TL;DR: In this paper, the effect of enhanced oxygen levels and CO 2 bath gas is independently analyzed for their influence on single-particle pulverized coal ignition of a U.S. eastern bituminous coal.
Abstract: Oxygen/carbon dioxide recycle coal combustion is actively being investigated because of its potential to facilitate CO 2 sequestration and to achieve emission reductions. In the work reported here, the effect of enhanced oxygen levels and CO 2 bath gas is independently analyzed for their influence on single-particle pulverized coal ignition of a U.S. eastern bituminous coal. The experiments show that the presence of CO 2 and a lower O 2 concentration increase the ignition delay time but have no measurable effect on the time required to complete volatile combustion, once initiated. For the ignition process observed in the experiments, the CO 2 results are explained by its higher molar specific heat and the O 2 results are explained by the effect of O 2 concentration on the local mixture reactivity. Particle ignition and devolatilization properties in a mixture of 30% O 2 in CO 2 are very similar to those in air.
