Coal oxidation at low temperatures is the heat source liable for the self-heating and
spontaneous combustion of coal. This phenomenon has imposed severe problems in coal …

Coal oxidation at low temperatures (ie< 100° C) is the major heat source responsible for the
self-heating and spontaneous combustion of coal and is an important source of greenhouse …

Abstract Methane (CH 4), a key gaseous product of coal–oxygen reactions that severely
pollutes the atmosphere and is therefore a health hazard. The microcharacteristics of CH 4 …

Large-scale experiments could reflect the real status of coal spontaneous combustion and
therefore were conducted to investigate the characteristics of coal oxidation during the …

A computational fluid dynamics (CFD) study was conducted to model effects of coal
properties on the potential for spontaneous heating in longwall gob (mined-out) areas. A two …

This study evaluated the spontaneous combustion characteristics of Askale lignite from
Turkey. The effect of the gas flow rate, the moisture of the piles of coal, the humidity of the air …

Self-heating or even spontaneous combustion of stockpiled coal, which is likely to outbreak
under favourable circumstances during its transport, process, and storage, is a long …

Spontaneous combustion period is an important characteristic parameter of coal
spontaneous combustion. It must be understood to prevent and control coal fire disasters in …

A commercial CFD software programme, FLUENT, was used to study the oxidation process
of coal in the mined-out longwall (gob) area. A three-dimensional, single-phase model with …

The results of an experimental study aimed at evaluating the spontaneous combustion
characteristics of two Turkish lignites moistured and air-dried at varying times are discussed …
