Mobley, C., A. Hoffman, AND H. Lownie. SEALING COKE-OVEN CHARGING LIDS, CHUCK DOORS, AND STANDPIPE ELBOW COVERS: SURVEY OF CURRENT U.S. STATE OF THE ART. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/2-77/058.
Description:
The report gives results of a survey of the current U.S. state-of-the-art approach and methodology for sealing coke-oven charging lids, chuck doors, and standpipe elbow covers. The study was part of the program, 'Technical Support for U.S./USSR Task Force on Abatement of Air Pollution from the Iron and Steel Industry.' The survey concluded that: (1) seals associated with coke-oven charging lids, chuck doors, and standpipe elbow covers are all metal-to-metal contact; (2) charging lids and standpipe elbow covers are typically flat, tapered, or shouldered surface contacts, but chuck-door seals are similar to end-closure door seals (i.e., metal strips pressed against a flat metal surface); (3) oven designers indicate that all three components should provide an emission-proof seal, if properly cleaned and maintained; and (4) U.S. coke plant operations augment the inherent seal of these components with luting mud, slurries, and/or gaskets. The study did not develop data relating the extent and type of emissions from these components.
