HarbisonWalker International (HWI) maintains one of the most complete portfolios of refractory products for vessel applications in the incineration industry. Our line includes the KORUNDAL® and TUFLINE® series of high-alumina brick and the RUBY® and AUREX® series of alumina-chrome brick. We also supply the NOVACON® family of products for areas requiring a no-cement monolithic solution. These established, high-end refractory brands are the gold standard for even the harshest incinerator system environments.

Our dedicated incineration application specialists work alongside each customer to evaluate temperature, feed chemistry, thermal shock, mechanical stress, thermal conductivity, and installation restrictions to provide the most compatible lining system for every project.

We continue to consult with our customers over the life of the vessel to address changing burn materials and increased volatility in the feed stream. These services allow us to identify ways to maximize refractory resistance, saving time and money.

No matter what our customers burn, from municipal and corrosive waste to hazardous-waste incineration, they can rely on us to respond quickly and reliably.
