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.

MILD Combustion

2010
Mild Combustion processes evolve in a temperature and concentration range outside the limit of interest of standard combustion processes, with the aim of lowering the maximum temperature of the whole process below the value at which massive pollutants formation occurs.

Combustion Processes in Mild Combustion

2005
Mild Combustion is a process completely different both from deflagration, detonation, explosion in a classic form, and also from the processes that generate diffusion flames. Therefore it deserves to be analyzed separately from these processes and quoted with a specific name.

DILUTION EFFECTS IN NATURAL GAS MILD COMBUSTION

Clean Air: International Journal on Energy for a Clean Environment, 2006
The mild combustion conditions, i.e., high reactant preheating and dilution level, yield a high efficiency relying on an increase in thermal energy transfer and drastic reduction of pollutant emissions. In this work, an experimental characterization of methane oxidation in mild conditions was carried out in a simple laboratory-scale system as a ...

HDDI in Mild combustion

2009
Mild combustion is an emerging technology in several fields of practical applications, from material treatment to energy conversion as well as to pollutant abatement [1]. In a survey of potential keys for the mitigation of environmental problem, it represents a flexible and clean process that is the result of a trade-off in the optimization of fuel ...

VOC destruction by water diluted hydrogen mild combustion

Chemosphere, 2007
This study represents a preliminary numerical evaluation of the effect of steam dilution and hydrogen addition on the oxidation of formaldehyde and benzene, chosen as representative of the volatile organic compounds (VOC), in mild condition by evaluating the autoignition time and the steady state attainment. These parameters are important in the design

Analysis of Detailed Hydrogen Combustion Mechanisms with Application to Mild Combustion

2005
In the last years new combustion technologies have been developed to produce energy in an efficient and environmental-friendly way. In this background a very promising process is the Mild Combustion. It is characterized by highly diluted and pre-heated reactants.

Modelling of CO and NO Emissions in MILD Combustion Systems

2010
Recently large attention is paid to Moderate and Intense Low Oxygen Dilution (MILD) combustion [1], also denoted as flameless combustion, as it allows limiting pollutants formation, in particular that of CO and NOx. MILD combustion is generally achieved through a massive recirculation of exhaust gases in the reaction region, which ensures dilution of ...

EXPERIMENTAL AND NUMERICAL ANALYSIS OF SYNGAS MILD COMBUSTION

2011
In this study, a CFD model was developed to predict NOx emissions, temperatures and species mole fractions in a Mild combustion experimental burner which was fed with hydrogen and hydrogen/CO2/H2O mixtures. Numerical simulations are performed with three turbulence models, three combustion models and two kinetic mechanisms.
