A hazard assessment of an incineration-based process for the destruction of hazardous liquids identified a potential for vapor explosions in the furnace. Such explosions could threaten worker safety and plant equipment integrity. The furnace was designed to decontaminate steel containers after 95% of the liquid waste was drained. Decontamination of aluminum containers was proposed, but the design operating temperature was above the aluminum melting point To ensure preclusion of molten-metal/volatile-liquid contact, finite-difference models were developed to examine the relative timing of waste evaporation and aluminum melting. Radiative, convective and conductive heat transfer effects were included. Parametric variations of the circumferential nodalization, the amount of residual waste, the initial temperature, and the container surface emissivities were analyzed. The aluminum container was predicted to reach its melting point before complete liquid evaporation occurred. Thus, an evaluation of the process will be necessary prior to processing aluminum containers.
