Experimental study on inhibition of coal spontaneous combustion by carbon dioxide and nitrogen

Energy Sources, Part A: Recovery, Utilization, and Environmental Effects
Injecting CO2 and N2 to reduce the concentration of O2 in the air is a commonly used measure to prevent coal spontaneous combustion (CSC). To study the difference in inhibitory effects of CO2 and N2 on coal oxidation, experiments in this study were ...

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.

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.
