摘要：

Some coals are susceptible to spontaneous combustion. In this paper, crossing-point temperature (CPT) and critical self-ignition temperature (CSIT) analyses as critical self-heating methods and low-temperature oxidation (LTO) analysis as an isothermal oxidation method were used to determine the spontaneous combustion characteristics of Indonesian low-rank coal with different particle sizes. In the CPT and CSIT analyses, larger particles were found to have a low risk of spontaneous combustion along with an increasing particle size in coal. Meanwhile, in LTO analysis, the dependency on particle size was only found in smaller particles rather than larger ones. © 2019 Taylor & Francis Group, LLC.
