16 <br /> The Principle of Air Curtain Incineration <br /> OPERATION <br /> The operating principle of the air curtain within an incineration device lies in the <br /> introduction of controlled high velocity air across the upper portion of the combustion <br /> chamber in which combustibles, such as wood, are loaded. The powerful curtain of air <br /> created in this process is actually a rotating mass of high temperature air (2,300° F or <br /> 1,260° C, or more) that has been trapped in the chamber. The increased combustion <br /> time and turbulence results in complete combustion of the loaded waste and the <br /> protective curtain created by the rotating air significantly reduces emissions. <br /> This effective and essentially clean incineration of wood waste is documented in <br /> engineering studies and analyses that have been compiled over the years at operating <br /> facilities throughout the US. <br /> 1 Air Burners <br /> 4 <br /> 4- 2 <br /> �r <br /> 3 <br /> 1. Air curtain machine manifold and nozzles directing high velocity air flow into <br /> refractory lined box or earthen trench. <br /> 2. Refractory lined wall as on the S-Series machines, or earthen wall as used with <br /> the T-Series machines. <br /> 3. Material to be burned. <br /> 4. Initial airflow forms a high velocity "curtain" over fire. <br /> 5. Continued airflow over-oxygenates fire keeping temperatures high. Higher <br /> temperatures provide a cleaner and more complete burn. <br />
