Coke Oven Pushing Emission Control System

This report deals with the entrapment, pickup, and transfer of hot gases during a typical coke oven push. Background information that led to the development of the Great Lakes Coke Oven Pushing Emission Control System is presented along with the problems that were encountered and solved during the design, construction, installation, and start-up of a pilot plant entrapment structure on a battery of 40 Simon Carves coke ovens. This unique entrapment structure has operated successfully since April 1972, and has been visited by representatives from almost all coke manufacturers in the U.S., as well as interested groups from several foreign countries. In addition to these operation groups, we have been visited by various state and federal pollution authorities, such as the Environmental Protection Agency, Battelle Institute, and National Institute of Occupational Safety and Health. At the present time we are erecting a similar entrapment structure on the north side of our plant, comprising 18 Koppers and 35 Wilputte ovens.
