Pulse Combustion System (Cello Pulse Burner)
Sonotech's Pulse Combustion System, which includes the patented Cello® Pulse Burner technology, incorporates a combustor that can be tuned to induce large amplitude sonic pulsations inside combustion process units. These pulsations increase heat release, mixing, and mass transfer rates in the combustion process, resulting in faster and more complete combustion. The system typically consists of an air/fuel inlet, combustion chamber, and an exhaust section and can be retrofitted to an existing system. The Sonotech Pulse Combustion System was demonstrated on a pilot-scale rotary kiln incineration system (RKS) at the EPA Incineration Research Facility, Jefferson, Arkansas. The primary objective of the SITE Demonstration was to develop test data to evaluate the Sonotech pulse combustion system's treatment efficiency compared to conventional combustion. Test data were evaluated to determine if the Sonotech pulse combustion system (1) increased incineration capacity, (2) increased destruction and removal efficiency (DRE) of principal organic hazardous constituents (POHC), (3) decreased flue gas carbon monoxide emissions, (4) decreased flue gas nitrogen oxides emissions, (5) decreased flue gas soot emissions, (6) decreased combustion air requirements, and (7) decreased auxiliary fuel requirements. The demonstration revealed that, compared to conventional combustion, the Sonotech system reduced combustion air requirements, as well as overall emissions of carbon monoxide, nitrogen oxides, and soot. The Sonotech Pulse Combustion System also increased the incineration waste feedrate capacity by 13 to 21 percent compared to conventional combustion. The developers claim that this technology can be used to incinerate pesticides, polychlorinated biphenyls (PCB), dioxins, and furans and can be applied to processes such as drying, calcining, and heating.
