摘要
The invention relates to a method and burner for injecting pulverized coal into a rotary kiln that uses pulverized coal as fuel in order to produce quick lime of excellent hydration level. The invention calcines lime stone charged into the rotary kiln, and uses pulverized coal as fuel of a heat source applied to the lime stone charged in the rotary kiln. The invention also provides a method and apparatus for producing quick lime by using the pulverized coal. The invention can use pulverized fossil fuel (hereinafter will be referred to as pulverized coal), which is created during coke manufacturing and cooling processes and collected by a dust collector, in order to produce quick lime of excellent hydration level while decreasing SOx (sulfide) and NOx (nitride) generation.
