Project brief
The regenerator was not merely a space to be filled with refractory shapes. It was a vertical thermal structure whose commercial value depended on heat economy, chemical order, and structural persistence over a long campaign. Checker packing, alkali-bearing vapor, condensation-sensitive intermediate levels, lower support, and backup heat retention were all present, yet the earlier lining discussion had been too general to protect any of them properly. The plant needed a route that respected the regenerator as a system with height, chemistry, and memory.
Equipment and hot zones
- Checker body and primary heat-storage packing
- Intermediate sections exposed to vapor chemistry and condensation-related pressure
- Lower structural and load-bearing zones
- Backup insulation-support areas tied directly to heat economy
Failure pressure profile
- Alkali-bearing vapor and condensation-related chemical attack
- Thermal fatigue over long regenerator campaigns
- Efficiency loss where vertical zoning was weak or oversimplified
- Structural drift when lower support duty was underread
Material combination
- Magnesia checker brick in the main heat-storage body
- Magnesium spinel composite brick in sections where alkali chemistry and condensation risk demanded a higher-discipline route
- Burned magnesia brick in lower structural and load-bearing positions
- Lightweight microporous magnesia brick and related insulation-support logic where heat-retention value justified a lighter backup section
What changed commercially
The regenerator became easier to evaluate as a heat asset rather than a masonry task. Buyers could discuss heat economy, structural order, and campaign life together without drifting into generic furnace language. That gave HANHENG a more credible position in glass service: specific enough to be trusted, commercially useful, and still anchored to the mapped product families already confirmed for this route.
