack.

5. In combination, a plurality of kilns, separate compartments into which gases from said kilns are discharged, a common flue below said compartments connected to all of said compartments and a damper between each compartment and said flue, discharge ports along the side of said flue and a damper in each port.

6. In combination, a plurality of kilns, separate compartments into which gases from said kilns are discharged, said compartments having sloping bottoms at an angle exceeding the angle of reposeof soot and dust, and a fine to which said compartments are connected.

7. In combination, a kiln, a compartment into which said kiln discharges, said compartment having a sloping bottom and an opening through the wall thereof to give access to said sloping bottom.

HERMAN B. SMITH.
