Combustion Instability Mitigation

The combustion instability (thermoacoustic instability) of a gas-fired combustor with a low-frequency instability occurring at 100 Hz, was successfully mitigated using DEICON’s passive acoustic radiation based tuned absorber (damping system). Contrary to the more traditional tuned acoustic absorbers (perforated liners, quarter wave tubes, etc.) that are objectionably large at such low frequencies, DEICON’s passive acoustic […]
