description: The theme of the final qualifying work: "Project of steam silencers for cooling down steam boilers at Vyborg CHPP-17". The object of the study is the Vyborg CHPP (CHP-17) of the Nevsky branch of PJSC TGC-1. The paper considers the problem of the noise impact of steam discharges from the boilers of the Vyborgskaya CHPP on the nearby residential area. To prevent the noise level from being exceeded, it is proposed to install an efficient silencer to achieve the target noise level characteristics. The aim of the study is to determine the noise level of the steam discharge and to develop silencers to reduce the noise level. In the course of the work, an analysis of the development of the nearby area was carried out, a map of the CHPP area was built within a radius of 2 kilometers with designations of sound pressure levels at different distances from the steam discharge epicenter. Calculations of the target value of sound pressure and target values of the efficiency of noise suppressors were made. As a result, based on the target characteristics, noise suppressors designed by the Barnaul Boiler Plant were selected and the sound pressure levels after implementation were calculated, enlarged economic calculations of the cost of introducing noise suppressors were given. It is recommended that when implementing, consider the mass of silencers and the maximum load that the supporting structures of the roof of the workshop can withstand.
