• CO and CO2 Emissions from Spontaneous Heating of Coal Under Different Ventilation Rates
  10/1/2011 - Peer reviewed journal articles
  This study evaluated CO and CO2 emissions from spontaneous heating of a U.S. coal sample in an isothermal oven under different airflow ventilation rates from 100 to 500 cm3/min. Experiments were conducted at oven temperatures of 70, 90, and 100 °C.
