燃气轮机单管燃烧室试验台消声器

A silencer for the single can-type combustion chamber test bed of a gas turbine

本消声器较好地解决了燃气枪机单管燃烧室试验(具有高温1000℃、高压6kg/cm^2、高噪声123dB(A)的特点)的消声问题,其降嗓量为55dB(A)。同时亦解决了烟气分析采样的技术问题。

The noise attenuation relating to the testing of a gas turbine single can-type combustion chamber (high gas temperature of 1000℃, high pressure of 6 kg/cm^2 and high noise level of 123 dB(A) has been successfully attained by a silencer proposed by the author. The noise reduction has been estim- ated at 55 dB (A). In addit on, the technical problem of exhaust gas sam- pling for analysis has also been solved.
