Sealed flask test for evaluating the self-heating tendencies of coals. [Yael Miron; Alex C Smith; Charles P Lazzara; United States. Bureau of Mines.] In addition, a good correlation was obtained between the minimum sht's and pressure changes in the flasks at the end of the test for the same coals, also independent of particle size.

Based on these results, the sealed flask test can be reliably used to determine the self-heating tendency of a bituminous coal Download PDF: Sorry, we are unable to provide the full text but you may find it at the following location(s): (external link) http   The relative self-heating tendencies of 24 coal samples were evaluated in an adiabatic heating oven.

The current methods to evaluate the propensity of coal spontaneous combustion, such as chromatographic method of oxygen adsorption, oxidation kinetics method and activation energy method, are mostly affected by human factors.

Their boundaries among different A rapid method for determining the R 70 self-heating This study developed a rapid method to determine the R 70 self-heating rate of coal. An evaluation method was also proposed to classify the propensity of coal to spontaneous combustion based on this rapid method.
