Cost Effective Flue Gas Cleaning via. Irradiation with Fast Electrons, Electron Beam Dry Scrubbing Process (EBDS)

The study and prototyping proposed for Phase I addresses the two key issues in achieving this requirement, namely the E Beam window which must have high transmission capability (at the lower E Beam source voltages), and survivabiity i the flue where concentrations of HF, H2S04 and HN03) exiswt and second, a self-shielded, sealed tube capable of long life operating at a nominal 100KV to minimize cost, size, weight and power supply requirements. In Phase I we will develop prototype windows, perform tests to demonstrate their ability to withstand 1 atmosphere of pressure and determine their E Beam transmission characteristics. For the E Beam source, we will scale the tube from one used in an EBDS system utilizing a 35 inch duct (two E Beam sources at 300 KV and 90KW of output power) to one that would be suitable for an 8 inch duct (with twin E Beam sources) or a single 4 inch duct. We will model the mechanical and electrical characteristics for a tube operating at a nominal 100 KV at 5 and 10 KW of output power. Our theoretical analysis (utilizing existing diode theory i conjunction with computer simulation) between cost and scaling will pay particular attention to long life operation, low cost and small size, which are the necessary system characteristics for both Government and Commercial acceptance.
