Global warming has become an increasingly serious problem, triggering demands for reducing the use of coal, one of the largest emitters of greenhouse gases.
However, many people around the world still lack a stable supply of electricity in daily life. To meet their needs at an affordable cost, coal-fired electricity remains essential for the time being.
NYK IDEMITSU Green Solutions Co., Ltd. aims to achieve sustainable global growth and to solve social problems through various activities such as reducing CO2 emissions both in Japan and overseas and improving energy efficiency, leveraging Japan's advanced coal-related technologies.
- Dec. 2019: Our ULTY-V plus was featured in an article in the January issue of Gekkan Keiso (Instrumentation Monthly, Kogyogijutsusha).
- Nov. 2019: Our company was introduced in an article in the November 5 issue of Netsusangyo Keizai Shimbun (Thermal Industry Economics Newspaper).
- Sept. 2019: Three ULTY-V plus units were introduced in super (ultra-super) critical power transforming once-through boilers.
ULTY-V plus boiler combustion control system
The ULTY-V plus is designed to reduce fuel consumption by 0.5 to 1.5% by additional installation on an existing boiler control system. This completely self-contained system performs self-measurement, self-analysis, and self-diagnosis in a series of operations utilizing AI to achieve the optimum operation of coal-fired boilers used in power and other plants. The system also has optional functions: (1) an efficiency and economics program, and (2) an efficiency and economics evaluation by brand.
We will continue to visualize plant operation and fuel management by analyzing operation data accumulated in the ULTY-V plus, leveraging IoT technology.
Effects of introduction
Achieves stable operation and reduces energy losses.
Improves main steam pressure controllability.
Improves fuel flow rate controllability.
Reduces coal consumption.
Reduces CO2 emissions.
Stabilizes steam temperature.
Reduces exhaust gas temperature.
Reduces unburned carbon residue in ash.
Over 100 units have been installed in domestic and overseas plants!
For manual operation of the control terminals, air-fuel ratio control or the boiler master, we perform calculations for improving necessary control systems and propose circuit configurations before introducing the ULTY-V plus.
New technology development
We also carry out design and development to meet customer needs by leveraging our know-how and experience with the ULTY-V plus, and obtain patents for new technologies.
