Against the backdrop of the "dual carbon" goals, the thermal power industry is actively exploring the application of new technologies to achieve energy conservation, emission reduction, and sustainable development. From July 24 to 25, 2025, the "2025 Seminar on the Application of New Thermal Power Technologies Under the Dual Carbon Goals" was grandly held in Taiyuan.

At this forum, Beijing Allinby Technology Co., Ltd. showcased its innovative acoustic temperature measurement solutions for power plant furnaces and achievements in acoustic applications, and delivered a special speech at the conference. The solution focuses on the accurate monitoring and intelligent analysis of the temperature field inside power plant boilers, empowering the green and low-carbon transformation of the thermal power industry through technological innovation and injecting scientific and technological impetus into the realization of the country's "dual carbon" goals. With its cutting-edge technical concepts and significant practical value, Allinby's sharing attracted great attention from all participants, becoming a prominent highlight of this forum.

In the afternoon session of the forum, Mr. Ren, the Technical Director of Allinby, delivered a keynote speech to the participants, providing an in-depth introduction to the company's temperature measurement solution for power plant boilers based on acoustic technology. He emphasized that the new energy power generation industry is currently in a stage of vigorous development, and this trend has also made thermal power plants frequently face many challenges in their operation, such as the demand for deep peak regulation in a short period of time, the maintenance of stable combustion under long-term low load, and the complex working conditions caused by coal blending. The acoustic temperature measurement solution launched by Beijing Allinby can timely and accurately capture the temperature field information in the boiler. With the support of this key data, it can more scientifically and effectively guide the operation and regulation of boilers, providing a new and highly potential technical means for power plants in deepening energy conservation and emission reduction work and realizing the goals of cost reduction and efficiency improvement.

The acoustic temperature measurement solution is based on the functional relationship between sound velocity and medium temperature. By arranging multiple sets of acoustic transmitting and receiving devices on the furnace walls around the furnace section, it obtains the two-dimensional temperature field distribution of the temperature measurement plane using CT reconstruction technology. The system has a measurement range of -100℃ to 2500℃, an accuracy of 1%, and a measurement cycle as short as 0.3 seconds for a single path, and is not affected by furnace vibration, expansion, or particulate matter. The software system features functions such as image display, data processing, and DCS communication. It can also realize three-dimensional display of the temperature field in the boiler, facilitating real-time monitoring of combustion status, providing information on combustion deviation and over-temperature, enabling historical data review, and comes with self-inspection and fault alarm functions, which can link with other auxiliary systems for automatic adjustment.

The independently developed acoustic temperature measurement solution by Beijing Allinby Technology Co., Ltd. has been successfully implemented in multiple projects within China's power industry, with cooperative clients covering many major power plants under various power generation groups. Practical feedback from frontline users has fully verified the core advantages of the system: in addition to high measurement accuracy and a wide range, its features of convenient installation and stable operation reduce operation and maintenance pressure. By optimizing combustion control through precise data support, the solution has helped cooperative power plants significantly reduce coal consumption, providing a new and highly potential technical means for power plants to deepen energy conservation and emission reduction efforts and achieve cost reduction and efficiency improvement goals.

At the "2025 Seminar on the Application of New Thermal Power Technologies Under the Dual Carbon Goals", the splendid display of Beijing Allinby's acoustic temperature measurement solution not only demonstrated the company's technical accumulation and innovative strength from years of dedicated work in the acoustic field but also, through targeted industry solutions, provided new ideas and practical technical paths for the green transformation of the thermal power industry under the "dual carbon" goals. In the future, Beijing Allinby will continue to empower the power industry with technological innovation, helping the power generation sector accelerate towards a more intelligent, efficient, and low-carbon direction.
