A numerical study on combustion behaviours of hydrogen-enriched low calorific value coal gases

Accurate experimental (p, ρ, T) data of natural gas mixtures for the assessment of reference equations of state when dealing with hydrogen-enriched natural gas

“…These research activities manifested in a notable number of studies. Some recently published papers which particularly address the aforementioned issues for enriched methane are: experiments of turbulent explosions, focusing on the influence on mixture reactivity by Li et al [17] and explosion studies of methane-hydrogen mixtures by Lowesmith et al [18] on safety; a study on transition pathways to future energy infrastructure by Maroufmashat and Fowler on availability [19]; development of measuring standards to support fiscal metering by van der Veen et al on analysis and metering [20]; a comprehensive review on combustion engines for H2-enriched natural gas by Mehra et al [21], a study of low-calorific value coal gas combustion by Karyeyen and İlbaş [22,23], and the studies investigating the effects of composition on engine performance, combustion, and emission by Hora and Agarwal [24] and Cellek and Pınarbaşı [25], respectively, deal with equipment and operation.…”

An experimental study on premixed CNG/H2/CO2 mixture flames

“…Ilbas and Karyeyen numerically investigated the effect of H addition on combustion behavior of low heating value coal gases and concluded that H addition improves fundamental ame characteristics; but, this situation causes increased NOx emissions in turn [12]. Park and Kim numerically investigated ame structure and emission characteristics of H /CO/CH blending synthetic gases by examining the e ect of gas blending and the amount of N dilution.…”
