Two-dimensional and three-dimensional gas temperature distribution measurement method

Abstract

The present invention relates to a two-dimensional and three-dimensional measurement method for gas temperature distribution and is characterized by, using a diode laser, only one-dimensionally measuring and two-dimensionally or three-dimensionally mapping gas temperature and concentration distributions within a space for which a two-dimensional or three-dimensional measurement is impossible. Thereby, it is possible to easily two-dimensionally or three-dimensionally measure, without space constraint, gas temperature and concentration distributions even within a structure, such as a heating furnace of a steel mill, for which a two-dimensional or three-dimensional measurement is difficult.

Description

technical field [0001] The present invention relates to two-dimensional and three-dimensional gas temperature distribution measurement methods, and more particularly, the present invention relates to improving the two-dimensional or three-dimensional measurement method of gas temperature distribution in structures such as heating furnaces in iron and steel plants that are difficult to perform two-dimensional or three-dimensional measurement. Three-dimensional gas temperature distribution measurement method. Background technique [0002] Therefore, gas temperature measurement in a structure such as a heating furnace of a steel plant is usually realized by a temperature measuring device installed in the heating furnace. [0003] An example of such a temperature measurement method is disclosed in Korean Patent Publication No. 10-2005-0095159 (published on September 29, 2005, hereinafter referred to as 'Patent Document 1') and the like. [0004] However, with the temperature me...

AI Technical Summary

Problems solved by technology

It can simplify the measurement system by reducing the measurement variable, but the difference between the measured value and the actual temperature distribution of the gas also increases, so the measurement error becomes large, and there is a problem that correct measurement cannot be expected

[0009] On the other hand, the temperature discrete method is to predict the measurement temperature interval in advance, and then divide the temperature interval arbitrarily to reduce the measurement variable, which is used to simplify the measurement system method, which can predict the line temperature distribution on the transmission line of the diode laser, but for To understand the two-dimensional temperature distribution, it is necessary to measure the temperature in all directions in two dimensions. Therefore, there is a problem that the two-dimensional temperature distribution cannot be measured in structures such as heating furnaces in steel factories.

[0010] In addition, the temperature measurement method based on the conventional temperature dispersion method has a problem that it may be difficult to confirm the temperature distribution state because the position where the temperature is measured cannot be determined even if the temperature is measured in temperature intervals
