Materials Technology Development
Doosan Heavy Industries & Construction develops energy materials used in power generation plants such as nuclear plants, coal-fired thermal plants and gas turbines, as well as work rolls, mold & tool steel and other industrial components. We strive to develop world-class material engineering solutions, including large-scale ultra-clean steel that uses special refining technology, integrated forgings for pressure vessels which are key components of nuclear power plants, and life cycle assessment technology based on the evaluation of material characteristics. We are recently focusing on the development of high-temperature material, investment casting process for heavy duty gas turbines, In addition, functional materials such as Nano materials and powder material for 3D printing are being researched to strengthen our business competitiveness as well as identify new growth engines.
Advanced Process Technology Development
Doosan Heavy Industries & Construction develops technologies suited to the company’s products and production sites with a focus on welding process/automation, surface treatment, non-destructive testing and special process. We maximize welding productivity with the development of automation devices for ultra-narrow gap welding and high-efficiency cladding & welding and develop inspection/maintenance equipment for damage repair services to extend life of nuclear power plants. As nuclear power plants come to the end of their operating lives, we develop technologies for decontamination and decommissioning of main equipment as well as closure of nuclear plants and we also strive to develop heat-shielding coating systems to apply to blades, a key element of high-efficiency gas turbines.
Heat & Fluid Research
We conduct research on heat transfer performance improvement and fluid flow control technologies that form the basis of product development and design in the areas of energy conversion/transfer/usage systems, fluid machinery and environmental facilities by applying specialized knowledge in heat and mass transfer and fluid dynamics. In heat transfer performance improvement, we are working on the development of heat exchanger design technology using methods that optimize heating surface and resolve 2-phase flow instability in working fluid circulation. In fluid dynamics control, we are developing in-house CFD codes and an analysis model in order to secure thermal flow behaviors in turbine/boiler combustion in a precise and timely manner.
Doosan Heavy Industries & Construction is researching technologies needed to optimize and improve reliability of structures, including service life evaluation for structures, thermal-structural coupled field analysis, elasticity/plasticity analysis, structural vibration/rotor vibration/fluid induced vibration analysis and vibration/noise diagnosis and control. Our recent research focuses on evaluation and optimal design for life of boiler pressure part, plant operation time reduction and fluid induced vibration convergence analysis, along with technologies used to diagnose and evaluate vibration and noise generated on plant work sites.
System Engineering Research
Doosan Heavy Industries & Construction is researching system engineering technologies needed in determining design criteria for reliable operation of plants with minimum price and optimal performance during the lifespan of plants. Our recent research focuses on the development and consolidation of main equipment design tools in order to enhance technical competitiveness and synergy of the company’s EPC projects and main facility projects. These tools can be used to forecast plant performance and analyze and optimize dynamic characteristics by checking plant performance and operational reliability from the plant perspective at the design phase.
Control System Research
Doosan Heavy Industries & Construction is researching control systems and Instrumentation & Control (I&C) known to be the brain and nerve system of nuclear, thermal, renewable energy and desalination plants. Based on the technology to design hardware and software that comprise control systems, various plant applications are explored to realize “Smart Plant,” the ultimate goal of the company. Having already performed a successful installation of new developed integrated monitoring & control system for 500 MW thermal power plants, we aim to lead the global plant control system and I&C markets by expanding the application of the technology to other types of power plants, including nuclear, desalination and renewable energy power plants.
Process Control Research
Doosan Heavy Industries & Construction develops control algorithms for the thermal power plant main equipment and optimal tuning technologies for the stable operation and the advanced control performance. We also research optimizer solutions for the improved power plant operation with an efficiency based on the modern control theory and ICT convergence technology. We develop the simulator with high fidelity to verify the control performance and improve the commissioning procedure by using the plant simulation technology. Our in-house developed technologies are planned to expand into areas, including CCPP(Combined Cycle Power Plant), desalination plants and new and renewable energy. As realization of Smart Power Plant in that way, we contribute to our company’s global competitiveness and additional value creation.
Water Technology Research
Our platform technology R&D aims to improve the efficiency, operational performance, cost reduction for seawater desalination as well as water treatment plants while our new technology R&D is designed to secure new growth engines in water.
