ABSTRACT
Many types of devices are used for incineration. The most obvious are incinerators, which are furnaces especially designed and built to burn wastes. However, wastes, especially hazardous wastes, are also burned in boilers and industrial furnaces, mainly cement and aggregate kilns. Approximately 50% of the incinerable hazardous wastes produced in the United States in 1993 were burnt in cement kilns. Irrespective of the type of furnace used, as soon as it burns wastes, it becomes subject to all appropriate laws and regulations that govern the handling, storage, and combustion of wastes.
