Dangjin power plant South Korea

 Dangjin, South Korea -6GW

The Dangjin power plant, consisting of four 600MW coal-fired units, is now operating in South Korea. The power station is fitted with low-NOx and coal-dust suppression equipment, and has desulphurisation and denitrification scrubbers.

Orders were placed in 1994 for the first pair of units, and in 1996 for the second pair. On-site construction of units one and two began in May 1995 and they were completed and commissioned in 1999. Operational service began in March 2000. Construction of units three and four was started in June 1995, and the main steel structure was erected in January 1997. These were completed more rapidly than the first two units and began operations in June 2001.

The operational mode of the plant is base load and middle load with fully automated operation. Total investment is around $2.7 billion.

Korea Electric Power Co (KEPCO) engineering subsidiary KOPEC was the prime architect-engineer and has been providing services ranging from preliminary plant design to start-up and tests, based on a standardised once-through supercritical boiler plant design with variable pressure operation capability.

Hanjung is the lead equipment supplier for Dangjin, building on its partnerships with GE and KEPCO in the design of the standard coal plant series. Hanjung manufactured boilers, turbines and generators. The turbines are tandem compound, reheat and condensing type. Dong Ah was the lead constructor.
