Spontaneous Combustion of Coal (I)
Thermogravimetry of coal has been carried out by changing the oxygen concentration of the heating atmosphere, and the effect of oxygen in the concentration of 1-60% flow gas has been discussed based on the thermogravimetric curves. The kinetic parameters of exothermic oxidizing reaction of coal in the thermogravimetric, which has one of the critical ...

Estimation of greenhouse gas emissions from spontaneous combustion/fire of coal in opencast mines – Indian context [PDF]
There are a significant number of uncontrolled coal mine fires (primarily due to spontaneous combustion of coal), which are currently burning all over the world. These spontaneous combustion sources emit greenhouse gases (GHGs). A critical review reveals

Combustion behaviour of some biodesulphurized coals assessed by TGA/DTA [PDF]
Thermal analysis, i.e. TGA/DTA is used to study the changes in the combustion behaviour of microbially treated coals. In view of their high sulphur content and industrial significance three samples are under consideration, i.e.

Comparative analysis of coal and coal-shale intrinsic factors affecting spontaneous combustion
Coal and coal-shales tend to undergo spontaneous combustion under favourable atmospheric conditions. Spontaneous combustion liability index and intrinsic properties of coals and coal-shales varies between (above and below) coal seams.
