چکیده
A fuel mixture of ammonia and natural gas as a low-carbon alternative for future power generation transportation is an attractive option. In this work, 50-species reduced mechanism, NH3NG, suitable computational fluid dynamics simulations (CFD), developed ammonia–natural cofiring while addressing important emission issues, such the formation nitrogen oxides (NOx), soot, carbon monoxide, unburnt methane/ammonia. The adoption mechanisms imperative not only saving computer storage running time but also numerical convergence practical applications. NH3NG mechanism can predict soot because it includes precursor species. Further, handle heavier components in gas, ethane propane. absolute error 5% predicting NOx CO emissions compared to full Modified Konnov mechanism. Validation with key performance parameters (ignition delay, laminar flame speed, adiabatic temperature, emissions) indicates that predictions are good agreement published experimental data. average prediction 13% ignition delay within typical data uncertainties 10–20%. predicted temperatures 1 °C. For R2 between 0.985. over-predicts emissions, similar all other literature methods, closer

From the viewpoints of securing a stable supply of energy and protecting our global environment in the future, the integrated gasification combined cycle (IGCC) power generation of various gasifying methods has been introduced in the world. Gasified fuels are chiefly characterized by the gasifying agents and the synthetic gas cleanup methods and can be divided into four types. The calorific val...
متن کاملNatural gas: physical properties and combustion features
The majority of natural gases are mixtures of saturated hydrocarbons where methane prevails; they come from underground accumulations of gases alone or gases associated with oil. There are thus as many compositions of natural gases as exploited hydrocarbon layers. Apart from the methane which is the prevailing element, the crude natural gas usually contains decreasing volumetric percentages of ...
