Monitoring the Ignition of Hay and Straw by Radiant Heat
Round 1
Reviewer 1 Report
Reference paper: processes-2586872-
This is a well written paper on a hot subject. The here presented work is a research article tending to critically and analytically examine the effect of radian heat on the ignition behavior of hay and straw. The subject is of significant importance for the field of fire prevention. The paper is of interest to many researchers. The work has apparently been well executed. Perhaps the best part of this paper is the thoroughness of the approach. The literature search is very thorough. However, it suffers from some problems needing special attention from the Authors' side prior reconsidering it for publication in Processes.
1- English can be improved again. Some unintentional errors can be found.
2–To find any eventual correlation between samples, numerous ones should be employed. Please, remove the last sentence of the abstract. Some important results should be shown in the abstract.
3– Despite the originality of the paper is well highlighted in the introduction part. Some further details about the current gap in the field as well as the most important research directions should be added in introduction to increase the impact of the paper and strengthen you work, citing for instance some interesting recent references.
4–Reduce the number of references in the first paragraph (19 refs is a lot)
3–Fig. 6 should be deeply discussed.
4-Fig. 6, the authors didn’t perform any DTA experiments.
5–For the thermal analysis, provide the experimental conditions
6-Add the exothermic sign for the DSC result.
7-Conclusions can be improved accordingly.

Thank you very much reviwer for inspirated comments. We tried to revise our article by submitted numerical comments. Our added text and Figures are highlighted be yellow

Thank you, we tried to improve english by profesional english interpreter
2–To find any eventual correlation between samples, numerous ones should be employed. Please, remove the last sentence of the abstract. Some important results should be shown in the abstract.
Add 2:
We removed last sentence of the abstract
3– Despite the originality of the paper is well highlighted in the introduction part.

Add3:
We are agree with reviwer´s comment and we added in introduction interesting recent references:
4–Reduce the number of references in the first paragraph (19 refs is a lot) –3–Fig. 6 should be deeply discussed.
Add4:
We corrected it and we added new literatures sources about importance of this topic.
3–Fig. 6 should be deeply discussed.
Add5 (name 3):
The DTG curve identifies the temperatures at which the thermal degradation of the sample is maximal. Thermal degradation of hay is two-stage. The first stage of hay degradation is at a temperature of 290°C and the second at 470°C. But the DSC curve, which shows identical thermal degradation stages (and temperatures), identifies the maximum heat release rate in the second stage. It is possible to assume that hay can ignite in the second stage (470°C).
4-Fig. 6, the authors didn’t perform any DTA experiments.
Add 6 (name 4):
I this true. Our thermal degradation of samples were made by radiate sources „hot-plate“. This system does not know to measure amount heat release rate.
5–For the thermal analysis, provide the experimental conditions
Add 7(name 5):
Added it
6-Add the exothermic sign for the DSC result.
Add 8 (name 6)
Yes, we added it.
7-Conclusions can be improved accordingly
Add9 (name 7)
We added it
Reviewer 2 Report
This research work studies the behaviour of hay and straw when expose to radiant heat. The objective of this study is to reveal the ignition temperature of hay and straw under the influence of radiant heat. The research investigates the effects of sample type (hay and straw) and sample quantity on the thermal degradation process, temperature increase within the samples, and ignition temperature of the samples as a function of time. Some issues are suggested.
1. Simple present tense is suggested in the Abstract, especially for the demonstration of objective fact.
2. Please modify the axis title in Figure 5.
3. The TGA-DTA-DSC test is suggested for the hay and straw.
4. The unit in DTG is wrong, please replace it with “%/oC”.
5. The section “6. Patents” is wrong, please refer to other literature.
6. More international references should be cited.
Minor editing of English language including grammatical and typo errors is required.

Thank you very much reviewer for inspirated comments. We tried to revise our article by submitted numerical comments. Our added text and Figures are highlighted be blue.
- Simple present tense is suggested in the Abstract, especially for the demonstration of objective fact.
Add1:
Yes, Thank you
- Please modify the axis title in Figure 5.
Add 2:
We corrected it
- The TGA-DTA-DSC test is suggested for the hay and straw.
Add3:
Excuse us, we found the TGA-DTA-DSC test for only hay and we used it to compare of results the behavior of our hay´s samples with another authors.4. The unit in DTG is wrong, please replace it with “%/oC”.
- The unit in DTG is wrong, please replace it with “%/oC”.
Add4:
Sorry, it was mistake.
- The section “6. Patents” is wrong, please refer to other literature.
Add5:
Sorry, it was mistake.
- More international references should be cited.
Add6:
Yes, we added them.
Reviewer 3 Report
The aim of the article was to experimentally determine the ignition temperature of hay and straw due to radiant heat. The influence of the sample type and the selected sample mass on the course of the thermal degradation, temperature increase inside the sample, and ignition temperature over time were observed.
The topic is interesting for the readers. Anyway major revision is necessary. Authors should make changes and additions to the text.
1. In the "state of the art" there is a lack of papers of international scientists. Please add some papers.
2. The Figure 1 is not necessary.
3. Experimental methods section needs addition. Readers would like to know more about principles of used methods.
4. Authors wrote "... The temperature of the heated plate and its increase over time were determined following the methodology described by Marková [16]..." Is this own patented method or adopted from another procedures. Please explain it.
5. Authors wrote "... Table 3. This is a table. Tables should be placed in the main text near to the first time they are cited..." Please correct it.
6. Units should be given in brackets.
7. The results given in the Figure 3 with the mathematical formula and R2 coefficient should be described.
8. There is a lack of the description of axis (e.g. on the Figure 5).
9. What about statistical estimation of obtained results?
10. Suddenly ... before conclusions section Authors wrote "... The thermal degradation of hay can be compared with the research of Xie et a. [30]. TGA-DTG-DSC curves of rape straw under a heating rate at 10°C.min-1 (Fig. 6) identify comparable temperatures of thermal degradation of the hay with our experimental results....". It is necessary to give more information before (in the Materials and Methods section).
11. Authors cited 30 papers (mainly Czech and Slovak Authors). Is this topic popular only in this countries? Please explain it. Addition of more papers of the international Authors is necessary.
