Exergy signs WHR contract with Cementi Rossi
27 July 2018

Cementi Rossi SpA awarded Exergy the contract for a 3.5MW ORC waste heat recovery (WHR) system to be installed near the cement producer's plant in Pederobba, near Treviso, Italy.

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 customised and compact ORC solution to convert approximately 16MWh available from exhaust heat in the clinker cooler into 3.5MW of electricity using an air-cooled condensing system, the highly-efficient Radial Outflow Turbine as expander and choosing a non-flammable fluid to ensure maximum safety during plant operation.

The electricity produced by the ORC module will feed around 30 per cent of the plant's energy demand and is expected to improve the cement works' overall efficiency and profitability while reducing also the environmental impact. Once operational, the new ORC unit will enable the Pederobba facility to reduce its fossil fuel use by 5400tpa (oil equivalent) and 17,000tpa of CO2 emissions.

Claudio Spadacini, Exergy’s founder and CEO, comments: “Waste heat recovery technology is a very profitable and proven solution for cement manufacturing process. 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. We are happy to have partnered with Cementi Rossi for this project and hope to develop others with them. Cement is one of the key application to develop for our WHR market in the future.”
