The Result

Both Units #1 & 2 Boilers of GoseongHai Thermal Power Plant are operating, and they are operating stably without any problems due to the loading of ash in the SCR. Based on SCR application experience and Primasonics’ technical support, we were able to calculate and apply sounding sequence & time according to catalyst type and application conditions. Plate type catalyst is applied to the SCR of this power plant, but there are places where the honeycomb type is used in power plants with a small capacity or an old construction. In the case of SCR using honeycomb type, it operates repeatedly at a cycle of about 5 ~ 6 minutes per cycle, and in case of SCR using plate type, it operates at a cycle of
8 ~ 10 minutes. The Acoustic Cleaner is operated at the same cycle and is operated stably for 2-3 years, or as long as 4-5 years, without any maintenance.
