Abstract

The present invention provides a three-dimensional combustion field temperature measurement method based on extinction correction time analysis, including steps: S1: establishing a two-color radiation temperature measurement system based on endoscopic tomography; the two-color radiation temperature measurement system based on endoscopic tomography includes: Burner to be tested, one-point multi-endoscope, spectroscope, first signal detection system, second signal detection system, Ethernet switch and data acquisition and processing device; S2: first signal detection system and second signal detection system Send the collected multi-angle signals to the data acquisition and processing device; S3: the data acquisition and processing device performs data processing on the multi-angle signals to obtain the time-analyzed three-dimensional combustion field temperature after extinction correction. A three-dimensional combustion field temperature measurement method based on extinction correction time analysis of the present invention can well solve the problems existing in the current temperature detection in the combustion field, and realize more accurate three-dimensional combustion field temperature after extinction correction with high temporal and spatial resolution Measurement.

Description

technical field [0001] The invention relates to the technical fields of computational imaging, combustion diagnosis and radiation temperature measurement, in particular to a three-dimensional combustion field temperature measurement method based on extinction correction time analysis. Background technique [0002] Temperature is a very important indicator in the field of combustion diagnosis, which has an impact on the efficiency of the combustion process and the reduction of pollutant emissions in the combustion process. Existing temperature measurement methods can be divided into contact measurement (such as thermocouple measurement) and non-contact measurement (such as optical measurement method) according to whether they are in direct contact with the measured area. The non-contact optical measurement method is not in direct contact with the flow field and does not interfere with the flow field, so the measurement error is small, and it is also a widely used temperature ...
