Fundamental study of coal combustion mechanism in O{sub}2/recycled flue gas combustion process

摘要

Pulverized coal combustion with oxygen and the recycled flue gas is a promising system to recover carbon dioxide from the exhaust gas of boilers for reducing the emission of carbon dioxide to the atmosphere. To develop this type of new coal combustion system, experiments are in progress not only using bench scale pulverized coal burners, but also using microgravity conditions to elucidate the fundamental mechanism of coal combustion. Studies on the flame propagation mechanism of pulverized coal clouds are introduced, which are important for the flame stability in pulverized coal burners.
