Silencing system is used for noise control and air filtration solutions for gas-fired turbines and combustion engines that are used for stationary and portable power generation applications. Gas turbines produce hot gases up to 1200 ºF, in swirl flow with non-uniform velocities and pressures. High thermal stresses, pressure variances occur and high levels of noise and vibration are generated. Thus silencers are used in this hostile environment to reduce noise emissions and ensure both worker safety and regulatory compliance.
A gas turbine is a rotary engine that extracts energy from a flow of hot gas produced by combustion of gas or fuel oil in a stream of compressed air. It has an upstream air compressor (radial or axial flow) mechanically coupled to a downstream turbine and a combustion chamber in between. Gas turbine is described thermodynamically by the Brayton cycle, in which air is compressed isentropically, combustion occurs at constant pressure, and expansion over the turbine occurs isentropically back to the starting pressure.
