Noise and vibration protection of roof boiler equipped house

The roof mounted boiler house is one of the perspective kinds of autonomous heat supply. Boiler houses are located on the building roofs or on a special substructure, mounted over the roof. New apartment blocks are usually equipped with the roof mounted boiler houses thanks to the high cost effectiveness of this solution. However, vibration isolation is often neglected when boilers are installed directly to the substructure. As a result, residents of the upper floor apartments  suffer from the constant noise exposure. Experimental studies of various boiler equipment operation modes were conducted in order to determine the main sources of noise and their frequency spectrum. It was shown that the main source of the noise increase in residential areas was the boiler combustion process. The noise has a structural character. The  vibration protection system, based on the rope isolators (VMT), has been developed in order to reduce the noise levels in residential areas. We have carried out necessary calculations, taking into account the weight of the boiler, the water in it and all associated elements. Also, the isolator samples were a statically tested. The vibration protection system implementation provides the achievement of sanitary noise norms in residential areas.
