ULTY-V plus AT boiler fuel control optimization system

Product winning the Innovative Power Technology of the Asian Power Awards 2023

Product winning the Director-General of Agency for Natural Resources and Energy Award of the FY2021 (41st) Outstanding Energy-Efficient and Decarbonizing Industrial Machinery & Systems Awards

The ULTY-V plus AT is designed to reduce fuel consumption by 0.5 to 1.5% by retrofit 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 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.
In addition, NYK Idemitsu Green Solutions has been developing other novel technologies such as BAIOMIX, a new product that leverages IoT technology to analyze the operation data stored in ULTY-V plus AT, visualize critical data on plant operations and fuel management, and help achieve optimal mixed combustion ratios in mixed-combustion boiler operations involving biomass fuels.

Characteristics

This system can be implemented on a variety of boilers, such as supercritical (or ultra-supercritical) variable-pressure once-through boilers, subcritical boilers, circulating-fluidized-bed boilers. In terms of fuel types, the system is compatible with boilers that burn coal and other fossil fuels and also boilers that use biomass, RPF, byproduct gas-heavy oil mixtures, etc.
The plant itself need not be remodeled; the system can be easily connected to existing DCS.
It significantly helps to stabilize plant controllability, improve boiler efficiency and reduce CO2 emissions.

Effects of introduction

Enables boilers to maintain a stable combustion cycle with the optimum fuel flow rate achieved by correction signals from the ULTY-V plus AT.
Prevents excessive fuel injection due to pressure fluctuations by maintaining a stable combustion cycle for a long time, thereby reducing the rate of fuel consumption.

Achieves stable operation and reduces energy losses.

Improves main steam pressure controllability.

Improves fuel flow rate controllability.

Reduces fuel 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!

Control consulting

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 AT.

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 AT, and obtain patents for new technologies.
