Abstract

The invention discloses a soot flame temperature measurement method, and relates to the technical field of fuel combustion flame temperature measurement, and the method comprises the steps: constructing blackbody radiation intensity through employing wavelength, blackbody temperature, a first radiation constant and a second radiation constant based on the blackbody radiation Planck law; utilizingthe blackbody radiation intensity and the emissivity to construct the radiation intensity at the temperature T and the wavelength lambda; constructing a charcoal smoke and fire flame temperature modelby utilizing the radiation intensity on the basis of a double-color temperature measurement method; and obtaining the soot flame temperature according to the soot flame temperature model. According to the invention, the complexity of soot flame temperature measurement is simplified, and the measurement accuracy is ensured.

Description

technical field [0001] The invention relates to the technical field of measuring the temperature of a fuel combustion flame, in particular to a method for measuring the temperature of a charcoal smoke flame. Background technique [0002] The chemical energy released from fuel combustion provides more than 80% of the world's energy consumption today, but various pollutants are produced during fuel combustion, among which the carbon smoke produced by incomplete combustion is the main source of inhalable solid particles such as PM2.5 one. Studying the characteristics and mechanism of soot formation in flames is the basis for further development of technologies to reduce respirable particulate emissions, and it is necessary to accurately measure the temperature field of soot flames. At the same time, the carbon smoke in the high-temperature flame is also a radiation source, and the flame temperature field distribution can be measured according to its radiation characteristics. ...
