DOE'S Electron-Beam-Irradiation Development Program

摘要

The Department of Energy's (DOE's) electron-beam irradiation development program activities are conducted as part of the Advanced Environmental Control Technology (AECT) Program which is managed within the organization of the Assistant Secretary for Fossil Energy. The AECT program supports the development of cleanup systems to economically meet future emission limits so that the industrial and utility sectors can burn coal, which is abundant, rather than to burn premium fuels which are not. The electron beam (E-Beam) development program seeks to promote the development of systems for the simultaneous removal of NO/sub x/, SO/sub x/, and particulates from such flue gas streams. Electrons pass through a thin window into the flue gas causing the conversion of gaseous NO/sub x/ and SO/sub x/ into new sulfur and nitrogen particulate compounds which are then removed by conventional means. The Primary R and D activities within DOE's program involve two jointly funded efforts with Avco-Everett/EBARA and Research-Cottrell. The High Voltage Engineering Corporation plays a prominent role as a subcontractor in both efforts. The Avoc-Everett effort involves the testing of a configuration which utilizes ammonia injection upstream of the reactor and which produces a dry fertilizer by-product. The Research-Cottrell effort involves the testing of a configuration which utilizes a lime spray dryer upstream of the reactor and which produces a landfill waste product. An additional DOE E-Beam effort is being conducted at Florida State University where the use of electron irradiation for particulate precharging is being evaluated. 9 figures. (ERA citation 08:022954)
