Description

Journal ArticleRotary kilns have been used extensively in the cement industry to calcine limestone. In the past few years, the technology has been viewed as a possible option for the incineration of hazardous waste materials, especially for the disposal of solid wastes and the cleanup of contaminated soils and transformers.1 The technology is promising for incineration of hazardous waste for several reasons. First, it is flexible,2 i.e., many different types of solids and liquids can be fed into a single facility. Second, in some cases, incineration greatly reduces the volume of solid waste streams. Finally, there are many existing facilities that could be retrofitted for use in hazardous waste incineration. The kiln is used to drive the hazardous compounds into the gas phase, and an afterburner is used to destroy the gaseous compounds by exposing them to the required time/temperature history. Incineration success is measured by the destruction and removal efficiency (DRE), for each toxic
