Accurately measure the true gas temperature

The ACTES system is based on a basic principle: the speed of sound propagation in a medium is related to the temperature of the medium.
By accurately measuring the time difference between the emission of the sound wave and the reception of the sound wave at a distance, as well as the distance between the emission point and the receiving point, the average temperature of the medium between the two points can be obtained, achieving true gas temperature measurement without radiation error.

System Configuration

The ACTES acoustic temperature measurement system consists of multiple transceivers installed around the furnace roof to transmit and receive sound waves. According to your needs, ACTES can flexibly configure different numbers of acoustic wave transmitters and receivers for you to display the temperature of different numbers of areas in the furnace section.
A high-performance processor is used to calculate the actual gas temperature between the transceivers after each sound wave transmission.
A set of tomography algorithms designed specifically for the furnace environment calculates all the measurement results to reflect a complete 2D isothermal view of the temperature inside the furnace. The isothermal map is updated every 1-3 minutes.

Benefits of Actes

Breaking the limitations of traditional furnace temperature measurement

  • Using physical properties, it is not affected by the radiation of the furnace wall and other parts in the furnace during combustion.
  • Non-contact real-time measurement, no temperature drift, and accuracy better than 2%.
  • The measurement temperature range can reach 1927 degrees, which can be used within the full load range of the boiler.
  • The measurement space is not limited, not only the average temperature can be measured, but also the complete two-dimensional temperature field distribution of the furnace can be determined.
  • Ultra-long life, no aging of equipment, no daily maintenance required.
  • The signal processing unit runs the Windows operating system, and all data can be intuitively visualized through the Web interface and easily exported in a variety of common formats.
