Ozone can enhance laminar burning velocity, broaden the flammability limit and improve flame stability, but the effect of ozone on soot formation in the combustion process of hydrocarbon fuels was not yet clear. Therefore, the soot from ethylene/oxygen/ozone laminar partially premixed flames was investigated. Besides, the response law of soot formation to different dilution gas ratios, and the effect of ozone participation in the reaction was also investigated. This work found that ozone significantly shortened the flame height by 4 mm in the cases of 10 % dilution ratio. The particle size of soot was larger at low and medium flame heights due to ozone involved in combustion. The main reason was that ozone promoteed soot growth. At medium and high flame heights, the larger the percentage of oxygen and ozone, the lower graphitization degree of the soot. The addition of oxygen and ozone both made the <em>I</em>_D/<em>I</em>_G value increase, which indicated the graphitization degree decreased. The soot from high height of the flame with 10 % dilution ratio and the addition of ozone had the largest <em>I</em>_D/<em>I</em>_G value of 0.970, which indicated a very low degree of graphitization.

In the experiment, 1,2-DME is added at volumes of 5 %, 10 %, and 15 % while engine load is at 25 %, 50 %, and 75 %. In-cylinder pressure and temperature, heat release rate (HRR), knock intensity (RI), combustion duration (CD), ignition delay (ID), brake thermal efficiency (BTE) and pollutant emissions such as carbon monoxide (CO), nitrogen oxides (NO_x), hydrocarbon (HC), and smoke opacity are all evaluated. The findings reveal that increasing the 1,2-DME ratio in the reference fuels enhances HRR, in-cylinder pressure, and temperature. Notably, adding 10 % 1,2-DME to D100 at 25 % engine load significantly increases HRR by approximately 28.65 %.

In this work, ReaxFF MD was adopted to construct gasification reactions with different conditions, and the effect of calcium on the products during the gasification was investigated by counting the distribution of the gasification products as well as the changes of calcium species in different conditions. At the same time, the catalytic mechanism of calcium in char during gasification was further investigated by calculating the charge and electrostatic potential of the gasification agent and the gasification agent after calcium binding, as well as the radial distribution function between different atoms. Research has shown that during gasification, the release of calcium from char combined with oxygen atoms in the gasifying agent leads to a decrease in the O–H or C=O bond energy, which promotes the cracking of the gasifying agent.

Various combustion criteria including flame speed, ignition delay, heat release, NO emission, and reaction pathways have been explored within different compositions of propane/ammonia/air/hydrogen peroxide. This investigation has been performed through the kinetic study applying a detailed mechanism compromising 188 species and 1604 reactions. According to the findings, air replacement by hydrogen peroxide might improve the laminar burning velocity, heat release rate, flame temperature. The substantial reactivity of hydrogen peroxide leads to a significant increase in OH and H radicals, consequently accelerating the reaction rates as the hydrogen peroxide content in the oxidizer increases. The reaction H + O₂↔O + OH (R906) plays the most significant role in enhancing flame propagation in a fuel/air mixture. However, as the hydrogen peroxide content in the mixture increases, the influence of this reaction diminishes, and the reaction H₂O₂(+M)↔2OH(+M) (R929) becomes more dominant. Initially, NO levels increase with the addition of hydrogen peroxide, but they start to decline at higher proportions of hydrogen peroxide. The initial increase may be attributed to the higher flame temperature, while the subsequent decrease could be linked to a substantial reduction in atmospheric nitrogen levels in the oxidizer. In situations where, pure hydrogen peroxide is used as the oxidizer, there is no production of NO_x in pure propane combustion due to the lack of nitrogen.

It was found that the synergistic effect during co-pyrolysis could enhance the production of aromatic hydrocarbons but inhibit the formation of nitrogen-containing and phenolic compounds. Meanwhile, the aromaticity of the char increased with increasing the wood blend ratio, resulting in an enhanced quality of the char.
