 — The pozzolan activation line has a countercurrent rotary kiln of Ø3.0 m × L = 52 m. The calcined clay was cooled by a rotary cooler (that also preheats the combustion air), and the de-dusting was done by high efficiency cyclones and a baghouse filter. The combustion system is a D-Gasifier that burns grinded petroleum coke.

 — The simulation results show that the gasifier can completely remove NO x from the rotary kiln at 2.8 kg/s for coal, 30 kg/s for raw meal and 2.5 kg/s for tertiary air. The application results show that under 1.6 kg/ t.cl of ammonia water combined with SNCR, NO x emission and ammonia slip can be controlled below 50 mg/Nm 3 and 5 mg/Nm 3 ...
