Problems solved by technology

[0008] The advantage of this measurement method is that it is convenient to measure the temperature; the disadvantage is that the requirements for the measurement environment are relatively strict, and the measurement error in the furnace environment is relatively large.
The resolution of the plane measured by the straight-line laser propagation is low and the cost is expensive

Abstract

The invention provides an acoustic technology based furnace box temperature online monitoring system. The acoustic technology based furnace box temperature online monitoring system is an independent system without affecting operation of any unit equipment. An acoustic source used for temperature detection is an autonomously designed electric acoustic source which is high in power, adjustable in frequency range and capable of providing sufficient sound pressure levels. An acoustic wave detector which is an electret enhanced acoustic transmission detector is high in sensitivity and resistant to high temperature. An acoustic wave guide tube has functions of insulation of heat and combustion by-products and protection of a microphone.

Description

technical field [0001] The invention relates to a temperature detection system, in particular to an acoustic technology-based on-line furnace temperature monitoring system. Background technique [0002] Boiler combustion optimization in power plants is the key to safety, energy saving and emission reduction in thermal power plants. More and more large-scale units have adopted combustion modification technologies (such as low-nitrogen burners, over-combustion air injectors, thick-thin separation technology, etc.) to ensure economical, safe and stable operation of the units, reduce the generation of NOX, and meet environmental protection requirements. But for a long time, there is no reliable and accurate means of measuring the temperature (field) of the furnace, so that the optimal combustion loses the basis for direct monitoring and discrimination. Temperature is one of the important basic parameters to describe the thermodynamic process, and it is an important factor relat...
