Claims priority, application Great Britain January 5, 1955 4 Claims. (Cl. 202--243) This invention relates to coke ovens, gas retorts and the like, hereinafter referred to as coke ovens, and to doors and like end closures therefor, hereinafter referred to as coke oven doors, of the kind in which the door has a passage or space formed therein to allow gases which collect at the ends of the oven to pass to the space within the oven and between the crown of the oven and the top of the charge, the said passage being provided by one or more ducts formed in brickwork lining of the door, said duct or ducts extending from a position or positions on the surface of said brickwork and below the charging level in the oven to a position or positions on said surface above said charging level.
In one known form of coke oven of the kind described, a primary duct formed in the brickwork lining of the coke oven door extends from and has an opening in the bottom substantially horizontal face of the door which is located just above the sole of the coking chamber, and there are branch duets extending downwardly from the primary duct to, and having openings in the side vertical walls of the door which are adjacent but spaced from the side Walls of the oven. The upper end portion of the primary duct extends to and has an opening in the front inner vertical face of the door, which opening is directed towards the interior of the coking chamber and is located above the top level of the coal charge in the chamber.
It has been found that with such a construction there is a disadvantage in that the upper open end of the said duct in the-door may become choked or closed by coal or coal dust which may enter or pile up against the said opening during the charging or coking operation, and'in consequence the said duct becomes partially or wholly inoperative.
According to the present invention, a coke oven of the kind described is characterised in that the duct or ducts formed in the brickwork lining of the door has or have its or their upper open end or ends located in the side vertical walls or faces of the door which are adjacent to and spaced from the side walls of the oven.
Embodiments of the invention are illustrated in the accompanying drawings, wherein:
Fig. 1 is a fragmentary transverse sectional elevation of a coke oven embodying one form of the invention,
, taken on line I-I of Fig. 2,
Fig. 2 is a fragmentary longitudinal sectional elevation, taken on line IIII of Fig. 1, and
Figs. 3 and 4 are sectional plan views, taken on lines IIIIII and IVIV, respectively, of Fig. 1.
Figs. 5 and 6 are views similar to Fig. l but showing modified embodiments of the invention.
Referring to Figs. 1 to 4, an end door 11 to a coking chamber 12 comprises a metal frame 13 fitted with a plug or lining 14 of brickwork which is directed into an end opening 15 of the coking chamber when the door is closed. The metal frame 13 of the door makes tight facial contact with a marginal portion 16 of the outer face of the coke oven structure which surrounds the opentially so for the major portion of its height, is formed in the brickwork lining 14 of the oven door 11, being located medially of the door in a lateral direction, the bottom end of said duct being open at 22 in the bottom substantially horizontal wall or face 23 of the door which 27 in said side Walls or faces at positions below the top level 18 of the coal charge in the oven.
Other branch ducts 24 extend from the upper end of the vertical primary duct 21 towards both vertical side walls or faces 28 of the door lining 14 and emerge at openings 25 in said side walls or faces at positions above the top level 18 of the coal charge in the oven.
By such a construction, gases which collect at the ends of the oven coking chamber are led to the gas space 19 below the crown 20 of the chamber by way of spaces 29 and 30 formed between the walls of the end opening 15 of the chamber and the bottom and side walls 23 and 28, respectively, of the door brickwork lining 14, the inlet ports 22 and 27, the ducts 26, 21 and 24, and the exit ports 25, and thereby the pressure, which otherwise tends to cause leakage of the gases through the door, is relieved.
By locating the upper open ends 25 of the ducts in the side walls 28 of the door brickwork lining 14, that is, directed into the spaces 30 between the side walls 33 of the oven and the side faces or Walls 28 of the door, the possibility of such openings 25 becoming wholly or partially choked or closed by coal of the charge in the oven is wholly overcome or considerably reduced.
In addition, there may be a vertical duct 32 within each of the side walls 33 of the end opening 15, at each side of the door, having open ends or ports 34 just above the oven sole 31 and other open ends or ports 35 just below the oven crown 20 and above the charge level 18. These ducts 32 will also reduce the gas pressure in the oven immediately adjacent to the door.
By a construction according to this invention, condensation of tarry matters from the gas at the cooler ends of the ovens is overcome, and the usual deposits of carbon and char between the door frame and the door face are not noticed, and a tight joint can be effected.
It will be found that a door or closure according to this invention will assist in increasing the yield of light oil as a by-product, by' preventing partial gas cracking.
In the modification illustrated in Fig, 5, two vertical, or substantially vertical, primary ducts 36 are formed side by side, laterally of the door, in the brickwork lining 14 of the door, the bottom ends :of said ducts being open at 38 in the bottom wall 23 of the door. Ducts 37 extend from the upper ends of the said primary ducts 36 in opposite directions to opposite side walls 28 of the door lining and emerge in said side walls at 25.
For constructional or other reasons it maybe desirable not to have both upper ducts 37 at the same level, as in Fig. 5, but to dispose them at different levels, as shown in Fig. 6.
What I claim and desire to secure by Letters Patent 1. A door or like end closure for a coke oven or the like, including a brickwork lining formed as a plug to enter the end of said oven, said door having a passage or-space formed within to allow gases which collect at the ends of the oven to pass to the space within the oven and between the crown of the oven and the top of the charge, the said pressure being provided by at least one duct formed wholly within the said brickwork lining of the door, said duct having an orifice below the level of a charge in the oven and extending from at least one position on a surface of the said brickwork lining which will not be in direct contact with a charge in the oven and which position is below the level of a charge in the oven to at least one position on a side vertical ce or" said brickwork which will be adjacent to and 1 from side wall of the oven.
2. A door or like end closure for a coke oven or the like, according to claim 1, wherein one substantially vertical duct is formed in the brickwork lining of the door and its upper end branches towards both side vertical faces of the door and has open ends located in both said side faces.
3. A door or like end closure for a coke oven or the like, according to claim 1, wherein two substantially vertical ducts are formed side by side in the brickwork lining of the door and the upper ends of said two ducts lead separately towards opposed side faces of the door and have open ends located in said side faces.
4. A door or like end closure for a coke oven, comprising a brickwork lining formed as a plug to enter the end of said oven, said door having a passage formed Within it to allow gases which collect at the ends of the oven to pass to the space within the oven and between the crown of the oven and the top of a charge therein, the said passage being provided by at least one duct formed wholly within the said brickwork lining of the door, said duct extending from orifices which are located below the level of the charge in the oven on a side vertical face and the bottom face of the said brickwork lining which will not be in direct contact with the charge in the oven to at least one orifice located above the level of he charge in the oven and in a said side vertical face of the brickwork lining.
