Gea installs two waste heat recovery plants in India and Italy

A Gea Emission Control technology solution enables electricity and compressed air to be generated from otherwise unused waste heat from flat glass production lines. Two plants for waste heat recovery in flat glass production lines of the Saint-Gobain Group at locations in India (Sriperumbudur) and Italy (Pisa) have now been commissioned. In Sriperumbudur, the plant is producing electricity, while in Pisa the production of compressed air and thermal energy for ambient heating are also important factors for the plant. However, both locations have one thing in common: Saint-Gobain can significantly improve energy efficiency in production and save resources with this Gea solution. This is also shown by the characteristic data obtained to date. Waste heat recovery unit at Sriperumbudur (India) plant. Photo – GEA In both plants, the waste heat is extracted from the flue gas in a heat exchanger and transported to an ORC (Organic Rankine Cycle) via a thermal oil circuit at high temperatures around 300°C and with high flexibility. From this, in turn, electrical power is produced. In addition, a compressor is…
