Publication number: 20240110103Abstract: Systems and methods for removing carbonaceous clinker material from a coke oven are described. A coke oven can be provided including an oven floor, coke, and clinker material deposited on the oven floor. After a temperature of the coke oven has reached a first temperature (e.g., after heating coal in the oven to produce coke), the method includes increasing the temperature of the coke oven to a second temperature that is higher than the first temperature for a predetermined amount of time. After the predetermined amount of time, the temperature is reduced to a third temperature that is lower than the first temperature.Type: ApplicationFiled: May 8, 2023Publication date: April 4, 2024Inventors: John Francis QUANCI, Daniel C. CHARLES, Gary Dean WEST, Sharla EVATT, Mark Anthony BALL, Jason Francis CRUM

Patent number: 11819802Abstract: Systems and apparatuses for neutralizing acidic compounds in flue gases emitted from a heat recovery coke oven. A representative system includes a spray dry absorber having a barrel that includes a plurality of wall plates that form sidewalls of the barrel. The wall plates include a steel plate and a corrosion resistant alloy cladded to the steel plate and the wall plates are oriented such that the corrosion resistant alloy faces toward and is in fluid communication with an interior area of the barrel. The alloy is resistant to corrosion caused by the acidic compounds in the flue gas and can prevent the steel plate from being corroded by these acidic compounds.Type: GrantFiled: June 17, 2022Date of Patent: November 21, 2023Assignee: SUNCOKE TECHNOLOGY AND DEVELOPMENT LLCInventors: John Francis Quanci, Mayela Carolina Fernandez, Daniel C.
