Patent number: 11807812Abstract: The present technology describes various embodiments of methods and systems for improved coke quenching. More specifically, some embodiments are directed to methods and systems for improving the coke quenching process by partially cracking coke before it is quenched. In one embodiment, coke is partially cracked when placed in horizontal communication with one or more uneven surfaces. In another embodiment, a coke loaf is partially broken when dropped a vertical distance that is less than the height of the coke loaf. In another embodiment, a mass of coke is partially broken when first placed in vertical communication with one or more uneven surfaces and then placed in horizontal communication with the same or different one or more uneven surfaces. In some embodiments, the one or more uneven surfaces may be mounted to a coke oven, train car, hot car, quench car, or combined hot car/quench car.Type: GrantFiled: January 4, 2021Date of Patent: November 7, 2023Assignee: SUNCOKE TECHNOLOGY AND DEVELOPMENT LLCInventors: John Francis Quanci, John Shannon Essman, James Eric Bond, Khambath Vichitvongsa, Chun Wai Choi

Patent number: 11441078Abstract: The present technology is generally directed to systems and methods for optimizing the burn profiles for coke ovens, such as horizontal heat recovery ovens. In various embodiments the burn profile is at least partially optimized by controlling air distribution in the coke oven. In some embodiments, the air distribution is controlled according to temperature readings in the coke oven. In particular embodiments, the system monitors the crown temperature of the coke oven. After the crown reaches a particular temperature range the flow of volatile matter is transferred to the sole flue to increase sole flue temperatures throughout the coking cycle. Embodiments of the present technology include an air distribution system having a plurality of crown air inlets positioned above the oven floor.Type: GrantFiled: January 22, 2021Date of Patent: September 13, 2022Assignee: SUNCOKE TECHNOLOGY AND DEVELOPMENT LLCInventors: John Francis Quanci, Parthasarathy Kesavan, Ung-Kyung Chun, Rajesh Kumar Kandula, Mayela Carolina Fernandez, Khambath Vichitvongsa, Jeffrey Scott Brombolich, Richard Alan Mrozowicz, Edward A.

Patent number: 11053444Abstract: The present technology is generally directed to methods of increasing coal processing rates for coke ovens. In various embodiments, the present technology is applied to methods of coking relatively small coal charges over relatively short time periods, resulting in an increase in coal processing rate. In some embodiments, a coal charging system includes a charging head having opposing wings that extend outwardly and forwardly from the charging head, leaving an open pathway through which coal may be directed toward side edges of the coal bed. In other embodiments, an extrusion plate is positioned on a rearward face of the charging head and oriented to engage and compress coal as the coal is charged along a length of the coking oven. In other embodiments, a false door system includes a false door that is vertically oriented to maximize an amount of coal being charged into the oven.Type: GrantFiled: January 18, 2019Date of Patent: July 6, 2021Assignee: SUNCOKE TECHNOLOGY AND DEVELOPMENT LLCInventors: John Francis Quanci, Chun Wai Choi, Parthasarathy Kesavan, Katharine E. Russell, Khambath Vichitvongsa, Jeffrey Scott Brombolich, Richard Alan Mrozowicz, Edward A. Glass
