ABB, a power and automation technology group, and Holcim Switzerland have agreed to install ABB¡¯s newly developed heat recovery and electrical power production system at their cement plant in Untervaz, Switzerland.
ABB¡¯s production system is based on the Organic Rankine Cycle (ORC) technology that helps turn exhaust gas heat into clean electricity, meaning no fossil energy is required to run the plant, according to ABB. Through the system, waste air or stack gases with temperatures starting from only 150¢ªC can be used to generate power from 500 kW up to double-digit megawatts, ABB said.
The contract comprises engineering, project planning, delivery, installation and commissioning of the complete turnkey package consisting of all power plant components such as turbine, generator and heat exchangers. The system is expected to be in operation at the end of 2011.
