Doosan Achieves Unmatched Efficiency in Gas Turbine Parts
Free Case Study
Doosan Enerbility faced a problem all too common in gas turbine manufacturing. They were trying to lower their turbines’ CO and NOx emissions while maintaining efficiency and power output, but conventional means of manufacturing didn’t allow for the design complexity needed.
Download the case study "Doosan Achieves Unmatched Efficiency in Gas Turbine Parts" and get deep insight into how Doosan integrated additive manufacturing solutions.
Challenge
Compared to traditional means of energy production such as coal, gas power plants emit less fine particulate matter, making gas turbines a cleaner source of energy, relatively speaking.
The key ingredient to this better emission profile lies in the gas turbine’s combustor. To meet the government’s emission regulations, the combustion needs to remain under a predetermined emissions threshold, which requires a complex design.
Solution
The Doosan development team realized early on that traditional manufacturing methods like CNC weren’t capable enough for their plans. Since the company already operates South Korea’s largest 3D printing facility, they could rely on several EOS 3D
printing systems to solve their production problem.
Results
- Reduced nozzle production lead time by 50 %
- Complex internal channel design enabled them to lower the level of unmixed fuel by 68 %
- Lower NOx emissions to as low as 15 ppm and CO emissions to 10 ppm
