Oxygen-enriched combustion technology application and economical forecast in cement industry kiln
Using combustion theory to research on the technical theoretical features of oxygen-enriched combustion technology application to the cement industry kiln.On the basis of this,engineering projects of that,a certain enterprise 3000 t/d cement clinker production line applied oxygen-enriched combustion technology,and its economic evaluation were calculated.The results showed that:applying Oxygen-enriched combustion technology to the existing cement clinker calcined equipments,the coal powder consumption,the volume of flue gas and CO2 concentration in the flue gas of unit cement clinker occurred regular changes,When the O2 concentration increased from 21% to 30%,the coal powder consumption decreased by 17.78%,the flue gas volume was reduced by 12.73% and the CO2 concentration in the flue gas increased to 76.57%.If the enterprise used the oxygen-enriched atmosphere of O2 concentration for 30% to form the coal combustion,it can save coal about 71.87 t/d,equipment production capacity increase by 41.75% and capture CO2 products about 2662 t.Every year,this resulted in the profit increasing 103 million yuan.
