Round 1

Reviewer 1 Report

This study involves use of algorithmic tools of CSP to investigate the adiabatic autoignition of ammonia/air mixture at constant volume. The manuscript is well written and describes the various aspects of the study in detail including the methodology adopted. Also, thorough literature review is performed to describe what is already known.Hence, the manuscript can be accepted in the current form. Minor comments follow.

It is concluded that addition of H2O2 reduces the ignition delay significantly with minimal increase in NOx. However, do authors see any other limitations with addition of H2O2?

Author Response

We are thankful to the reviewer for his appreciation of our work. With regard to the comment on whether there is an additional limitation in the use of H2O2, as an additive to the initial mixture of NH3/air, to the minimal NOx increase, our answer is now included in the Conclusions section, where we address the issues of corrosion and stability of the H2O2 molecule.

Reviewer 2 Report

Authors described a calculation procedure than clearly enlighten the autoignition process of amonia/hydrogen peroxide mixture.

Methodology approach is very rigorous and conclusions are strongly supported by research outputs. Scientific soundness of this paper is very high.

I warmly recommend it for publication on Energies.
