CONTINUOUS KILN.V
SPECFICATION forming part of Letters Patent No. 703,533, dated July 1, 1902.
Application filed September 20, 1901. Serial No. 75,984. (No model.)
do hereby declare the following to be'a full,
clear, and exact description of the same.
Our invention'consists in the novel arrangement of pipes,combustion-chambers, and passages hereinafter fully described and specifically pointed out.
The object of our invention is to provide for the economical use of fuel-oil or powderedl coal for burning bricks and other ware in continuous kilns.
Referring to the accompanying drawings for a more complete explanation of our in.-
vention,Figure lis a longitudinal vertical sec-V tion. Fig. 2 is a longitudinal horizontal sec- Fig. 3 is a transverse vertical section.
A, Fig. l, represents the kiln in which the bricks or other ware are to be burned; B, B', and B2, Fig. 1, combustion-chambers below the door of kiln, with openings or slot C, Fig. 1, connecting the combustion-chamber Vwith the kiln.
D and D', Fig. 3, are the burners, and E, E', and E2, Fig. 3, are the pipes through which fuel-oil or powdered coal is introduced into the combustion-chambers.
G, G', and G2, Fig. 3, areliorizontal lines or pipes connecting the combustion-chambers and running longitudinally under the kilnfloor.
H and H', Fig. l, are the draft-dues connected with the longitudinal flues G, G', and G2.
The fuel-oil or powdered coal introduced into the combustion-chambers is converted into gas, which rises to the openings in the floor of the kiln to the bricks or other ware which are to be burned.
The supply of fuel-oil or powdered coal is controlled from the top ofthe kiln by suitable compression-cocks connected with the pipes which are iitted around top of kiln. The said pipes run down from'the ftop of the kiln through the walls or lling between Walls or outside of the kiln-walls and into the combustion-chambers. Y
The openingsinto the combustion-chainbers from the top or side, through which the pipespass, are made so as to exclude air not requiredfor blowing in the fuel from entering at these points.
A continuous kiln works economically only when the feed-air enters/the open portion of the kiln where the burned brick or other ware are being taken out, passes through the cooling vbricks or other Ware, becoming hotter in its passage, until-it is consumed by the fuel, and is finally carried up the chimney of the kiln as spent gas and water-smoke.
The object of the ilues or pipes G, G', and G2 is to draw the heat from one combustionchamber to another by the flame passing through said pipes or dues, to equalize the heat in the kiln, to feed oxygen into the combustion -chamber by `drawing feed-air from the open chamber 'through and underneath the bricks or other Ware previously burned, to promote perfect combustion and to cool the bottom of the kiln after the fire has passed and the bricks or other ware are burned, so that the workman can work Without inconvenience from heat. The said fines G, G', and kG2 are-connected in each chambery by a cross draft-flue leading to a damper connected with the. draft-stack of the kiln. A paper partition is placed at each cross draftflue, closing the area of the kiln-tunnel, makingwa stopping-point for the draft till the iire has advanced another section when the paper is burned out. To make the draft stop at'the same point in the longitudinal flues below kiln-floor, we place a small paper partition on each longitudinal iiue at the side of the cross-due that the Alarge paper partition above is on. 'j
In'some continuous kilnsl fuel-oil ory powdered coalis introduced through. the top or crown of the kiln. As gas from fuel naturally ascends, the heat must be drawnthrough the kiln with a strong do'wndraft,which brings the gases down tothe kiln-door and out of the kiln before perfect combustion has taken place. In other continuous kilns there are combustion-chambers which admit fuel and feed-air into the sides of the kiln. This method is a waste of heat, as the heat of the cooling bricks or other ware already burned cannot be drawn through the ire as it should be and must necessarily be allowed to escape and because the cold air admitted into the combustion-chambers requires additional heat to bring it up to the proper temperature for combustion.
The devices composing our improvement are not only simple and inexpensive, but more useful and more eective than any other contrivance heretofore employed for a kindred purpose.
Having thus described our invention, we claim and desire to secure by Letters Patentl. Acontinuous kiln havingaseries of combustion-chambers extending crosswise below kiln-Hoor in which liquid or powdered fuel is burned in suspension, communicating directly with the kiln by means of openings in kiln-Hoor and combined with longitudinal iiues orpipes below kiln-Hoor and between the longitudinal walls of the kiln, connecting said combustion-chambers, substantially as described.
2. A continuous kiln comprising combustion-chambers extending crosswise and below kiln-floor, in which fuel is burned in suspension, connected with the kiln by means of openings across said floor and joined by hues or pipes running horizontally underneath said floor, connecting said combustion-chambers, and joining damper-controlled draft-fines, substantially as described.
3. A continuous kiln having a series of combustion-chambers extending transversely and below kiln-floor connected with the kiln by means of openings across said floor and joined by passages below said licor connecting said combustion-chambers and communicating with damper-controlled draft-fines;
combined with fuel pipes or flues leading to the top and to the outside of the kiln, for the purpose of supplying fuel to the combustionchambers, substantially as described.
4. A continuous kiln comprising combustion-chambers extending crosswise and below kiln-floor, in which fuel is burned in suspension; with a series of openings across kiln-Hoor connecting said combustion-chambers with the kiln, joined by ilues or pipes below kilnfloor connecting combustion-chambers and communicating with damper-controlled draftfines; combined with pipes iiues and burners for the introduction of fuel, said pipes and iiues running to the top and outside of the kiln through and between the kiln-walls substantially as described.
5. A continuous kiln havingaseries of combustion-chambers running across and below kiln-floor in which fuel is burned in suspension, joining one another by means of horizontal pipes or ilues below said floor, said pipes or fines communicating with dampercontrolled draft-fines; said combustion-chainbers connected with the kiln by means of openings across kiln floor combined with pipes and flues running to the top and outside of the kiln, for the introduction of fuel; means of controlling the supply of fuel from the top and outside ofthe kiln substantially as described.
In witness whereof we have, this 27th day of August, A. l). 1901, set our hands.
