Spontaneous Combustion of Coals and Coal-Shales
International Journal of Mining Science and Technology, 2018 Spontaneous combustion of coal is a well-known phenomena around the globe. Apart from the coal itself, burning coal-shales is becoming a problem in the South African coal mines. Serious incidents of spontaneous combustion have been reported as a result of self-heating of reactive coal-shales. The intrinsic properties and spontaneous combustion tests of

Recycling of coal combustion wastes
Waste Management & Research: The Journal for a Sustainable Circular Economy, 2009The separation of unburned carbon from coal-fired power plant bottom ashes was conducted in order to increase the possibility of the recycling of coal combustion wastes. A two-stage flotation technique was used for this study. In the rougher flotation experiments the amounts of collector, dispersant and frother, pulp density, pH, particle size ...

Combustion characteristics of high ash coal in a pulverized coal combustion
Fuel, 2001Abstract The influences of ash content on pulverized coal combustion characteristics are experimentally and numerically studied under a staged combustion condition. The stage combustion ratio (the ratio of air volume of the staged combustion air to the total air) is 0 or 30%, and the coals tested are the three high ash coals with different ash ...

Development and Validation of a Coal Combustion Model for Pulverised Coal Combustion
2010 14th International Heat Transfer Conference, Volume 3, 2010To fully understand the processes of heat-and-mass transfer on the laboratory-scale and full-scale coal boilers, computer models are needed to develop, which can predict flow fields, heat transfer and the combustion of the coal particles with reasonable accuracy.

Organic emissions in coal combustion in relation to coal structure and combustion temperature
Fuel, 1985Abstract The pulsed combustion of coal has been studied in a small fluidized-bed reactor. The effect of combustion temperature and coal rank on the organic composition of the off-gas was investigated. Results are presented for the combustion of an anthracite, a medium-volatile bituminous coal and a high-volatile bituminous coal at 700, 800 and 900°C.

MODELLING PULVERISED COAL COMBUSTION USING A DETAILED COAL COMBUSTION MODEL
Combustion Science and Technology, 2006ABSTRACT The ability to assess the combustion behaviour of internationally traded coals and accurately predict flame characteristics, stable species concentration, unburned carbon and pollutant emissions is of importance to the power generating industry. Despite recent advances in coal combustion modelling detailed understanding is still lacking on the

A REVIEW OF SPONTANEOUS COMBUSTION OF COALS
Fuel Science and Technology International, 1995ABSTRACT 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.
