Around of one of ãðàäèðåí THERMAL POWER STATION - 23 of Open Society " Mosenergo " it is established øóìîïîãëîùàþùèé the screen. Developers of the project managed to introduce a number (line) of unique decisions that has allowed to lower considerably øóìîâîå influence from work ãðàäèðíè on the nearest houses.
The THERMAL POWER STATION - 23, located in residential area of East administrative district of Moscow, belongs to number of the most powerful òåïëîýëåêòðîöåíòðàëåé capitals - the established capacity of power station exceeds 1410 ÌÂò. Thus the apartment houses located along the street of Nikolay Himushina, are on distance less than 150 m from border of an industrial platform of the enterprise. Therefore to increase of ecological parameters of work of thermal power station pays the most steadfast attention. One of the major directions of nature protection activity of THERMAL POWER STATION - 23 is decrease(reduction) øóìîâîãî influences on a vein sector. " The station has very big capacity and thus is located in a city boundaries, - director of THERMAL POWER STATION - 23 of Open Society " Mosenergo " marks Nikolay Zrojchikov. - Therefore the problem of a noise isolation for us more than is actual ".
Scientific research institute of Building physics full acoustic inspection of territory of THERMAL POWER STATION - 23 has been lead(has been carried out). During inspection the source of the greatest noise has been revealed - he(it) appeared one of ãðàäèðåí stations (the big concrete construction as the truncated cone, intended for cooling water). The decision on installation on THERMAL POWER STATION - 23 øóìîïîãëîùàþùåãî the screen which would interfere with distribution to an atmosphere proceeding from ãðàäèðíè sound waves was accepted.
The calculations of the acoustic efficiency which has been lead(which has been carried out) by experts of the Moscow Power Institute (Technical University), have shown, that decrease(reduction) in noise on distance from ãðàäèðíè makes of 3 m up to 29 äÁ. Differently, effect from øóìîïîãëîùàþùåãî the screen so big, what even in immediate proximity from ãðàäèðíè practically is not audible any noise. Thus, the level øóìîâîãî influences from work ãðàäèðíè on the nearest houses not only corresponds(meets), but also is much lower than the accepted sanitary norms.
One more conclusive advantage of the given project is his(its) low cost. The initial sum of expenses for installation of the screen exceeded 3,5 million roubles. However after processing the documentation by design group of THERMAL POWER STATION - 23 and introduction of unique decisions it was possible to lower cost of the project to 500 thousand roubles. |
