UNITED STATES GUS F. LENK, OF DALLAS, TEXAS.
COMBUSTION CHAMBER.
Original application filed September 29, 1923,
September 29, 1923.
T all whom it may concern:
Be it known that I, GUs F. LENK, a citizen of the United States of America, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in Combustion Chambers, of which the following is a specification;
This invention relates to new and useful improvements in combustion chambers for incinerators.
In burning garbage and trash it is essential that the escape of obnoxious odors from the furnace be prevented and in order to accomplish this as well as entirely consuming the garbage and trash, it is necessary that more or less complete combustion be obtained.
The object of my invention is to provide an auxiliary combustion chamber so related to the burning chamber as togive the gases an opportunity to expand and to reduce their velocity, whereby the furnace hydrocarbons are more tho-roughly mixed with the oxygen, which promotes combustion and eliminates odors; and further causes a deposit of ash dust.
A further object is to provide means for cleaning the combustion chamber and flue without shutting down the furnace.
A further object is to provide a combustion chamber having a side entrance with an exit at its opposite end and a roof arched well above the exit, whereby suflicient circulation and retardation is obtained to gain the desired results above set forth.
A particular object o-f-the invention is to provide a grill in the passage between the burning chamber and the combustion chamber which serves to eliminate the passage of burning sheets of paper, rags and the like, which might be sucked up the flue and discharged while burning; and which also functions to break upthe passing gases into small streams of gas, whereby the gases are more thoroughly mixed with air. Further the grill will become heated and the gases contacting therewith, will promote combustion.
A still further object is to provide a removable and repairable arch lining or secondary arch over the entrance between the auxiliary combustion chamber and the flue, which is free from the weight of the main Serial No. 665,617. Divided and this application filed.
Serial No. 665,618.
arch and when burned out may be quickly replaced.
A construction designed to carry out the invention will be hereinafter described together with other features of the invention.
The invention will be more readily understood from a reading of the following speci fication and by reference to the accompanying drawings, in which an example of the invention is shown, and wherein:
Fig. 1 is a transverse vertical sectional view of an incinerator constructed in accord ance with my invention.
Fig. 2 is a longitudinal. vertical sectional view through the combustion chamber; and
Fig. 3 is a plan view, aportion of the roof being broken away in sections.
In the drawings the numeral designates a base or bottom of an incinerator. A front wall 11 and a back wall 12 extend upwardly and are connected by side walls 13 and 14 respectively, all of which extend upwardly from the base. The front and rear walls are connected by an arch 15 of refractory material having therein charging openings 16. This arch also extends between the side walls and forms a burning chamber. Above the arch 15 is the usual roof 17 of the incinerator.
Adjacent the side wall 13 a fuel grate 18 extends rearwardly from the front wall 11. Along the inner side of said grate is built a baffle wall 19 which extends rearwardly from the front wall to about the center of the burning chamber. Between the baffle wall, and the side wall 14: consumption grates 20 are provided. Ash pits 18 and 20 are provided under the grates 1S and 20 respec tively.
In the lower forward portion of the burning chamber an arched opening 21 is pro vided, contiguous to the surface of the adjacent grate 20. The details of the burning chamber are not considered essential as the same is subject to considerable variation. however the side escape of the products of combustions or gases over the grates is important.
Contiguous to the side wall 14; is built an auxiliary combustion chamber formed by a floor 22, an outer wall 23, a front wall 11, a rear wall 12 and an arch 24. The combustion chamber is of course lined with refractory material. In the wall 12 is formed a vertical opening or flue entrance25 which is considerably less in width than the chamber and has its upper end some distance below the arch 24. This causes the gases entering the combustion chamber to be retarded and to whirl in a. vertical orbit therein, whereby their velocity is checked and they are more thoroughly mixed with oxygen. This causes a thorough combustion and prevents the escape of odors into the flue.
It will be seen that this retarding of the gases and air currents will result in the deposit of ash dust on the floor 22 of the combustion chamber and such dust will not be carried into the flue and discharged over the surrounding territory. A door 26 is provided in the front wall 11 and by opening this the floor 22 and the floor 27 of the flue 28 may be cleaned out withoutdisturbing the tire, in the burning chamber and without interference therefrom. This is a very important feature.
fit the top of the entrance 25 to the flue 28 is built a primary arch 29 suitably anchored to carry the load. Concentrically within the primary arch is built a secondary arch 30 of tire brick. The hot gases constantly whipping under the arch will burn out the same and by providing a secondary arch the latter will burn out and may be readily replaced without disturbing the primary arch, which form a permanent structure.
In the opening 21 which preferably has an arched top, I mount a grill 81 of any suitable material. The hot gases and air currents from the burning chamber pass through the meshes of this grill and the latter becomes intensely heated. This grill serves to obstruct the passage of the large pieces of ignited matter such as sheets of paper, rags and the like, which if permitted to pass might be carried out through the flue 2S and set lire to surrounding property. The gases coming into contact with the hot mullions of the grill will be more thoroughly combusted and in passing through the meshes thereof, will be broken up into small streams and more thoroughly mixed with air, which promotes combustion. The flue 28 forms part of a chimney 28.
I am aware that auxiliary combustion chambers have been used but I believe I am the first to provide a combustion chamber at the side of burning chambers having its entrance at one side and a restricted flue, entrance at its opposite end, whereby the gases are retarded and circulated in the combustion chamber to promote combustion, without the aid of an additional fire. The secondary arch and the grill are important and useful features of my furnace. The burning chamber constitutes a main combustion chamber, but is more properly a burning chamber.
hat I claim is:
1. In an incinerator, the combination with a burning chamber having grates, of
an auxiliary combustion chamber contigucue to the burning chamber and having an inlet from the burning chamber extending upwardly from the grate line of the burning chamber, the floor of the combustion chamber being spaced some distance below the inlet and the grate line of the burning chamber, the combustion chamber having a restricted arched opening at its rear end.
2. In an incinerator, the combination with a burning chamber having grates, of an auxiliary combustion chamber contigu-. ous to the burning chamber and having aninlet from the burning chamber extending upwardly from the grate line of the burning chamber, the floor of the combustion chamber being spaced some distance below the inlet and the grate line of the burning chamber, the combustion chamber having a restricted arched opening at its rearend, the arched opening extending from the floor of the combustion chamber, and a smoke stack in rear of said arched opening.
3. In an incinerator, the combination with a burning chamber, of a combustion chamber contiguous to burning chamber and having an inlet connection with the bottom of the burning chamber, a separately arched roof over the combustion chamber being below the floor of the burning chamber and the bottom of the inlet, and an arched restricted outlet at the rear of the combustion chamber having its arched top some distance below the arched roof of said combustion chamber.
In testimony whereof I atlix my signature.
