170 The outdoor noise enclosure is a part of the power plant PT Energi Sengkang power plant located in Southern Sulawesi, Indonesia. The owner is Energy World Corp. Ltd. Wendt SIT GmbH & Co KG delivered two noise enclosures to cover Siemens gas turbines. The two units are designed equal. WENDT was ordered to deliver these noise enclosures with a completely new design which is expected to become an execution standard for future projects. The noise enclosures are designed for an outdoor arrangement with the purpose to replace the turbine building of the power plant. This manner leads to an enormous cost reduction and was one of the important arguments for the positive decision of the customer to this kind of execution. The shown noise enclosure has the function to reduce noise emissions caused by a gas turbine and its connected generator. The enclosure is divided into 4 different compartments, one for the gas turbine, one for the auxiliary, one for the Lube oil and one for the generator. Special operation conditions have to be considered during design period to meet the technical requirements of the project. The enclosed machinery has a big heat loss, so the noise enclosure has to be equipped with a ventilation system to fulfil maximum interior temperatures lower than 60°C. Higher temperature inside would be harmful for the electrical equipment and would also not allow access of maintenance personnel during operation. Special attention was paid to the hazardous area inside the gas turbine compartment which is possible to occur by a leakage in the turbo machinery system. The noise panels of the enclosure have the advantage to be removable without loosing any connection elements. The wall and roof elements are executed weather- and gas tight as well. Above of the generator building is a filter house. The loads resulting from this filter house are derived by its own steel structure. During the design period a lot of interfaces of components had to be considered. Several penetrations caused by the generator bus duct, turbine diffuser, ventilation ductwork and piping had to be integrated into the design of the noise enclosure. Static System: The static system of the noise enclosure in the transverse direction consists of frameworks. In longitudinal direction the building is stabilized by roof and vertical bracings. The static analysis according EC3 is calculated using a 3D-model to optimize the weight of the structural steel.
