Korea South East Power runs an eco-friendly power plant armed with state-of-the-art, high- efficiency environmental facilities – including a DeSOx & DeNOx System, and electrical dust collectors- but a new fluidised bed boiler is key to the operation.

Korea’s latest and largest coal-fired, eco-friendly,high-efficiency powerfacility – officially titled the Yonghung Thermal Power Plant Units 3and 4 – has been operating at optimal levels recently. This is all thanks to thenew core facilities and boiler equipment.

Run by Korea South East Power, the units are now part of an 870MW-class coal-fired power plantwhich uses ultra super criticaltechnology.

Moreover, the facility is aneco-friendly power plant armed with
state-of-the-art, high- efficiency environmentalfacilities (including desulfurisation, DeSOx & DeNOx System, and electrical dust collectors).
A company spokesman told IPA: “The completion of the Yonghung Thermal Power Plant Units 1 and 2 has contributed
to easing the imbalance between power supply and demand in the Seoul metropolitan region, and has helped
stabilise the nation’s electricity supplynetwork.

Generators 3 and 4 at the plantmake a significant contribution tostabilising the power supply during the peak power demand season in summer.” Power output
The Yonghung Thermal Power Plant Units 3 and 4 generate 13.6 billion kWh of electricity per year, enough to supply 4 million households.

In 2004 Doosan an initial contract for the supply of boilers for the site in an international bid hosted by KoreaSouth-East Power in 2004, beating out Japanese rivals.
Hard on the heels of this successful project, Doosna was recently contracted to supply equipment worth 100 billion won (£50m) for a project involving the supplyof Korea’s largest 340MW- class Fluidised- Bed Boiler for Yeosu Thermal Power Plant No. 2 operated by Korea South EastPower.
Doosan President & CEO Geewon Park commented: “The contract involved the supply of a 340 MW-class Circulating
Fluidised-Bed Boiler and supplementary facilities.

Unlike a Pulverized Coal Boiler, which is used in most conventional power plants, the Circulating Fluidised-Bed
Boiler is an eco-friendly boiler product which significantly reduces the emission of pollutants such as nitrogen oxide and
sulphur oxide.

Another advantage is that it can use low-grade coal as fuel, effectively cutting fuel costs.” Cutting fuel costs with a Circulating Fluidised-Bed Boiler at Yeosu replacing the use of heavy oil, the plant will not only cut down fuel cost significantly, but also reduce pollutant emissions. Hence the utility facilities, once revamped, will transform into an
economical, eco-friendly power plant.
Under the contract, Doosan plans to design and produce the Circulating Fluidised- Bed Boiler and supplementary equipment at its Changwon Plant, and deliver them by December 2011. Doosan has also signed a licensing agreement with Foster Wheeler, a global market leader in Circulating Fluidised-Bed Boiler technology, in 2006.
Executive Vice President Dongsoo Suh said, “With the acquisition of the new project, Doosan has set a precedent in
the supply of a 340 MW-class Circulating Fluidised-Bed boiler, the largest scale of its kind in Korea and among the largest in
the world.”
He added: “As the use of low-grade coal is steadily increasing, Doosan will continue to win more orders for Circulating Fluidised- Bed Boilers not only in Korea but also in overseas markets in the future.” Doosan also won projects for
the construction of coal-powered thermal power plants adopting Circulating Fluidised-Bed Boilers in Thailand and the
Philippines in 2007.
On June 14th, 2009, Doosan Heavy Industries and Construction signed a contract worth 74 million euros (US$102
million) with MAPNA Boiler of Iran for the overall supply of eight heat recovery steam generators (HRSGs) for four combined cycle thermal power plants in the Middle Eastern country. “The project entails the supply of two HRSGs to each of the four combined cycle thermal power plants located in Kahnooj, Iran.

Doosan plans to begin designing the equipment
based on its own technology in June, and is scheduled to supply them in phasesfrom April to December of 2010,” a
spokesman told IPA.
Doosan Heavy Industries and Construction secured the top spot in terms of global market share in 2003 thanks to the acquisition of HRSG orders worth 240 million euros(US$ 331 million) for the MFPNA combined cycle thermal
power plant, the world’s largest singlesuch project.

The company also won successive orders in the Middle East in
2007 and 2008. Dong Kyu Lee, head of the HRSG BU at
Doosan Heavy Industries and Construction, told IPA: “Doosan was able to win the project thanks to the strong engineering
capacity we have demonstrated during the execution of our other projects in Iran.” IPA
