Planning and execution of a noise protection measure for a geothermal power plant
The geothermal power plant consists of the following components:
- 12 air-cooled condensers, each 160,000 m³/h
- OCR turbine units
- Cogeneration unit
- Technical center
- Preheater and evaporator unit
In order to comply with the requirements according to TA-Lärm dated August 26, 1998, an all-round noise protection housing with two air-inlet- silencer on the front, was planned and implemented.
The scope of services included the creation of the statics for the wall construction, the formwork and reinforcement plans for the foundations, the complete construction of the LSW, as well as manufacture, delivery and assembly of the steel structure, wall elements, silencers and access gates.
The measure was successfully completed in March 2021.
Noise reduction concept for exhaust device Niederauer Mühle:
Due to the exposed situation of the paper factory, nearby to the small city Kreuzau, high acoustic requirement of minus 40dB noise power level had to be fulfilled. The exhaust blowers all together share in the same chimney and on the top the acoustic properties should meet the requirements of “TA Lärm”.
After eight weeks work and erecting of:
- 12 pipe silencers
- 700 sqm capsule surface
- 11 doors R’w 52dB
- Several sound absorbing silencers
- Shock absorbers for the blowers
Contrast Akustik Ltd. fulfills all successfully.
