Technical Principle of Ammonia-free Denitration Kiln Tail Sintering System

1 High-strength reduction denitration of decomposing furnace

HJ ammonia-free denitration kiln tail sintering system is free of air separation and coal separation process. On the one hand, NOx is reduced and extruded during combustion process. On the other hand, the decomposition rate and temperature of the materials fed into the kiln can be increased without crusting thus to develop high-strength reduction combustion control technology of decomposing furnace.     

Optimized control of coal used at kiln head and tail

The ammonia-free denitration kiln tail sintering system adjusts the appropriate head and tail coal consumption ratio by appropriately reducing the coal consumption at the kiln head; in addition to reducing the coal consumption at the kiln head, the coal consumption will be decreased while ensuring normal calcination in the kiln; while increasing the coal consumption ratio of decomposing furnace, ensure no oversintering and no crusting at the preheater decomposing furnace thus to enhance calcination. 

Feactures:

1 ammonium,Urea and catalyst free.

2 Strengthen the calcination

3 Flexible adjustment and control of combustion

4 Adapt to different grade of coal

5 non-overburning

Benefits:

1 Lower NOx emission and Compliance with environmental regulations

2 Reduce ammonia water consumption by more than 60%

3 Reduce coal and power  consumption.
4 high calciner burnout rate, high thermal efficiency, and No oversintering，crusting and Clogging

5 Reduce the production cost of cement clinker and increase the output by 5%-10%
