Grate kiln system liming Outotec

The grate chain travels flat and straight. The grate travels through a furnace with several zones that expose the pellets to different temperatures. Once the pellets are discharged into the kiln, the grate chain returns underneath. The grate is driven by a motor with gearbox or hydraulic drive. The grate is supported by rollers. Rotary kiln

CONTRIBUTIONS TO THE TECHNOLOGY COMPARISON

Comparing both technologies, the bed height in the straight grate technology is higher. The straight grate technology requires the use of hearth layer, which ranges between 6 and 10cm in height, whereas the green pellet height is typically between 30 to 45cm. In the grate-kiln system, the bed height is 12 to 23 cm on the preheat

kiln efficiencies FCT Combustion

With a scientific history of 30 years in rotary kilns and 10 years in traveling straight grate pelletizing plants, FCT has well proven that the burner design cannot be satisfactory unless furnace design (geometry, aerodynamics), operation philosophy and all other relevant parameters have been considered accordingly. In many cases, feedback
