Features

01.Low-temperaturede-nitrationcatalyst is adopted. The reaction temperature is 190℃~280℃ and de-nitration efficiency is over 90%.

02.De-nitrationcatalyst could be recycle used, and could be changed without shutdown. Meanwhile, TYHI will recover the failed catalyst.

03.Net discharge is realized by use of sintered metal wire-mesh.

04.Several bypasses are equipped for easy maintenance and repair without shutdown.

05.Processed flue will be exhausted through the previous chimney without heating-up.
