All the headings should be uppercase, bold Arial size 10 font. In order to comprehensively understand the serious disaster of underground mineral self-ignition and source loss in practice, dynamical and thermo-chemical phenomena of coal spontaneous combustion were investigated. A coupled conductive, convective and radiative heat transfer model for inclined outcrop seam in porous coal-bearing st...

Work is focused to the study of unburned carbon in ash from coal (and wastes) combustion in 8 combustion tests at 3 fluidised-bed power station, at co-combustion of coal and wastes (also at fluidized bed) and at bench-scale unit simulating coal combustion in small domestic furnaces. The attention is paid to unburned carbon contents in bottom ashes and fly ashes at these 8 combustion tests and t...

The thermal characteristics and kinetics of coal, biomass (pine sawdust) and their blends were evaluated under combustion conditions using a non-isothermal thermogravimetric method (TGA). Biomass was blended with coal in the range of 5-80 wt.% to evaluate their co-combustion behaviour. No significant interactions were detected between the coal and biomass, since no deviations from their expecte...

To investigate if there is synergistic interaction between bamboo with coal, or between torrefied bamboo with coal during cocombustion, bamboo and torrefied bamboo separately were respectively uniformly mixed with coal and the weight percentage of bamboo or torrefied bamboo in the mixture were 10%, 20%, 30%, and 40%. The combustion behaviors of blends were characterized using thermogravimentric...

Spontaneous combustibility character of the Talcher coals has been measured in terms of peroxy complex and crossing point temperature. Coal samples collected from the two horizons i.e. Karharbari Formation and Barakar Formation were separately studied and the values measured for the aforesaid parameters were recorded. It was found that the coals of this coalfield are highly prone to spontaneous...

Oxy-fuel coal combustion with flue gas re-circulation is known to be one of the most promising methods for reducing CO2 emissions from coal combustion power plants. In the oxy-fuel system, the combustion atmosphere consists of only O2 separated from air and flue gas re-circulated from a stack. Therefore, the flue gas is dominated by CO2 without any nitrogen gas. The most attractive potential as...

In China, coal combustion to generate electric power is the primary method, the energy-saving and emission reduction is the urgent task. At present, the energy-saving dispatching trial method in some area evaluates energy-saving and emission reduction of coal combustion power generation according to power supply coal consumption rate only. But the power supply coal consumption rate can’t reflec...
