Drehmel, D., C. Gooding, AND G. Nichols. PARTICULATE CONTROL HIGHLIGHTS: RECENT DEVELOPMENTS IN JAPAN. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/8-79/031A (NTIS PB80148802).
Description:
The report describes results of visits to Japan to assess research and development of new particulate control technology, and to evaluate the applicability of the Aut-Ainer particulate control device to diesel engines. New technology observed includes hooding systems for coke oven charging and pushing, fugitive emissions control in a Q-BOP furnace building, novel electrostatic precipitators (ESPs), magnetic separators, and hybrid control devices. Fugitive emissions are well controlled in two iron and steel plants visited. Novel ESPs utilize approaches such as wide plate spacing, advanced charging systems, and water cooled collection electrodes. Magnetic separators are currently used for water pollution control and are under consideration for air pollution control. The Aut-Ainer device has evolved from an experimental approach to the device development stage over several years. The device currently has limited applicability to particulate control from diesel engines; however, its basic collection characteristics seem to be based on sound principles. With limited additional development in the general area of removing the previously collected material, the device appears promising.
