Increasing safety of thermal and nuclear power stations energy equipment by reducing noise

Noise is the most important factor of physical effects at normal operation thermal and nuclear power equipment. Increasing the safety of the power equipment of thermal power (TPS) and nuclear power stations (NPS) is important task. This task is also associated with a decreasing the noise from power equipment. The problem of noise reduction by thermal and nuclear power equipment in the surrounding areas is discussed. Here are the original theoretical developments of the education of the most intense noise sources. There is also given and original examples of devices to reduce noise from them: from steam emissions, draft machines, cooling towers, etc. Creating mathematical models of thermal or nuclear power plants allows us to consider the effect of the limiting factors in the development of the noise safety from TPP and NPS. Mathematical models allow us to study the effects of sound power sources and its amount, location of sources at the site, the mode of operation of the equipment, index of their direction, the orientation of the power equipment and other factors on the noise levels in the surrounding area. The results of the original tests various silencers and acoustic barriers are given. The importance of complex noise reduction on the totality of sources of noise to ensure noise sanitary standards in the surrounding area are shown.
