G-AS-EIERED OVEN OR K I IiN.
applic tion and March '16, 1921,. (Serial raise-are.
To all 70710722 it may oo-210mm:
,Be it known that I, JOHN HENRY MAR- Low, subject of the King of G-reat'Br-itain .and IrelancLand resident of Stoke-bn-Trent, in the county of Stafford, Eng-land, has in vented i certain new-and useful Improvements in Gas-Fired Dvens or Kilns (for which I have made application for ,patent in Great Britain, numbered 8,037, dated the 18th day of March, 1920), of which the following is-a specification.
l\[-y invention Irelates to improvements in or applicable :to ;gasfired :ovens or ,kilus for [use z'i-n :the manufacture of tiles, Jottcry and other ware and ;for :other purposes, the object being improved means for firing -or heating the interior {of the oven .or kiln ,so as to produce a very great amount of heat to affect the ware therein; -means :for supplying gas from :a ,gas producer; and means for conveying, regulating OYrCOfltI'Ol- .lingthe passage of-the ,piroductSof combus- -tion from .the ovenmr kiln.
'h Ly invention will be fully described with ir-eference to the accompanying drawings in which,
Fig. 1 -is .a transverse section \through :the vheat zone-of a-tunnel oven or kiln construct ed according [to any said invention,
Fig. 2 is ttiSGGtlOl'lZLl .planofsame,
Fig. 3 isasectionalelevation-through line A.A aof 2 showing 'one portion of the archway or tunnel ito fbe hereinafter referred to, and
Fig. 4 is a sectional elevation-ofthe top portion of the archway nofqthe ,oVQnxor kiln illustrating the means for conveying, regulating or controlling the passage of the products of combustion from the heat zone of the oven.
In these figures a is the oven or kiln, X the interior thereof where the flame is produced by the ignition of gas and air, I) the usual vehicle or carrier for the ware.
The gas is supplied from a producer P (Figs. 5 and 6) through the passage or flue d (see Figs. 1 and 2) up the channels a and into chambers f arranged at each side and longitudinally of the oven or kiln, each of the said chambers f carrying a series of gas pipes g which may be of varied heights and of any suitable shape or size to deliver the gas into the interior of the oven X. Air is admitted through suitable channels it h (Fig. 3) which are open to the air at the rear portion of the side walls of the tun- -nel and communicate at their forward ends with the spaces or air outlets on opposite sides of the burner tubes, (the air being caused to travel a suflic-ient distance along such channels h to :be heated prior ;to pass- ;ing up the outlet channels or ;recesses 72- h where the heated air mixes with the inflowing gas and combustion :takes place ,producing .a flame. an the interior vof the oven .to fire the ware which may be on the (carrier 101' ;in saggars placed thereon.
The ;gas producer may be of any appropriate type, gas beingsuppliedwto the :burner pipes giby wayiof a {flue d,'w.the latter ha-ving'dampers for controlling the supply of gas to said pipes 9.
As will beseen trom Fig. 1 they gaschambers 'f are arranged in the shelf -or base S of the oven'zwith :the [gas ,pipes 9 extending vertically therefrom but it is obvious such -;pi;pes 9 maybe arranged at as'light'inclination to the horizontal plane at desired. The :outlet end .of each pipe may be inclined was shown -.at ig. 1 :or otherwise shaped to :di-
a'ect :the 1 gas to -meet the incoming heated ,air
and *prcduce agreatfiame. Tlieisaid pipes 9 -may be of any suitable (cross section ;.-and constructed of fireclay :or :other n'efractory material.
In some cases I may dispense with the use of [the pipes .g ,and use the perforations or apertures will the top of the chamber f to .emit the :gas.
Arranged on the ginsidezof ,each series of pipes 9'1 provides shield orguard y ;to pro- :toct the ware, iwhich guard niay avary :in height in accordance with the height of pipes g.
The products of combustion are drawn from the interior of the oven or kiln by suction through horizontal pipes 70 (see Figs. 2 and 3) arranged at a predetermined distance from the heat zone or that portion of the oven where the combustion takes place. The said pipes is are arranged one over the other in an exhaust cavity at all around the arch-way (see Fig. 3) and if desired several series of pipes so placed may be arranged at various intervals in such cavity m. The horizontal pipes or tubes at their forward ends communicate with the interior of the tunnel, and their rear ends and the spaces between the tubes or cavity m (Fig. 4) suitably communicate with outlet flues 0, in the rear thereof, said flues having dampers, and when arched,
Cit
they communicate with a chimney located centrally at the rear portion of the kiln. The said cavity m may communicate with. the chamber 0 at the top of the archway, such chamber being provided with dampers q at any desired portion of its length. By employing several dampers 5 any one 01'' them may be opened to allow the products of combustion to escape to the chimney or any of the dampers may be so adjusted to delay or prevent the passage of the products of combustion as will be understood.
What I claim as my invention and tie sire to secure by Letters Patent is 1. In a tunnel kiln, means for heating the same by gaseous "Fuel, comprising a transverse flue which is connected with a gas supply, gas supply openings between the flue and vertical burner tubes which communicate with the gas supply, ways having outlet openings on different horizontal planes for supplying air about the burner tubes, and a wall which extends vertically above the open upper ends of the burner tubes.
2. A tunnel kiln having adjacent to its truck entrance end, a gaseous Fuel supply flue connected with a gas supply, said flue being positioned below the floor ot the kiln, channels which connect the fuel supply fine with burner tubes which are open to the interior of the kiln, upstanding walls spaced from the side walls of the kiln, and extending upwardly above the ends of the burner tubes air supply ways for the burner tubes, one of the ways terminating adjacent to the upper ends of the burner tubes and the other ways communicating with the space between the burner tubes and the upstanding walls, and means located near the opposite end of the tunnel from the burner tubes for discharging the products of combustion and vapors therefrom.
3. In a tunnel kiln, a longitudinal chamber provided above its floor with walls spaced to extend inward from the side walls,
4. In a tunnel kiln for the purpose set forth, vertical walls having inward extending walls located near the front end of the tunnel, a transverse flue below the plane of the kiln, a gas supply in communication with said transverse flue, channels which establish communication between the flue and chambers formed by the side walls of the tunnel, upstandlng guard walls, burners for gaseous fuel, said burners having open d1scharge ends positioned below the upper edges of the guard walls, and means for supplying air to the burner tubes, comprising a way which has its discharge adjacent to the upper portion of said tubes and a way which discharges into the lower portion of spaces between the upstanding guard walls and the burner tubes.
5. In a kiln of the tunnel type, a gas supply flue, vertical burner tubes, air supply ways which terminate adjacent to the upper end of the burner tubes, upstanding guard walls of greater height than the height of the burner tubes, the same beingofi'set from the burner tubes, and air supply ways which discharge into the space between the burner I tubes and the upstanding walls.
In testimony whereof I have hereunto set my hand in the presence of two witnesses.
