Recent Status of Purging SO_2 NO_x in Flue Gas by EB and R D of Electron Accelerator in China

摘要

The main energy resource is coal in China. Flue gas from burning coal is the most fearful pollution. Chinese Government pays more attention to reduction of SO_2 in flue gas from 1990's. Various technical facilities of reducing SO_2 have been imported from developed countries especially from Japanese companies. For example, A largest project is that Chongqing-luohuang electric power station imported limestone-gypsum process FGD technology and facility from Mitsubishi of Japan in 1980s for 300 MW generator spending 36.4 million US$ and 27.3 million RMB. Recently an example is EBA technology in Chengdu thermal plant. Some of Chinese institute is going to improve the technology to treat larger amount of flue gas from one generator such as 200 ～ 300 MW generator. And an R & D program of manufacturing higher voltage accelerator is being implemented. Otherwise, electron accelerator of industry application has been successfully made from 20 kW ～ 100 kW with 2.5 MeV energy in China.
