The furnace temperature of coal-fired boilers in power plants is an important operating parameter for boiler flame monitoring and control, which directly affects the combustion efficiency and the safety of boilers. Based on the research status at home and abroad and the previous research foundation, this paper studies and designs the temperature measurement system of acoustics method. The principle of temperature measurement by sound method is discussed in this paper, and the generalized cross correlation (GCC) method for measuring flight time of sound waves is introduced. The software and hardware of the temperature measurement system are designed in detail. The experiment is carried out according to the measured data of power plant and the results show that the system can measure the average temperature of acoustic paths in the furnace. The feasibility of the system is verified. And this study provides a basis for the reconstruction of furnace temperature field.
