Overview

Experimental analysis reveals how gas dynamics influence coal oxidation and combustion risk, suggesting improved monitoring methods.

Key Points

  • The study aims to understand how fluctuating oxygen levels and gas production affect coal oxidation and combustion risks.
  • Developed a dual coal sample tank experimental system.
  • Conducted experiments under controlled thermal conditions.
  • Measured coal oxidation indicators like O2 consumption and CO/CO2 generation.
  • Benchmarked results against fixed-O2 reference conditions.
  • Dynamic atmospheres lead to reduced oxygen consumption and heat release rates.
  • CO and CO2 actively change reaction kinetics, promoting CO yield even at lower temperatures.
  • Conventional risk assessments based solely on temperature are inadequate for hazard detection.
