  • Nuclear Reactor

    Nuclear Reactor

    A nuclear reactor, a core element of a nuclear power plant, is designed for self-control and the maintenance of chain nuclear reactions, and makes use of heat energy from nuclear fission within the reactor. Doosan Heavy Industries & Construction provides reactor model APR1400, a 3rd-generation and Korean standard nuclear power plant, and the AP-1000 from Westinghouse to Korea, the U.S., the UAE, China and other countries.

    A reactor vessel is designed to withstand high temperatures and high pressures in order to provide a space for containing nuclear fuel and chain reaction. It contains reactor internal components with a bottom head welded at the lower part of its cylindrical body.

    The reactor vessel closure head assembly is a flanged hemispherical component bolted to the vessel by studs, nuts and washers to facilitate refueling and inspection.

  • Steam Generator

    Steam Generator

    The steam generator operates between the primary and secondary coolant loops. The heat generated by the nuclear fission in the reactor core is delivered to the coolant in the primary loop. The heat is transferred between the two loops, converting water into steam and delivering it to the turbines.

    Major Parts
    • Moisture separator (for standard steam generators)
    • AS01 moisture separator (for replacement steam generators)
    • Tube support plate (horizontal)
    • Improved axial tube support plate (for replacement steam generators)
    • Auxiliary feedwater system (for standard steam generators)
    • Upper tube bundle supports
    • Steam dryer
    • Steam outlet nozzle (for standard steam generators)
  • Nuclear Reactor Coolant Pump

    Nuclear Reactor Coolant Pump

    A nuclear reactor coolant pump is installed at the primary system of the nuclear power plant. The large capacity vertical pump is a key part of the nuclear steam supply system and delivers the heat generated by nuclear reaction to the steam generator by compulsively circulating the high-temperature and high-pressure coolant.

    • Provide the motive force for circulating the coolant in the reactor coolant system
    • Primary heating of reactor coolant
    • Reactor coolant pressure boundary
    • Maximum operational reliability is required as the stoppage of RCP leads the stoppage of a nuclear plant
  • Boiler

    Boiler

    A boiler is used to burn fossil fuel to produce high-temperature, high-pressure steam needed in power generation plants or other industries. It consists of the steam pressure vessel, a circulation system, a combustion unit where the fuel is burned, a ventilation unit supplying the combustion air and discharging the exhaust gas and other auxiliary units.

    he technology and experience we have gained while designing, manufacturing, installing and maintaining and repairing boilers for clients worldwide have enabled us to build an extensive boiler portfolio that includes large-capacity drum, once-through and fluidized-bed models for power plants as well as various models for industrial use. We also boast the technology to design eco-friendly models that are highly efficient and capable of removing toxic substances from exhaust gas.

  • Turbines

    Turbines

    A turbine rotates blades inside with hot, high-pressure steam created by the steam generator or HRSG(Heat Recovery Steam Generator), and runs the power generator with the turning force. Doosan Heavy Industries & Construction provides steam turbines designed and manufactured in-house, and is technologically recognized around the world for producing the first gas turbine in Korea, which is considered the centerpiece of power generation technology.

    Steam Turbines

    Steam turbines convert heat energy into rotational energy as the blades are driven by the high-temperature, high-pressure steam generated by the high-capacity power plant boilers. They can be classified as high-, medium- and low-pressure models.
    Doosan Heavy Industries & Construction entered the steam turbine business in 1978, starting with a 200 MW model for the Seocheon Power Plant. Currently, we are capable of designing and manufacturing steam turbines with the specific capacities required for any thermal or nuclear power plant.
    Doosan Heavy Industries & Construction applies an online quality control system for every process in the manufacturing of steam turbines, from materials procurement to finished product. The know-how we have acquired in the manufacturing and installation of steam turbines to date is applied to design models with ever-higher reliability.

    Gas Turbines

    Pressurized air from the compressor is mixed with fuel, ignited and burned to generate high temperature gas which rotates the turbine. It is the key equipment in combined cycle/ cogeneration power plants. With the growing interest in environmental preservation and power generation load issues in recent years, demand for gas turbines with high performance, reliability, fuel diversity and toxic emissions reduction has been increasing.

  • Generators

    Generators

    A core part of a power plant, generators produce electricity by electromotive force from the turning force delivered by a turbine. Doosan Heavy Industries & Construction is capable of manufacturing high-capacity steam turbines, gas turbines, and power generators for diesel engines with a capacity of 30MW to 1000MW, which can cover diesel power generation or even nuclear power generation.

    The company is now capable of supplying a wide range of generators that meet diverse needs of global power generation system markets.

  • Air Pollution Control

    Air Pollution Control

    Air pollution control systems are used to remove air pollutants such as sulfur dioxide, nitrogen oxides and dust contained in the flue gas emitted from thermal power plants or industrial facilities. Environmental facilities are installed from the rear to the stack of boilers. An air pollution control system consists of a DeNOx system (SCR) that removes nitrogen oxides by contacting flue gas with a catalyst, an Electrostatic Precipitator (ESP) that uses electrostatic force to remove dust, and a Flue Gas Desulphurisation (FGD) unit that removes sulfur dioxide from the flue gas by atomizing alkaline solutions such as limestone slurry or seawater into the flue gas. Doosan Heavy Industries & Construction is domestically and globally recognized for its OEM technology and delivery experience..
