Study of the Thermal Radiation Hazard from a Combustible Gas Fireball Resulting from a High-Pressure Gas Pipeline Accident

Round 1

Reviewer 1 Report

The present work demonstrates the study on the thermal radiation hazard range of high-pressure combustible gas pipeline fireball accidents.  After peer-reviewing the current paper, the technical content of this paper was good. Furthermore, the paper in this current form needs radical improvement. Authors are requested to carefully revise their manuscript and provide a detailed response letter for each comment. Additionally, I would like to remind the authors to pay utmost attention to the following point while finally revising their paper and before accepting it.

1-  The authors should review the introduction section and write about the literature review. 

2-The authors should present the current paper's aim and novelty as well. 

3-The authors are be advised to write a nomenclature section in the manuscript. 

4-The authors should reconsider the grammatical English in the entire manuscript

5- The reference should be updated and put in recent publications in 2022 and 2023, and I recommended the authors put the following references, which maximize this paper as below: 

 

a)  Fuel, Volume 291, 1 May 2021, 120112.

b) Energy Fuels 2020, 34, 3, 2816–2823.

c)Fuel, Volume 284, 15 January 2021, 118928.

 

d) Science of The Total Environment, Volume 756, 20 February 2021, 142715.

6-The abstract should be reviewed, and I suggest authors provide the background, target, significance, methodology, main results, and so on, in this abstract.

7- The conclusion should be written in paragraphs, not numbered points.

I am looking forward to receiving your received format of the paper, and based on your modifications and answering to comments, your paper will be accepted

Reviewer 2 Report

This paper entitled Study on thermal radiation hazard range of high-pressure combustible gas pipeline fireball accident is interesting. However, some issues should be addressed by the author to improve the quality of the paper. Here are the comments related to these issues:

1.         Abstract: - mention and explain the method used in your study in the abstract briefly!

-           mention the result of the simulation and calculation of the study in the abstract before concluding it.

2.         Introduction: clearly state the gap between the previous study and your study, then explain why it is important to study and compare the models.

3.         Figure 10 is not clear enough; which part do you want to explain? Could you explain and mention the detail of the two figures? We can see that there is a bit of difference and not absolutely similar between calculation and simulation. Why is it happening?

4.         Explain the results of the study's in-depth discussion! Presenting many figures of results without any meaningful discussion is useless.

5.         Conclude the study based on the discussion of the results.

Reviewer 3 Report

The authors studied the high-pressure combustible gas pipeline fireball accident. Here are my comments/questions:

1. The authors mentioned "high transportation pressure". What is the definition? The authors may want to add some descriptions.

2. In Table 1, what is the difference between Pentane and n-Pentane?

3. Which radiation model the authors used in the study?

4. A Nomenclature is helpful for the readers.
