Spontaneous Combustion of Coal

2020
This is another aspect of Permian Gondwana coal that is rarely given significant attention in books about coal, although numerous short scientific papers dealt in the past and the present with the subject.

A REVIEW OF SPONTANEOUS COMBUSTION OF COALS

Fuel Science and Technology International, 1995
ABSTRACT Coal is one of the carbonaceous materials which, under certain conditions, can combust spontaneously as a result of its oxidation with atmospheric oxygen. Coal oxidation is an irreversible exothermic reaction and its rate increases with temperature.

Spontaneous Combustion in Coals - A Panacea

Journal of the Geological Society of India, 2004
Abstract Lower Gondwana coal samples from the Ib-valley, the Talcher coalfield and the Raniganj coalfield were compared with the Tertiary coals of Upper Assam, Nagaland and Arunachal Pradesh by their chemical data in relation to crossing point temperature, petrography and rank.

The Development of Microporous in Coal by Spontaneous Combustion

Advanced Materials Research, 2014
Basing on coal and the oxygen evolving complex theory, the method of study on the spontaneous combustion by analysis the microporous in coal has been established in this article. By the electron microscope, the process of microporous volume changeing with the temperature gradually increased is observed.

Spontaneous combustion and weathering of coal.

1912
That certain coals are liable to spontaneous combustion has been a recognized fact for many years, but the first attempt to explain the phonomenan scientifically appears to have been made about the year 1868 by Dr. M. Richters, a noted chemist. [...]

Spontaneous combustion in beds of coal particles

Symposium (International) on Combustion, 1989
This paper describes a simple experimental technique to determine the ignition temperature of various cylinder-shaped beds (diameter 17–160 mm, height 10–80 mm) of a South African coal and it reports the application of thermal ignition models in interpreting and extrapolating the small scale results.

Spontaneous combustion of coal: a Mössbauer approach

Fuel, 1992
Abstract A 57 Fe Mossbauer spectroscopic study was carried out at 300 K to study the self-combustion of coal. Hyperfine parameters such as isomer shift, quadrupole splitting and the total internal magnetic field of 57 Fe nuclei were used to identify various iron-bearing species during different stages of the process.

Theories on Spontaneous Combustion of Coal

1993
Kömürün kendiliğinden yanması, tüm kömür üreticisi ülkelerin karşılaştığı en önemli sorunlardan biridir. Bu konunun nedenini saptama çalışmaları daha önceki yüzyılda başlamıştır. Bu sorunun nedeni hakkında çeşitli kuramlar ileri sürülmüş olup bu kuramlar şu şekilde sıralanabilir: - pirit kuramı, - bakteri kuramı, - oksidasyon kuramı ve - nem kuramı. Bu

Modelling spontaneous combustion of coal

2006
Spontaneous combustion of coal is an important problem in mining and storage, in terms of both safety and economics. This is because coal reacts with oxygen in the air and an exothermic reaction occurs, even in ambient conditions. The heat of the reaction accumulates and the reaction becomes progressively faster and thermal runaway may take place to ...
