Abstract

The two-color method is known as a relatively easy and reliable method for measuring the temperature of a flame. This method has the advantage that it measures the temperature of a flame without measuring the value of its emissivity. However, to measure temperature using the two-color method, a blackbody radiation correction must be performed. In general, radiation correction devices that radiate the blackbody temperature spectrum are quite expensive. Therefore, in this study, blackbody radiation calibration was performed using a tungsten lamp, which has a known emissivity for various temperature ranges. The experimental results clearly indicate that the proposed tungsten lamp configurations can be alternatively applied to calibrate the two-color method as a blackbody source.

Keywords:

Flame temperature, Two color method, Blackbody radiation, Blackbody calibration
