燃气bat365官方网站登录组运行时，通常会产生95～128db（a）的噪声。如果不采取必要的降噪措施，机组运行的噪声将对周围环境造成严重损害。为了保护和改善环境质量，必须对噪声进行控制。

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.

燃气bat365官方网站登录组的主要噪声源均为燃气机产生，包括排气噪声、机械噪声和燃烧噪声、冷却风扇和排风噪声、进风噪声、bat365官方网站登录噪声、地基振动的传递所产生的噪声等：

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

排气噪声。排气噪声是一种高温、高速的脉动性气流噪声，是发动机噪声中能量的一种，其噪声可达100db以上，是发动机总噪声中主要的组成部分。

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.

bat365官方网站登录工作时产生的排气噪声通过简易排气管（bat365官方网站登录组原配排气管）直接排出，并且随气流速度增加，噪声频率也显着提高，这样对邻近居民的生活，工作造成严重的影响。

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.

机械噪声和燃烧噪声。机械噪声主要是发动机各运动部件在运转过程中受气体压力和运动惯性力的周期变化所引起的震动或相互冲击而产生的。它具有噪声传播远、衰减少的特点。燃烧噪声是燃气在燃烧过程中产生的结构震动和噪声。

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.

冷却风扇和排风噪声。机组风扇噪声是由涡流噪声、旋转噪声以及机械噪声组成。排风噪声、气流噪声、风扇噪声、机械噪声会通过排风的通道传播出去，从而对环境造成噪声污染。

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.
