Attachment B is a technical specification document for an Air Curtain Combustor (ACC) related to the Disaster Debris Collection and Removal contract for Pinellas County, Florida, covering the period 2025-2030. The document provides a detailed schematic and explanation of the air curtain combustion technology, which is designed to safely and efficiently burn debris during disaster recovery operations. The air curtain system utilizes a power source (electric motor or diesel power unit) to drive a fan that creates a high-velocity air curtain across a pit, trapping smoke and small particles to enhance combustion and reduce smoke emissions.

The technical specification details both above-grade and below-grade configurations of the air curtain combustor, highlighting its operational characteristics, including the ability to generate pit temperatures between 1800 and 2200 degrees Fahrenheit. The system includes key components such as a fan blower, plenum, nozzle, and a pit with an impervious layer, designed to provide a safe combustion chamber that minimizes heat loss. The diagrams illustrate the precise arrangement of components, including specifications for compacted limestone fill, dirt seal, and the overall dimensional layout of the combustion system, which is critical for efficient debris management during disaster recovery efforts.
