Ammonia-free Denitration Kiln Tail Sintering System

Ammonia-free Denitration Kiln Tail Sintering System technical transformation can reduce the ammonia water consumption by more than 60%. The NOx emission can be dramatically reduced to become environment compliant while minimize use of ammonium,urea and catalyst.

Technical Principle of Ammonia-free Denitration Kiln Tail Sintering System

1 High-strength reduction denitration of decomposing furnace 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.

2 Optimized control of coal used at kiln head and taill 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; while increasing the coal consumption ratio of decomposing furnace.

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%
