Modeling of Ammonia MILD Combustion in Systems with Internal Recirculation

Combustion Science and Technology, 2023
The present work focuses on the combustion of alternative renewable fuels, ammonia in this case, in a system, such as the Laboratory Unit CYclonic (LUCY) burner.

PYROLYTIC AND OXIDATIVE STRUCTURES IN HDDI MILD COMBUSTION

International Journal of Energy for a Clean Environment, 2010
The typical structure of un-premixed counter-diffusion flames in standard conditions can be significantly modified when injected flows are diluted and/or pre-heated. The increase of the fuel and/or oxidant flow dilution up to extreme conditions can lead to the formation of nonignitable mixtures. The oxidation processes can be sustained just in case the

MILD COMBUSTION FOR FUEL-NO_xREDUCTION

Combustion Science and Technology, 2004
One source of pollution in the combustion of fossil fuels is the formation of nitrogen oxides. Their production is strictly bound to the presence of molecular nitrogen in the combustion air and to the so-called fuel nitrogen, that is, the N chemically bound to the fuel.

Mild Combustion of Industrial Hydrogen-Containing Byproducts

Industrial & Engineering Chemistry Research, 2007
In this work, a laboratory-scale burner has been used to investigate the sustainability of mild combustion with the coke oven gas (COG), an industrial byproduct mainly constituted by methane and hydrogen (CH 4 / H 2 40/60% by volume). Operating conditions for stable mild combustion have been identified and operating parameters maps have been deduced ...

Plasma Assisted MILD Combustion

53rd AIAA Aerospace Sciences Meeting, 2015
A new test platform for plasma assisted MILD combustion is developed. The burner consists of three coaxial channels: a center fuel jet, a coflowing dielectric barrier discharge (DBD) reactor, and a vitiated air section. The preheating burner upstream of the vitiated air section enables an increase of the oxidizer temperature up to 1300 K near the exit ...

Mild Combustion of Surrogate Liquid Fuels

2010
Recently significant efforts have been made in order to obtain high thermal efficiencies in high temperature combustion processes without the adverse effect of, in particular, high NOx emissions caused by high temperature flames [1]. It was found that a massive exhaust gas recirculation coupled with a preheating of the combustion air generates ...

Effects of hydrogen addition to methane on the thermal and ignition delay characteristics of fuel-air, oxygen-enriched and oxy-fuel MILD combustion

International journal of hydrogen energy, 2021
The present study investigated the effect of adding hydrogen to methane on the thermal characteristics and ignition delay in methane-air, oxygen-enriched and oxy-fuel MILD combustion. For this purpose, numerical simulation of MILD furnace is performed by

Review on MILD Combustion of Gaseous Fuel: Its Definition, Ignition, Evolution, and Emissions

, 2021
Combustion of fossil fuels has been continuously generating over 70% of the total energy for our human society, concurrently emitting vastly greenhouse gases and ecologically harmful pollutants.

Numerical and experimental investigation of a mild combustion burner

Combustion and Flame, 2007
Abstract An industrial burner operating in the MILD combustion regime through internal recirculation of exhaust gases has been characterized numerically. To develop a self-sufficient numerical model of the burner, two subroutines are coupled to the CFD solver to model the air preheater section and heat losses from the burner through radiation.

NO emission from non-premixed MILD combustion of biogas-syngas mixtures in opposed jet configuration

, 2021
In this paper NO emission from MILD combustion of the mixture biogas-syngas is deeply elucidated, five NO routes were considered, specifically: thermal, prompt, NNH, N2O and reburning.
