Shirco Infrared Systems, Inc., 1195 Empire Central, Dallas, TX 75247-4301

The Shirco Portable Unit was built in response to the increasing interest in on-site thermal treatment of waste and successfully demonstrated thermal destruction of dioxin in soil at Times Beach, Mo. The Portable Unit consists of a feed system, a primary chamber fired with electric infrared heating elements, a gas-fired secondary chamber, a wet gas scrubber, monitoring and control systems, and heating element power centers. All equipment is enclosed in a 45 foot trailer. Material is conveyed through the incinerator in a thin sheet on a wire mesh belt, giving all material the same residence time under controlled process conditions. One of the on-site tests performed by the Unit was the thermal destruction of dioxin at Times Beach, Mo. No dioxin was detected in the treated soil, flue gases, or scrubber effluent. The resulting Destruction and Removal Efficiencies (DRE) were greater than 99.9999 % and the particulate emissions were well below 0.08 gr/dscf required by RCRA.

The difficulty of transporting hazardous material to Shirco*s Test Facilities in Dallas, Texas, was increased significantly by the implementation of RCRA Regulations. A substantial need existed for a trailer-mounted system which could be moved to waste producing and waste storage sites for thermal treatment testing. Past experience indicated that the ceramic fiber insulated, infrared incinerator was much easier to transport than other similar equipment and was uniquely suited for this type of portable application. In response to this need, Shirco designed and built the Portable Unit to demonstrate the capabil i t i e s of a portable infrared incinerator at waste sites.
