A METHOD FOR JUSTIFICATION OF THE MEASURES TO REDUCE THE NOISE FROM THE GAS PIPELINES OF A GAS-DISTRIBUTION STATION

摘要

Power facilities near residential areas in modern cities are the major cause of violation of the sanitary standards. One of the noise sources at thermal power plants is the gas pipelines of gas distribution stations. The crucial problem is that the noise level can be exceeded by several tens of decibels where the gas pipeline exits the gas distribution building, as well as along the entire gas pipeline. To reduce noise from a gas pipeline, it is possible to use acoustic insulation of gas pipelines and noise barriers. It is shown that only the combinatin of acoustic insulation and noise barriers can ensure the necessary noise reduction. A new method of feasibility analysis is proposed that allows developing measures for reducing the noise from the gas pipelines of gas distribution stations to the sanitary limits at the lowest cost by combining noise barriers and acoustic insulation.
