燃氣發(fā)電機組運行時，通常會產(chǎn)生95～128db（a）的噪聲。如果不采取必要的降噪措施，機組運行的噪聲將對周圍環(huán)境造成嚴重損害。為了保護和改善環(huán)境質(zhì)量，必須對噪聲進行控制。

When the gas-fired generator set is running, it usually produces 95 ~ 128dB (a) noise. If necessary noise reduction measures are not taken, the noise of unit operation will cause serious damage to the surrounding environment. In order to protect and improve environmental quality, noise must be controlled.

燃氣發(fā)電機組的主要噪聲源均為燃氣機產(chǎn)生，包括排氣噪聲、機械噪聲和燃燒噪聲、冷卻風扇和排風噪聲、進風噪聲、發(fā)電機噪聲、地基振動的傳遞所產(chǎn)生的噪聲等：

The main noise sources of the gas-fired generator set are all generated by the gas turbine, including exhaust noise, mechanical noise, combustion noise, cooling fan and exhaust noise, air inlet noise, generator noise, noise generated by the transmission of foundation vibration, etc

排氣噪聲。排氣噪聲是一種高溫、高速的脈動性氣流噪聲，是發(fā)動機噪聲中能量的一種，其噪聲可達100db以上，是發(fā)動機總噪聲中主要的組成部分。

Exhaust noise. Exhaust noise is a kind of high-temperature, high-speed pulsating air flow noise, which is one of the energy in engine noise. Its noise can reach more than 100dB, and it is the main component of the total engine noise.

發(fā)電機工作時產(chǎn)生的排氣噪聲通過簡易排氣管（發(fā)電機組原配排氣管）直接排出，并且隨氣流速度增加，噪聲頻率也顯著提高，這樣對鄰近居民的生活，工作造成嚴重的影響。

The exhaust noise generated during the operation of the generator is directly discharged through a simple exhaust pipe (the original exhaust pipe of the generator set), and the noise frequency is significantly increased with the increase of air flow speed, which has a serious impact on the lives and work of nearby residents.

機械噪聲和燃燒噪聲。機械噪聲主要是發(fā)動機各運動部件在運轉(zhuǎn)過程中受氣體壓力和運動慣性力的周期變化所引起的震動或相互沖擊而產(chǎn)生的。它具有噪聲傳播遠、衰減少的特點。燃燒噪聲是燃氣在燃燒過程中產(chǎn)生的結(jié)構(gòu)震動和噪聲。

Mechanical noise and combustion noise. The mechanical noise is mainly caused by the vibration or mutual impact of the moving parts of the engine caused by the periodic changes of the gas pressure and the moving inertia force. It has the characteristics of long noise propagation and reduced attenuation. Combustion noise is the structural vibration and noise produced by gas during combustion.

冷卻風扇和排風噪聲。機組風扇噪聲是由渦流噪聲、旋轉(zhuǎn)噪聲以及機械噪聲組成。排風噪聲、氣流噪聲、風扇噪聲、機械噪聲會通過排風的通道傳播出去，從而對環(huán)境造成噪聲污染。

Cooling fan and exhaust noise. The fan noise of the unit is composed of eddy current noise, rotating noise and mechanical noise. Exhaust noise, air flow noise, fan noise and mechanical noise will be transmitted through the exhaust channel, resulting in noise pollution to the environment.
