Development of silencers for suppressing noise emitted from heat-recovery boilers taking into account the attenuation of sound energy in their heating surfaces

Abstract

A formula is proposed using which attenuation of the level of acoustic power in a heat-recovery boiler can be calculated as a function of the area of its heat-transfer heating surfaces. The silencers developed by specialists of the Moscow Power Engineering Institute for additional suppression of noise emitted from combined-cycle and gas turbine units equipped with heat-recovery boilers are considered.
