Experimental Contributions for SO_2 and NO_x Reduction From Combustion Flue Gases By Energetic Electron Induced Plasma Process And Electrical Discharge

摘要

Many authors have investigated simulatneous reduction of SO_2 and NOx from flue gas stack emissions. Because of his high costs, this technology has been applied only in few countries (Japan, China, and Poland). Small countries, consumers of cheap combustibles, produce a great deal of atmospheric pollutants: SO_2 and NOx. For this reason there is a great interest for implementation of cheaper technologies, with same impact as electron beams processing has. The paper presents a series of experimental data for SO_2 and NOx removal of flue gas by electron beams, electric discharge. It also presents an economic study for an installation of simultaneous SO_2 and NOx removal pilot plant at a 550 MWe power plant (CET-SOUTH-Bucharest), with an electron beam device and processing capacity of about 10,000 Nm~3/h and 10~6 Nm~3/h, respectively.
