Stopson Italiana supplied 21 vent silencers for PSV and start-up valves as well as for atmospheric blow-down tank to Agios Nikolaos power plant in Greece
A soundproofing comprehensive installation has been recently delivered to assist 826 MW Power Plant (CCGT) at Agios Nikolaos, Greece.
With a 9HA.02 gas turbine, a steam turbine, and a 109FB turbo generator, the Agios Nikolaos power plant is one of the biggest and most efficient combined-cycle gas turbine (CCGT) power plants in Europe. In these types of power stations, several technological methods are employed to control combustion processes. Among these, the traditional usage of boilers and HRSG, which are commonly likely to damage surrounding and inner environments via harmful noise exposition. In fact, safety valves, start-up valves, blow down and flash tank have the tendency to create a very high noise level while discharging into the atmosphere.
Stopson Italiana has designed a specified soundproofing technique in order to provide a high degree of noise abatement. The equipment is silenced through the implementation of separated and well sized silencers, which tackle the source of noise directly in three different operational parts: the pressure safety valve (PSV), the start-up valve, and the atmospheric blow-down tank.
The Supply in details – technical specifications and characteristics
In details, the total supply has been designed in line with the following configuration:
- 16 vent silencers were designed for PSV, with flow rates ranging from 30 t/h to 300 t/h, temperatures up to 584°C and noise target of 115 dB(A) @ 1 m.
- 4 vent silencers designed for start-up valve with flow rates ranging from 6 to 260 t/h, temperatures up to 504°C and noise target of 100 dB(A) @ 1 m.
- 1 vent silencer applied to the atmospheric blow-down tank, performing flow rate 39 t/h, temp. up to 105 °C, 80 dB(A) @ 1m.
