Graphite Block Seal
Sealing off a rotary kiln process from false or in leaked air is vital to maximizing process reliability and availability.
Graphite seal an effective, economical and easy-to-install solution for retrofitting to any make of rotary kiln – with no modifications needed at the inlet or outlet.
Graphite seal brings clear operational benefits. By preventing cool false air (ambient temperature) reaching the hot process gas (ca. 1300 °C.), it improves the stability of the clinker production process by ensuring a more constant temperature inside the kiln. At the same time, minimizing the amount of false air entering the kiln results in energy savings of an operationally significant magnitude. The amount of energy required per kg of clinker is greatly reduced. The less energy is consumed, the lower the CO2 emissions.
Air problem
An effective sealing solution must seal off the kiln process from false or in leaked air. False air at the kiln inlet has a negative effect on the chemical process. In leaked air at the kiln outlet increases the energy required for the clinkering zone burner
Fast, easy installation
To reduce downtime during installation, the kiln graphite seal is
designed with a modular frame that allows for a large amount of preassembly. To ensure optimal quality and the straightness of the flanges, graphite seals are preassembled in the workshop to ensure the straightness of flanges.
Retrofitting kiln seals
The kiln graphite seal is highly flexible in design and easily adaptable to any size of kiln
Predictable maintenance
Maintenance of the kiln graphite seal is easy to predict by simple visual inspection. When needed, the wire rope system and modular frame allow for secure and fast replacement of the graphite blocks.
