Industrial Noise Control

Ergil’s significant contribution to sustainable development in alternative energy sector: geothermal silencers!

This case study gives ideas about the significance of geothermal energy in terms of sustainable development and the functions of ERGIL’s innovative products mainly silencers and weir boxes to be effective solution for community concern in a geothermal power plant. It is possible to explain some parts of this context by exemplifying process of designing, fabricating and delivering of 13 silencers & weir boxes to Zorlu Energy Group’s Kizildere III - Geothermal Power Generation project which is a very important development for alternative energy sector in Turkey and international arena in terms of being a vital project to meet approximately 800,000 dwellings’ electricity needs by increasing production capacity to 165 MW/.

Estimated Emission Levels by Pollutant and Energy Source of Power Plants

How effectively does geothermal help in improving air quality and decreasing greenhouse gas emissions?

At geothermal power plants, billows seen rising from cooling towers are composed of water vapor or steam, not burned fuel or smoke emissions, and are caused by the evaporative cooling system. A binary or flash/binary geothermal plant produces nearly zero air emissions; air emission levels at dry steam plants are considered to be slightly higher because even without human intervention, geothermal systems already contain naturally-occurring dissolved gases. The exact relationship between human-caused and naturally occurring geothermal emissions at geothermal power plant sites is difficult to characterize and varies based on the site’s unique resource chemistry, the resource temperature, type of power plant, and a number of other factors. In summary, though, geothermal technology is considered environmentally benign and any emissions are negligible when compared with using technologies that involve combustion of fossil fuels.

Zorlu Energy Group Addressed High Noise Levels At Its K?z?ldere Iii Geothermal Plant

How do geothermal developers control noise levels?

During drilling, temporary noise shields can be constructed around portions of drilling rigs. Geothermal developers use standard construction equipment noise controls and mufflers, shield impact tools, and exhaust muffling equipment. Once the plant is built, noise from normal operation of power plants comes from cooling tower fans and is very low. Turbine-generator buildings, designed to accommodate cold temperatures, are typically well-insulated acoustically and thermally and are equipped with noise absorptive interior walls.

When noise issues arise, they can be dealt with effectively in ways that do not impact plant performance Zorlu Energy Group addressed high noise levels at its K?z?ldere III geothermal plant: “In response to unexpected high noise levels experienced during the start-up of ERGIL team worked diligently to design Silencers and Weir Boxes. The purpose of the Silencer is to significantly reduce the sound levels caused by the acoustical energy flowing in the discharge piping of the turbine, without affecting turbine performance and plant output. The purpose of the Weir Box is when Tanks are filled with geothermal water and the silencer quietens the process as the steam and steam fluids which come out of the double sludge system are removed and the geothermal water is then transferred to the liquid weir boxes, where level and flow measurements are carried out. ‘’The final product not only addressed a technical issue but also helped the Zorlu Energy Group effectively respond to community concern about noise levels from the plant.
