On mathematical modelling of flameless combustion
Combustion and Flame, 2007A further analysis of the IFRF semi-industrial-scale experiments on flameless (mild) combustion of natural gas is carried out. The experimental burner features a strong oxidizer jet and two weak natural gas jets. Numerous publications have shown the inability of various RANS-based mathematical models to predict the structure of the weak jet.

Journal of the Energy Institute, 2007 In order to achieve very low emission of nitrogen oxides, a 'flameless' combustion process that uses oxygen, the so called 'flameless oxyfuel' combustion, has been developed.

THEORETICAL AND NUMERICAL INVESTIGATION ON FLAMELESS COMBUSTION
Combustion Science and Technology, 2002Abstract Flameless combustion has been acknowledged as one of the most interesting combustion technologies to meet both the targets of high process efficiency and low pollutant emissions. A theoretical and numerical investigation, carried out to provide a consistent physico-chemical explanation of this combustion regime, is reported here.

Flameless combustion for hydrogen containing fuels
International Journal of Hydrogen Energy, 2010Abstract In this paper, flameless combustion was promoted to suppress thermal-NO x formation in the hydrogen-high-containing fuel combustion. The PSRN model was used to model the flameless combustion in the air for four fuels: H 2 /CH 4 60/40% (by volume), H 2 /CH 4 40/60%, H 2 /CH 4 20/80% and pure hydrogen.

CFD Analysis of the Flameless Combustion in a Micro-Gas Turbine
Volume 4: Cycle Innovations; Industrial and Cogeneration; Manufacturing Materials and Metallurgy; Marine, 2009The concept of flameless combustion as an effective tool for reducing the nitric oxide emission from micro-gas turbines is worthy of an accurate investigation of the thermo-chemical processes inside the combustor. To this aim the authors, basing on their previous experiences on this subject, present a more detailed analysis of the combustion phenomena ...

Reaction zone structure in flameless combustion
Proceedings of the Combustion Institute, 2000We present a study of the combustion limit and reaction zone structure of non-premixed counterflow flames of highly preheated air and methane diluted with nitrogen. First, we measured the flammable region experimentally in the range of air temperatures up to 800 K.

Flameless combustion of hydrogen on the surface of a hydrophobized catalyst
Combustion, Explosion and Shock Waves, 1995The flameless combustion of hydrogen on the surface of a hydrophobized catalyst is investigated experimentally under various conditions. A quantitative interrelationship is discerned between the rate of catalytic oxidation of hydrogen and the catalyst surface temperature.

Flameless combustion behaviour of preheated pulverized coal
The Canadian Journal of Chemical Engineering, 2017AbstractA method for stable flameless combustion of pulverized coal based on coal preheating was recently proposed. The method involves the initial heating of pulverized coal to a temperature above 800 °C. The heated coal is then transferred into a combustion chamber, where it is mixed with secondary air injected at a high velocity to achieve flameless
