Online Pyrometry Calibration for Industrial Combustion Process Monitoring

Round 1

Reviewer 1 Report

This work aims to contribute to the measurement of flame temperature distribution, whose procedure is highly costly and not accurate. Hence, an online pyrometer calibration method is developed to define the characteristics of the flame temperature in an online-manner. This method was proven successful and with a lower cost than more traditional methods. Finally, it is also proposed as a method to calibrate other type of sensors based on un-calibrated ones.

Abstract: theologically?

Introduction: In Eq(1), why are bold letters used for the temperature measurements?

Do not include the conclusions in the introduction when enouncing the main contributions. It is suggested to change the phrasing of such part for a simple description of the research’s objectives.

Section 2: Include value of constants in Eq(2) description

As a general rule, when using Kelvin degrees for temperature, it should be written as uppercase K. This should be consistent throughout the text.

Figure 3: Titles of the images should be included in the main title of the figure and not in the figure itself. This same issue appears in other figures such as figure 6 and 7.

Section 4.2: Have you tried any other method besides Otsu’s? Why did you choose it?

Conclusions: What is it meant by saying that the “measurement accuracy is sufficient?”? How is sufficient defined?

It is not clear how the algorithms for the calibration process were obtained. It is suggested to give more details about the process.

It is suggested to drawn some more detailed conclusions based on the accuracy results.

It is suggested to review the figures and tables’ title to correct typing errors.

It is suggested to include a color scale next to the images to be able to interpret temperature distributions easily.

Reviewer 2 Report

Dear editor,

Thank you very much for the opportunity to evaluate and try to improve the research of others. The article has its merits, although I would have liked a small addition of comparison with other techniques, which I include in the comments to the authors.

Best regards,
