Chemical Processing Whether the chemical plant operating unit is a state-of-the-art coal gasifier, an oil gasifier, a carbon black reactor, an ammonia primary or secondary reformer, a coke calcining rotary kiln, a lightweight aggregate rotary kiln, an alumina rotary kiln, an alumina flash calciner, a waste heat boiler, a renewable energy ethanol or bio-diesel generator, H-W has the heat containment refractory solution. Our worldwide customer base over the last 40 years shows the value H-W can give our clients.  Incineration Incineration of corrosive waste materials has become an increasingly acceptable method of disposal for these materials. Commercially and privately operated incinerators will be a part of the foreseeable future. Conditions relative to refractory longevity vary throughout these units, and zoning of refractory quality is required to achieve long running campaigns and maximize cost effectiveness. Thermal profiles, waste streams, generated slag, and operating practices are individual for each incinerator in operation, and refractory practice is therefore an individual matter.  Power Refractory technology for this industry has changed with the evolution of new demands for power and economic and environmental concerns. A wide variety of materials are available for use in industrial boilers, package boilers, cyclone boilers, waste-to-energy units, CFB’s, ash hoppers and others.  Paper Harbison-Walker responds to the challenges of the modern paper mill by offering a range of highly specialized refractory products for every stage of the paper making process. These products maximize energy utilization, respect environmental considerations and help achieve long-lasting, economical boiler and rotary kiln performance. As always, Harbison-Walker backs its products with the industry’s most experienced and knowledgeable sales and technical staff, along with an extensive network of contractor/installers. Our people help you select the right refractory for a particular application and can also offer suggestions concerning the construction of refractory linings.  Refineries H-W has supplied refractory products for demanding refinery requirements since the 1940's. H-W offers exceptional products to meet current market demands to lower refinery downtime and increase lining service life. Whether the operating unit is a FCCU, sulfur reaction unit, heater, hydrogen furnace, boiler, or coking furnace, H-W has the product to maximize lining life.
