Abstract: A dry quenching apparatus for hot coke has an upright housing having openings for charging and discharging the coke. An annular header for exhausting gases from the quenching zone is arranged in the middle portion of the housing. In the lower portion of the housing there is an annular header for supplying a cooling agent and communicating through corresponding passages with a distributor disposed above the annular header for supplying a cooling agent and centrally of the housing. An annular distribution header is arranged above the annular header for supplying a cooling agent and has vertical partition walls dividing the distribution header into sections. Each section has at least one opening through which the annular header for supplying gases and the annular distribution header communicate. At least one opening in each section accommodates a flow governor for a cooling agent.

Abstract: To decrease a loss of coke due to burning and to prolong the service life of an apparatus for receiving incandescent coke and conveying the same to a quenching tower, between a wall structure (1) and lining plates (2) there is disposed a spacing member in the form of corrugated sheets (12), and the lining plates (2) are mounted with the provision for linear expansion under the action of heat from incandescent coke and connected to the wall structure (1) by means of cover pieces (13) overlapping temperature gaps, bolts (14) and nuts (15). Bottom gates (7) of a hopper (5) are provided with sealing members (18) having a surface (A) and (B) contacting the round surface of a girdle (6) tangentially. Specific embodiments of spacing members, sealing members and locking means are described.

Abstract: A method of charging coke ovens with coal through charging holes and simultaneously withdrawing gases evolving from the coal charge through the middle charging holes thereof, holding the coal charge over a period of time sufficient for a coal-charging machine to deliver a next batch of said coal charge for charging the next successive coke oven, completely charging said coke oven while simultaneously charging the next successive coke oven through its extreme charging holes, and withdrawing through said middle charging holes of said coke oven being completely charged, said coke-oven gases and introducing a gas inert to said coke-oven gas in an amount of 15-20% of the total amount of the coke-oven gas being withdrawn.

Abstract: A coke dry quenching apparatus comprises a vertical chamber in the lower portion of which is disposed a quenching gas feeding means. The chamber has in its roof a charging hole and in its bottom a discharging gate. In the walls of the chamber is disposed a plurality of peripheral gas conduits communicated with the inner space of the chamber and with an annular collector having a common gas withdrawal conduit. According to the invention the hollow of the collector is divided by a horizontal partition provided with ports into two cavities communicating with one another, the lower cavity being communicated with the peripheral gas conduits and the upper one with the common gas withdrawal conduit.Due to the fact that the pressure of quenching gas in the lower cavity of the collector is equalized, the proposed apparatus ensures that the quenching gas flow rate through all the peripheral gas withdrawal conduits is practically equal, which provides for a uniform cooling of the whole mass of the coke being treated.

Abstract: A heating wall for coke ovens with horizontal coking chambers comprises vertical heating flues arranged in pairs, every pair of adjoining heating flues being separated by a partition formed with a flow port in the upper portion. Lateral sides of the flow port are provided with vertical slot-like guides which accommodate projections of a slide gate. The guides are formed in their upper portion with stepped recesses the vertical extent of which exceeds the length of the slide gate projections. The slide gate center of gravity is shifted with respect to the longitudinal axis of its projections in the direction opposite to the stepped recesses. The slide gate is provided with means for introducing a hook and vertically moving the slide gate into its uppermost and lowermost position in the flow port. As a result, the flow port vertical position is changed substantially without changing the clear opening of the flow port.
