Description:
Oxygen enriched coal (oxy-coal) combustion is a developing technology. During oxy-coal combustion, combustion air is separated and the coal is burned in a mixture of oxygen and recycled flue gas. The resulting effluent must be further processed before the C02 can be compressed, transported, and sequestered. Many operational and environmental issues must be addressed before oxy-coal combustion can be adopted commercially. These include effects on pollutant formation, performance of existing pollutant control devices, required purity of the process gas for C02 compression, and partitioning of pollutant species between various effluent streams. This presentation will report the results of initial ash vaporization experiments using a 2 g/min drop tube furnace, as well as the status of the design and modification of a 150,000 Btu/hr laboratory-scale furnace for oxy-coal operation.
