Effects of coal oxygen-enriched combustion on energy saving and environment

This article analyses energy saving effects and environment influence of coal oxygen-enriched combustion. Oxygen-enriched combustion can remarkably reduce the amount of combustion air and produced fume. It is also beneficial to reduce and control SO₂ and CO₂ emission, but it can observably increase NO_x emission. For high-sulfur coal, the technology and measure to control SO₂, NO_x and CO₂ emission in oxygen-enriched combustion mainly consider fume separation and recycling and for low sulfur coal mainly consider desulfurization and denitrification in the furnace, fume separation and CO₂ recycling.
