The Investigation on Application of Oxygen-Enriched Combustion in Cement Rotary Kiln
The investigation on application of oxygen-enriched combustion in cement rotary kiln shows that flame temperature in rotary kiln can be increased, which improves the utilization of coal and thermal efficiency of rotary kiln. And the fuel consumption and the cost of production can be reduced. In this situation, the objective of increasing production, improving quality and saving energy can be achieved. In the meanwhile, the requirement of air can be reduced in oxygen-enriched combustion. Thus the generation of flue gas and the products of incomplete combustion, which usually are CO, can be reduced. And then the exhaust gas loss and the generation and emission of CO2 and NOx can be accordingly reduced, which enhances to achieve the objective of reduction of pollutants and promote the environmental benefit greatly.
