Italy: Exergy has signed a contract with Cementi Rossi for a 3.5MW organic rankine cycle (ORC) waste heat recovery (WHR) system to be installed at the Pederobba plant near Treviso. The scope of the contract includes engineering, design, site erection, commissioning and start up of the power plant and a long term after sales service.

Exergy designed a customized and compact ORC solution to convert approximately 16MWt available from exhaust heat in the clinker cooler into 3.5MW of electricity utilising an air cooled condensing system, a radial outflow turbine as expander and choosing a non-flammable fluid to grant maximum safety during plant operation. The electricity produced by the ORC module will feed approximately the 30% of the energy demand of the cement plant.

“Our ORC WHR systems, leveraging on the higher efficiency of the radial outflow turbine, can help to boost at maximum level the performance of cement plants. For Cementi Rossi in particular we worked to supply a tailor made solution, choosing a non-flammable fluid in the cycle and a very compact plant design with a high level of prefabricated components to reduce costs and time for erection,” said Claudio Spadacini, the chief executive officer (CEO) of Exergy.
