Calculation of minimum ignition energy of premixed gases

Journal of Hazardous Materials, 2003
The minimum ignition energy of premixed gases has been calculated by using two theoretical expressions and compared with the experimental data. One expression considers the amount of energy that the minimal flame should have, and the other the heat loss from the surface of the minimal flamelet.

Ignition Probability and Absolute Minimum Ignition Energy in Fuel Sprays

Combustion Science and Technology, 1992
Abstract Ignition in a one dimensional spray by a short duration source is modeled numerically. The probabilistic nature of spray ignition is discussed using a deterministic approach. The ignition source is modeled by a hot gas region of a defined thickness simulating a pilot flame or a low temperature spark source.

Requirements for a minimum ignition energy standard

Process Safety Progress, 2003
AbstractFires and explosions are serious hazards in the process industries. Mitigation methods, such as suppression and venting, can be expensive. Ideally, the best option would be to avoid fire or explosion, which may be accomplished by either removing the explosible fuel/oxidant mixture, or the ignition source.One of the most overlooked and ...

Minimum ignition energy of LDPE dust/ethylene hybrid mixture

Journal of Loss Prevention in the Process Industries, 2021
Abstract An experimental device for evaluating the minimum ignition energy (MIE) of LDPE dust/ethylene hybrid mixture was built with the innovative mixing mode. The MIE of the hybrid mixture that contained ethylene below its lower explosive limit (LEL) was studied.

Minimum ignition energy for laser spark ignition

Proceedings of the Combustion Institute, 2005
Abstract Combustion ignition by electrical sparks and nonresonant laser sparks is preceded by breakdown, electron heating, relaxation of internal plasma energy, shock wave generation and propagation, and subsonic flows. Measurements and model calculations of these processes (which occur over times of 10 −12 –10 −1  s) in laser sparks show that the ...

On the minimum ignition energy (MIE) for propane/air

Journal of Hazardous Materials, 2010
A copy of the standard ASTM spark generator for determination of MIEs of gases and vapours was built and measurements to determine MIE of propane/air at normal atmospheric conditions were performed. However, the ASTM standard does not prescribe any statistical procedure for deriving MIE values from primary test data.

Minimum ignition energies in flowing kerosine-air mixtures

Combustion and Flame, 1976
Abstract Measurements of minimum ignition energy were carried out on kerosine sprays injected into a flowing air stream under conditions of atmospheric pressure and temperature. All the measurements were performed using optimum values of spark duration and with the spark gap adjusted to slightly exceed the quenching distance.

Minimum ignition energy of mixtures of combustible dusts

Journal of Loss Prevention in the Process Industries, 2015
Abstract Most industrial powder processes handle mixtures of various flammable powders. Consequently, hazard evaluation leads to a reduction of the disaster damage that arises from dust explosions. Determining the minimum ignition energy (MIE) of flammable mixtures is critical for identifying possibility of accidental hazard in industry.

Minimum Ignition Energy (MIE) prediction models for ignition sensitive fuels using machine learning methods

Journal of Loss Prevention in the Process Industries, 2021
Abstract Quantitative Structure-Property Relationship (QSPR) regression models for Minimum Ignition Energy (MIE) prediction of 60 flammable compounds have been developed using machine learning algorithms Random Forests (RF), Artificial Neural Networks (ANN) and a non-machine learning algorithm - Genetic Function Approximation (GFA). RF algorithm was
