Spontaneous Combustion of Coal (III)
Fire Science and Technology, 1986 The isothermal thermogravimetric analysis of coal has been carried out by changing the oxygen concentration of the heating atmosphere at the temperature range of 400, 450, 500 and 600°C. The effect of oxygen concentrations of 1 - 50% of the flow gas is discussed based on the weight loss curves and the IR spectra.
