Effect of methanol blending on the high-temperature auto-ignition of ammonia: An experimental and modeling study

Xin Li et al.

Summary: This study aims to investigate the influence of methanol addition on the auto-ignition of ammonia under high temperature and low pressure. The ignition delay times (IDTs) of ammonia/methanol mixtures were studied using a shock tube at different conditions. A simplification model (NH3-M model) was constructed based on the Zhang and FFCM-1 mechanisms, and chemical kinetic analyses were performed. The results showed that the addition of 5% methanol significantly shortened the IDTs of the ammonia/methanol mixtures.

Effect of dimethyl ether on ignition characteristics of ammonia and chemical kinetics

Yifan Jin et al.

Summary: The contribution of dimethyl ether (DME) to the ignition delay times (IDTs) of ammonia (NH3) was investigated. The experiments were conducted under different pressure, temperature, equivalence ratio, and NH3/DME mixing ratios. The results showed that the addition of DME decreased the IDTs and promoted the reactivity of NH3. The promoting effect of DME on NH3 ignition was weakened under higher temperature and pressure conditions. An updated mechanism was proposed to explain the promoting effect of DME on NH3 ignition, and the numerical analysis showed that it was primarily due to an increase in the rate of production and concentration of the radical pool, especially the OH radical pool.

An experimental and modeling study on auto-ignition kinetics of ammonia/methanol mixtures at intermediate temperature and high pressure

Mengdi Li et al.

Summary: The ignition delay times of NH3/CH3OH mixtures were measured using a rapid compression machine (RCM) under various conditions. The results showed that the reactivity of NH3/CH3OH mixtures increased with methanol addition. Different concentrations of methanol had an impact on the ignition behavior of the fuel. Pressure analysis revealed distinct ignition modes for NH3/CH3OH mixtures, and a detailed ignition mechanism was developed to accurately predict the ignition behavior. The interaction between NH3 and CH3OH played an important role in the auto-ignition process, with methanol addition affecting the concentration of ammonia and oxygen radicals in the fuel and influencing the ignition pathways.

Experimental and modeling study on the auto-ignition properties of ammonia/methane mixtures at elevated pressures

B. Shu et al.

Summary: Ammonia (NH3) is a promising carbon-free energy carrier for energy and transportation systems, but its low flammability and high NOx emission potential hinder its pure implementation. Methane can be used as a co-firing fuel with ammonia to enhance reactivity and control emissions. This study investigates the ignition properties of NH3/CH4 mixtures at intermediate temperatures and elevated pressures, revealing that higher CH4 mole fractions increase reactivity and reactivity decreases with higher fuel-oxygen equivalence ratios. Comparing experimental data with existing mechanisms, a modified mechanism is proposed for better reproduction of measurements.

Experimental and kinetic modeling study of NO formation in premixed CH4+O2+N2 flames

Xinlu Han et al.

Summary: The formation of nitric oxide (NO) in methane (CH4) flames has been extensively studied, but discrepancies between simulations using different kinetic mechanisms and experimental results persist. Experimental data was collected for NO formation in post-flame zones of CH4+O2+N2 flames with varying oxygen ratios. Analysis showed that thermal-NO production plays a key role in the increase of NO mole fraction in stoichiometric and fuel-lean flames as oxygen ratio increases.

Ignition delay times of NH3/DME blends at high pressure and low DME fraction: RCM experiments and simulations

Liming Dai et al.

Summary: The autoignition delay times of ammonia/dimethyl ether (NH3/DME) mixtures are significantly affected by the percentage of DME and pressure. The oxidation of DME occurs more rapidly than that of ammonia during the ignition process, leading to the initiation of ammonia oxidation and heat release that accelerates the overall oxidation process towards ignition.

A review on ammonia, ammonia-hydrogen and ammonia-methane fuels

Wai Siong Chai et al.

Summary: The combustion of fuels for energy generation is crucial for human activities, but it results in emissions that cause environmental complications and health risks. The replacement of conventional fuels for zero carbon emission is important, with ammonia offering advantages over hydrogen as a carbon-free fuel, but facing challenges such as low burning velocity and high emissions. Therefore, the study of secondary fuels like hydrogen and methane to assist ammonia combustion is essential.
