Coke Oven Smokeless Pushing System Design Manual.

摘要

The report describes the design and operation of a system to eliminate atmospheric emissions during the pushing of coke from the 45-oven A-battery at Ford Motor Co.'s Rouge Plant in Dearborn,Michigan. The 10-year-old A-battery consists of 45 13-ft high ovens,each producing 12tons of blast furnace coke at a gross coking time of 18hours with a 'push'scheduled each 15minutes. The Coke Guide Fume Hood,where the entire coke guide is enclosed with a hood that extends out over the quench car,was used to eliminate the pushing emissions. Prior to the push,the hood is connected to a stationary fume main that is under a partial vacuum;the hot coke emissions generated during the push are conveyed to a high-energy wet-type gas scrubber where the gas stream is cleaned before being emitted to the atmosphere. Clearances between the hood and quench car are held to a minimum to provide sufficient indraft velocities to overcome normal lateral wind effects.
