Abstract

The 150 tpd facilities of sewage sludge pump directly into precalciners was set up in cement plant of 3200 tpd clinker production. The experiment was performed at the sludge feed rate of 4t/h, 6t/h and without sludge. It was showed from that the use of sludge as alternative fuel did not affect clinker quality negatively. The initial and final setting times of cement clinker were longer than when sludge was not co-disposed, but they remain within the standard range. With the increase of sludge volume from coal consumption increased, the yield decreased. Sludge as an alternative fuel, not only can reduce ammonia consumption and to help reduce nitrogen oxide emissions. Finally, the run data find that if the moisture content of the sludge to reduce, the volume of sludge can increase.
