The smoke chamber is a critical area, where build-ups, frequent use of high pressure water pump which causes thermal shock make it necessary to use special refractories.
The nose ring is also a critical area, requiring special monolithic refractory material which has an excellent resistance to:
- High Thermal Shock
- Mechanical Resistance
- Chemical Attack Resistance
Our Seven Cast AS 30 has been developed by our R&D department to ensure the best performance for this critical area along with a very fast installation time.
For the tertiary air duct we suggest abrasion resistant castables for the most stressed areas. For the other areas we suggest to use fireclay bricks.
