摘要
针对控制和降低环境噪音的要求,分析了9FA燃气轮机进气集流室产生噪音的原因,并对其消音结构进行了改进,通过试验测试得出,进气集流室噪音等级满足了设计要求。
In order to control and reduce the noise produced by inlet collecting chamber of 9FA gas turbines, structural retrofit was made to its silencer by analyzing the noise causes. Experimental results show that the noise level in the inlet collecting chamber can then meet design requirements after corresponding structural retrofit made.
