INDUSTRIAL-SCALE TEST ON FLUE GAS DESULFURATION BY PULSED CORONA PROCESS

摘要

At the Sichuan Science-City Coal-fired Power Plant in China, an industrial-scale facility for flue gas desulfuration by pulsed corona process was constructed with a maximum flue gas flow of 20,000Nm~3/h. The main influential technological parameters of SO_2 removal by pulsed corona process are presented in this paper, thus a conclusion is drawn on the basis of the previous research that with flue gas flow less than 20,000Nm~3/h, gas temperature 65～70 water percentage approximately 10% (by volume), flue gas resident time longer than 6 s and stoichiometric ratios of NH_3 to SO_2 among 0.99～1.1, SO_2 removal efficiency over 85% can be achieved and power consumption limited to 5wh/Nm~3.
