Samcheonpo Thermal Power Plant, South Korea

Project: Samcheonpo Thermal Power Plant, Unit 5&6 FGD(500MW x 2 Units)
Date: Unit #5 30th October 2019(24 Sets) / Unit #6 15th November 2019(24 Sets)
Location: Samcheonpo , Gyeongsangnam do
Owner: Korea South East Power Company De NOx
System Supplier: BDI Co., Ltd. Acoustic Cleaner
Product: Primasonics ® Acoustic Cleaning System
Principal (Provider): Artronix System Co., Ltd.(South Korea Distributor)
Problem: Ash accumulation on the top of the catalyst in SCR

In order to prevent ash from accumulating in the catalyst of the SCR De Nox system for Unit 5&6 environmental facility improvement work of Samcheonpo Thermal Power Plant, an efficient Acoustic Cleaner is used rather than the Steam Soot Blower, which is difficult to operate and maintain. The installed quantity is Unit #5 24 sets(4ea per layer) / Unit #6 24 sets(4ea per layer), with 3 layers per reactor, the total number of layers of Boiler 1 Unit is 6 layers. The applied model is SAH 120.

We bid only to companies that passed technical bid evaluation and technical review from BDI Co., Ltd. which received an order for environmental facility improvement work project from Korea South-East Power Company with the support of Primasonics, Artronixdid its best to proceed with technology evaluation and bidding to win this project.

All units 5&6 boilers of Samcheonpo Thermal Power Plant are operating and are operating stably without any problems due to the loading of ash in the SCR. Artronix was able to calculate and apply the sounding sequence & time according to the type of catalyst and application conditions, etc. based on the SCR application experience and the technical support of Primasonics. 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 to 3 years, or as long as 4 to 5 years, without any maintenance.

In SCR of Samcheonpo Thermal Power Plant, 1 horn operates by 10 sec, and the next horn operates after 3 sec. (ON time 10 sec / OFF time 3 sec). The period of 1 cycle is set to 8 minutes.
