Reviewer 2 Report

The review topic which the authors have presented is of great interest to the academic community, industrial burner designers, and gas turbine operators. The shift from conventional HC fuels to hydrogen is very essential for global climate change policies and sustainable energy scenarios in the future. The following minor and major considerations should be taken care before this manuscript can be published

Major

1. in sub topic of swirl flame of H2-CH4, the authors have missed a lot of articles

2. while writing in the text it is preferred that authors write authors' name instead of only the reference number.

3. it would better to summarize the observations at the end of section 1. 

4. In general, it would be good if authors present a table summarizing work down in flame shape and form. It have been observed that authors have not highlighted the effect of swirl number.

5. In section 2, the authors have missedsome work relevant to H2-CH4 combustion

Minor

1. Figure 7 legend should be corrected, x-axis title should be standard (phi).

2. Ref [20] is book not an article from Combustion and Flame.

 

Author Response

Thank you for your comments. The disadvantages have been corrected.

Major

1. Remarks were considered. Submitted articles added to paper, more detailed review was made.
2. References were remade with author’s name and number.
3. Summ of observations was added.
4. Recommended table was made and integrated into the text.
5. Remarks were considered and articles were reviewed. 

Minor

1. Figure were fixed in accordance with the remark.
2. Reference was fixed.

Reviewer 3 Report

The manuscript deals with the use of hydrogen in industrial applications such as gas turbines. The manuscript is a review of the state of the art regarding the characterization of the combustion process when adding H2 into natural gas mixtures. The manuscript is structured correctly, the problems of adding a fuel that is much more reactive than natural gas are highlighted. Such issues can create security issues in the device such as flameouts or flashbacks.

It is advisable to review the layout according to the template of the magazine, the figures that have been taken from other articles are of poor quality (i.e., Figure 5, Figure 8, Figure 10) and often overlap each other. In addition, the tables appear to be too large and out of bounds. Furthermore, a major bibliographic search is recommended as this is a revision. There are many uncited recent works addressing the issues in the article below are two examples, but more literature integration is recommended:

 

- Feeding H2-admixtures to domestic condensing boilers: Numerical simulations of combustion and pollutant formation in multi-hole burners. Applied Energy 309, 118379. doi: 10.1016/j.apenergy.2021.118379

 

 

-Data-driven subfilter modelling of thermo-diffusively unstable hydrogen–air premixed flames. Combustion Theory and Modelling, 2021, 25(6), pp. 1064–1085. Doi: 10.1080/13647830.2021.1925350

 

In conclusion, the manuscript presents a poor and inaccurate literature, not considering many works published in the last 20 years. Thorough proofreading is recommended before accepting the manuscript.

Thanks for your comments. The disadvantages have been corrected.

Figures and tables have been redesigned according to the magazine template. The quality of the drawings has been improved. Relevant works were additionally cited.

Round 2

Reviewer 1 Report

I appreciate the modifications performed by the authors but they are not enough to suggest this paper for publication. The paper remains poorly written with typos and convoluted sentences throughout. Several figure still remains of poor quality.
