The boiler ash chamber is a critical component of the boiler system, subjected to high temperatures, ash erosion, and frequent thermal cycles. Therefore, it demands high strength, wear resistance, and thermal stability from refractory materials. Using feuerfeste Gusserzeugnisse for solid brick forming is a mature and efficient method for ash chamber lining structures.
Refractory castables are produced by casting in molds, vibration molding, and curing/sintering to create high-strength solid bricks. Compared to traditional clay bricks, these bricks have higher density and better integrity, effectively resisting ash erosion and mechanical wear during boiler operation. Furthermore, their excellent high-temperature resistance allows for long-term stable operation in the high-temperature ash chamber environment, reducing structural cracking and spalling.
In boiler ash chamber applications, castable solid bricks typically possess high compressive strength and thermal shock resistance, making them suitable for critical components such as ash hoppers, ash discharge ports, and ash channels. Prefabrication not only improves construction efficiency but also ensures uniform brick dimensions, reducing on-site construction errors and thus extending the overall service life of the lining.
In conclusion, the application of solid refractory castable bricks in boiler ash chambers combines wear resistance, heat resistance, and ease of construction, making it an ideal choice for modern boiler ash chamber refractory linings.
