This paper presents the experimental results of the addition (increasing thermal power) and substitution (constant thermal power) of a sub-bituminous pulverized coal in a natural gas flame in a laboratory-scale premixed burner. The analyzed variables include radiation intensity, temperature profile, and flame shape. It was found that with the addition of 15% and 30% coal (energy based) into the natural gas flame, the radiation intensity was increased by 37% and 65%, respectively.

The primary objective of this work is to study the blending of natural gas in equimolar
proportions with three high hydrogen content syngases in a radiant porous media burner.
We examined the effects of the composition of the syngases, the fuel-to-air ratio and the
thermal input on the flame stability, the radiation efficiency, and the pollutant emissions
(CO and NOx). In this study, we emulated the syngases with H2eCO mixtures, in which the
H2 to CO ratio was varied between 1.5 and 3. Additionally, pure natural gas was also used as

 El presente estudio evaluó numérica y experimentalmente en un horno de 20 kW (a gas natural y con un factor de aireación de 1.2) la estabilidad del régimen de combustión sin llama ante la variación de la carga térmica usando diferentes flujos de aire (43 scfm, 63 scfm y 83 scfm) y una mezcla de Aire-Helio (Aire 82.02 scfm y Helio 7.06 scfm); esta última se utilizó con el fin de evaluar el comportamiento del sistema ante un incremento en el calor especifico del fluido de carga. El estudio se dividió en dos partes, una parte numérica y otra experimental.

A numerical study of flameless combustion with mixtures of methane and a sub-bituminous pulverized coal was carried out. The analyzed mixtures were 0%, 25%, 50%, 75%, and 100% pulverized coal (energy based). The numerical study was performed using the geometry of a laboratory-scale furnace, which was originally designed to obtain the flameless combustion regime burning natural gas.

In this work, we evaluated the transient heating of a liquid using an in situ laboratory-scale combustion system, and the sensible and latent heat transfer efficiencies were determined through experimental evaluation of the heating of water volume and psychrometric parameters of combustion gases. Tests were performed using natural gas with a composition of 97% (by volume) of methane, and the liquid level was varied to study the effects on efficiency. Experimentation was carried out at atmospheric conditions of 298 K and 850 mbar with combustion gases at 446°C and equivalence ratio φ=0.83.

Methane number (MN) and the critical compression ratio (CCR) measurements for twelve blends of biogas with methane or propane and hydrogen additions were taken in a Cooperative Fuel Research (CFR) F2 model engine according to the standard. In addition, CHEMKIN simulations of MN and the CCR were performed on these blends at similar conditions to the CFR F2 engine operation. Eight chemical kinetics mechanisms were used; it was concluded that the best mechanism to simulate the CCR is USCII, and the best mechanism to simulate MN is San Diego.
