Abstract
This paper presents a discussion of the various chemical and physical forms of metal compounds that may be used for spiking during the trial burn or compliance test for hazardous waste combustion systems. It discusses the factors which should be considered in selecting the forms of the spiking metals for organic (hot, high Btu, or high heating value) waste streams, aqueous waste streams, and solid waste streams. The paper focuses on the organic waste streams and compares the use of organic metal dispersion to the use of organometal compounds or aqueous solutions of metal compounds as spikes for these types of feed streams. It is concluded that metal dispersions appear to form particulate which is in the appropriate micron range to tax the air pollution control system's performance. Dispersions of all regulated metals are commercially available in the required quantities for each application and they are relatively easy to pump, and to meter. Dispersions can be formulated so that their heating values are high enough to maintain the required elevated combustion and flame temperatures, and they are representative of the most common types of metal-bearing wastes sent to incinerators. The dispersions can also be used to spike metal compounds into water-based waste streams.
