Abstract: Abstract:The characteristics of JTECH streamer corona ammonia desulphurization technology were introduced. The mechanism, principle and process flow of JTECH streamer corona ammonia desulphurization technology were expounded. The practical application result shows that the desulphurization efficiency of this technology is greater than 98%, the ammonium sulfite oxidation ratio is greater than 98%, the ammonia mass concentration in outlet is lower than 8mg/m3, and there is not entrapped ammonium salt in the output flue gas. The problems of the conventional ammonia desulphurization, which include the entrapped water and ammonium sulfate and aerosol emission exceeding standard, were solved thoroughly by application of this technology in power industry.
