Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsDear authors,
Your paper is well-written and it is a relevant contribution to the current literature. However, it might be improved, especially to clearly clarify the difference between your most recent published papers and this one.

MAJOR COMMENTS:
Line 166 Eq 5: It is incorrect to take CH4 as the fuel of combustion. The fuel of combustion is the waste with the different compositions proposed. I'd assume that you need to use the ultimate analysis to calculate the amount of Carbons and Hydrogens present in the fuel (waste) for each of the four cases analyzed.
Line 177 Eq 12: Please verify the dimensional analysis of the right side of the equation, because it does not make sense. Or write down a reference of this equation.
General: Please clarify the originality of this work, compared with your previous works Luo et al. (2022) and Luo et al. (2021).

MINOR COMMENTS:
Line 29 and 41: Please provide a source for the information presented, even if it is in Chinese.
Introduction: I would recommend adding a paragraph of the works analyzing the impact of multi source organic solid waste variation, and especially in SGF-V grate incinerators.
Line 99: Provide a source explaining the types of incinerators, especially the working principle of the SGF-V grate incinerators that you're analyzing.
Line 105: Where are located (in the diagram of figure 1) the 24 nozzles supplying the secondary air?
Line 120 and 122: Provide a more detailed explanation on how did you calculate Table 2, taking Table 1 as input.
Line 128-129: Provide sources on how to use the FLIC and Fluent coupling method to simulate the combustion. Preferably manuals.
Line 155 Eq 3: What is Y_is and S_yis?
Line 156 Eq 4: Whats is h_is and Q_sh?
Line 158-159: Place an appropriate reference for the use of the standard k−epsilon turbulence model, and the finite rate/vortex dissipation 158
model.
Line 159-160: Write down the user-defined function utilized to establish the wall temperature, which linearly changed along the height, width, and depth directions. If necessary, deepen its explanation.
Line 167: Please provide a reference explaining how to use the unsteady lumped parameter model
Line 171 Eq 8: In the nomenclature, you used the subindexes 1 and 2 as inlet and outlet, but in Eq8 you're using in and out. Is it because you refer to different parts of the incinerator. In any case, include them into the nomenclature.
Line 171 Eq 9: Please specify what are the r, and Greek letter Fi.
Line 172: Please provide a reference explaining how to use the fixed boundary method.
Line 175 Eq 10: What is Tao?
Line 176 Eq 11: What is Q_iin, and Tao?
Line 187: For the calibration, why didn't you measure as well the rear wall?
Line 203: "the ratio and temperature of primary air and secondary air were kept constant", constant to which values?
Line 205: "...data WAS recorded..."
Line 205: The acronym DCS is used for the first time, but its meaning was not defined.
Figure 4(a): Typo "Conlumn" instead of "Column"
Line 244: The phrase "Under the same load conditions" means that you didn't follow the fuel feed rate shown in table 5. Could you specify the fuel feed rate for each condition?
Line 266 (Figure 8): Why did you check the distribution of steam quality only in the front wall with this level of detail, and not in the rear wall?
Conduct a final general revision.

Reviewer 2 Report
Comments and Suggestions for AuthorsThe paper aims at the modeling analysis of evaporation system in a multisource organic solid waste incinerator using CFD method. It provides a good research method for the coupling research on the boiler side of solid waste resource utilization, and provides guidance for boiler design and industrial application. English language and style are fine. I recommend publication in Sustainability after minor revisions to the manuscript. Here are my suggestions:
1) Line128, please spell out ‘FLIC’ when it is first mentioned and enclose the abbreviated form in parentheses.
2) Does the percentage of fuel composition in Table 3 refer to the mass fraction? This should be noted in the text.
3) Line134-135, how is the initial wall temperature distribution determined? And how is it set by a user-defined function?
4) According to reference 31, the equation is suitable for medium pressure boilers. Is it applicable to high pressure and critical pressure boilers?
5) There are a few mistakes. Please check the manuscript and revise them. Just show some examples:
Figure 1 Steam to Turbine.
Figure 4(a) Column number.
6) The quality of Figure 8 is not high enough, please upload clearer pictures.
Comments on the Quality of English LanguageGenerally good.

Comments and Suggestions for AuthorsCan authors show the picture of the SGV-F grate incinerator with the label showing all the parameters of the incinerator? Please add those with the location description.

Reviewer 4 Report
Comments and Suggestions for AuthorsThe topic is current and very interesting, and it is addressed correctly in the well-structured paper.
In paragraph 3.2, which pertains to model verification, it is explained that some thermocouples were inserted to measure the actual temperature and compare it with the temperature calculated through the model.
Typically, this is a rather complex operation as it requires direct intervention within the plant itself, where the physical and chemical conditions are critical.
Is it possible to specify which probes were used?
