A comparative analysis of lightweight aggregate and cement kilns operated under the Boiler and Industrial Furnace Rule
- Solite Corp., Richmond, VA (United States)
Eighteen lightweight aggregate (LWA) kilns at five locations currently have interim status under the BIF Rule. Two additional LWA kilns at a sixth location are burning hazardous waste fuel under an incinerator permit. Although these units comprise a significant fraction of the existing and potential commercial BIF capacity in the Eastern United States, relatively little technical literature has been generated regarding the burning of hazardous waste in LWA kilns, and both regulators and the public tend to view LWA kilns as a variant of cement kilns. However, along with similarities, there are a number of important differences between these two categories of industrial furnaces. Among the more significant are differences in typical kiln size, raw feed, operating conditions and uses of kiln dust. This paper is a comparative analysis of cement and lightweight aggregate kilns operating under BIF. It addresses design features, raw material and fuel emissions, products and residuals. Both technical and legal/regulatory of differences are analyzed. Finally, the potential impact of EPA`s Waste Combustion Strategy upon LWA kilns is evaluated.
