Catalytic CVD Synthesis of Double and Triple-walled Carbon Nanotubes by the Control of the Catalyst Preparation [PDF]

open access: yes, 2005
We report the influence of catalyst preparation conditions for the synthesis of carbon nanotubes (CNTs) by catalytic chemical vapour deposition (CCVD). Catalysts were prepared by the combustion route using either urea or citric acid as the fuel. We found

Mini-Review: Heat Transfer Mechanisms in MILD Combustion Systems

open access: yesFrontiers in Mechanical Engineering, 2021
MILD combustion has a wide potential in enhancing thermal efficiency with nearly zero emissions. It has no visible flame since the radiation from the reacting zones is attenuated due to both the intermediate species at reduced temperatures, induced by ...

Critical Issues of Chemical Kinetics in MILD Combustion

open access: yesFrontiers in Mechanical Engineering, 2020
Mild combustion processes occur with mixtures highly diluted and preheated by a strong recirculation of hot exhausted gases (thus mass and sensible enthalpy) within the combustion chamber.

Scalar gradient behaviour in MILD combustion [PDF]

open access: yes, 2013
The results of three-dimensional Direct Numerical Simulation (DNS) of Moderate, Intense Low-oxygen Dilution (MILD) and conventional premixed turbulent combustion conducted using a skeletal mechanism including the effects of nonunity Lewis numbers and ...

MILD pulverized combustion technology: The latest research progress and key scientific issues

open access: yesMeitan xuebao
The MILD combustion is a combustion mode that occurs in a moderate or extremely low oxygen environment, combining the advantages of high combustion heat utilization and very low NOx emissions, and is considered by the international combustion field to be

MILD combustion of oxygen fuel burner using impinging jet method

open access: yesJournal of Thermal Science and Technology, 2019
The possibility of oxygen-MILD combustion without preheating of oxidants is assessed numerically and experimentally in this paper. For the formation of oxygen-MILD combustion, jet impingement method was employed to enhance the internal recirculation flow

TVOCs and PM 2.5 in Naturally Ventilated Homes: Three Case Studies in a Mild Climate [PDF]

open access: yes, 2019
In southern Europe, the present stock of social housing is ventilated naturally, with practice varying in the di erent seasons of the year. In winter, windows are kept closed most of the day with the exception of short periods for ventilation, whereas ...

The role of chemistry in the oscillating combustion of hydrocarbons : an experimental and theoretical study [PDF]

open access: yes, 2020
The stable operation of low-temperature combustion processes is an open challenge, due to the presence of undesired deviations from steady-state conditions: among them, oscillatory behaviors have been raising significant interest.

Coupled effect of torrefaction and blending on chemical and energy properties for combustion of major open burned agriculture residues in Thailand [PDF]

open access: yes, 2018
Thailand is an agriculture-based country. It produces large amounts of open burned agricultural residues. A strategy to use them as biofuel all year round is to enhance their fuel properties by coupling blending and thermochemical pre-treatment.
