Mitsubishi Hitachi Power Systems, Ltd. (MHPS), jointly with Daelim Industrial Co., Ltd. of Korea, has received an order for a boiler to be installed at the Shinseocheon Thermal Power Plant, a 1,000 megawatts (MW) class coal-fired ultra-supercritical-pressure (Note) thermal power generation plant to be newly constructed by Korea Midland Power Co., Ltd. (KOMIPO). The boiler will be a core component of the large-scale high-efficiency power generation plant that is slated to commence operation in September 2019.
The Shinseocheon Thermal Power Plant will be built at a site approximately 200 kilometers south of Seoul, in the Seocheon County of South Chungcheong Province. Once completed, the power plant, which is being built in line with Korea's 6th Basic Power Supply & Demand Plan (2013-2027), will supply power to meet the vigorous demand in the area.
KOMIPO is a power generation company of Korea Electric Power Corporation (KEPCO), Korea's national electric power supplier. Its current power generation methods include coal-fired, oil-fired, and natural-gas-fired gas-turbine combined-cycle (GTCC). Earlier, MHPS received an order for two M501GAC gas turbines for KOMIPO's combined heat and power supply plant in Seoul through Doosan Heavy Industries & Construction, a Korean recipient of MHPS's related technology.
Daelim Industrial is a major engineering and construction company in Korea that handles civil works as well as the construction of bridges, highways, tunnels, ports and power generation facilities. MHPS has collaborated with the company on many power plant construction projects. This collaborative work history in partnership with Daelim Industrial, as well as the outstanding performance and operational track record of MHPS's high-efficiency boilers, largely contributed to the team's winning of the latest order.
MHPS has a strong track record and has earned high trust from the global market in coal-fired ultra-supercritical-pressure and supercritical-pressure thermal power plants, which achieve a high level of thermal efficiency in coal-fired power generation while also enabling reductions in CO2emissions.
Going forward MHPS will continue to apply its high-efficiency technologies and undertake aggressive marketing in a broad range of countries and regions where demand for coal-fired power generation systems is expected to increase, as its way of contributing to both stable power supplies and reduction of environmental burdens.
(Note) Under normal atmospheric pressure (1 atm), water boils at 100°C (212°F/373°K) and the temperature and pressure go no higher. When increased pressure is applied, however, the boiling point rises beyond 100°C; and if pressure is increased further and takes the water temperature to 374°C/22.1 megapascals (approx. 220 atm), water no longer boils but rather vaporizes. This is referred to as water's critical point. Supercritical pressure is defined as the state when the pressure level has been increased to roughly 250 atm, driving the water temperature to 566°C; and ultra-supercritical pressure refers to the state when water's temperature rises to 593°C. In recent years, owing to their enhanced power generation efficiency, demand has been increasing for supercritical-pressure and ultra-supercritical-pressure boilers and steam turbines.
