Combustion Mode and Reactivity of Methane Fuel in Hot O2/CO2/N2 and O2/H2O/N2 Coflows in a Nonpremixed Small‐Scale Tube Burner

International Journal of Energy Research, Volume 2025, Issue 1, 2025.
The reactivity of methane fuel was numerically studied to compare the effects of CO2 and H2O dilution of hot oxidizer atmospheres on combustion modes and flame characteristics. A nonpremixed small scale burner at 8.6 kW thermal load forming central fuel jet flame in coflow oxidizer atmosphere was employed.

Development of a Novel Cyclonic Flow Combustion Chamber for Achieving MILD/Flameless Combustion

Energy Procedia, 2015
burner. The main pre-heated flow rate composed by diluent and oxygen and the fuel (at environmental temperature) are fed inside the combustion chamber from one side. Diametrically opposed the feeding configuration is reproduced, thus realizing a cyclonic flow field inside the reactor. The outlet is located on the top of the chamber.

Oxide Scale Formation of Stainless Steels with Different Heating Methods – Effect of Hydrogen as Fuel

steel research international, Volume 95, Issue 1, January 2024.
Transition toward CO2‐free heating by replacing natural gas with H2 as the combustion gas, or by electrifying the reheating furnace, affects the oxide scale formation of stainless steels. The results indicate the potential reheating conditions to the use of H2 fuels with minor changes of oxide scale and the possibility to reduce oxidation by induction ...
