Operation of boilers is connected with the possibility of steam exhaust during blow-offs of boiler super-heaters, boiler kindling, popping of main pressure safety valves and super-heater safety valves, etc. Boiler steam exhaust to the atmosphere is the source of the most intensive noise impact of thermal power plants on the environment. For example, when steam is exhausted sound level increases at 30…40 dbA within a distance of several kilometers.
