In the Solignano Ceramiche Piemme plants SACMI technology has been chosen to create a large cogeneration system which, by producing electricity through a jet turbine powered by methane, will save 6.7 million cubic metres of gas and 13.2 tonnes of CO2 every year.
This is a sustainable choice that uses the latest-generation software and reduces consumption through a cutting-edge system for the recovery of heat contained in the turbine’s exhaust fumes.
“We are very pleased with this investment, which allows us to further improve our productivity," explains Sergio Bondavalli, CEO of Ceramiche Piemme. "At this difficult time for our sector and for the economy in general, it is crucial that we lead the way in terms of sustainability so that we can look to the future with confidence; this measure will allow us to dramatically reduce CO2 emissions into the atmosphere and to supply the daily needs of our plants."
The installed system is designed to handle 53,000 normal cubic metres per hour of exhaust fumes at 500 degrees. Channelled by the turbine into a large, almost 140 metre-long duct (1.7 metres in diameter), the fumes are directed to the two SACMI atomisers, ATM 036 and ATM 065, reducing the factory’s methane requirements by 6.7 million cubic metres of gas per year (equal to 13.2 tonnes less CO2 released into the atmosphere).
"The special feature of this system is the fluid dynamics used to design the entire duct in which the fumes are channelled from the jet turbine to the atomisers, despite its length." explains Stefano Orlandi, SACMI Forni Product Manager Energy Management. "This is combined with special insulation that significantly reduces the dispersion of heat, which is entirely channelled into the atomisers, and allows Ceramiche Piemme to supply almost all of the factory's requirements.".
Ceramiche Piemme and SACMI are also working to implement a management system that in the future will be able to predict the energy requirements of each machine in advance, further reducing consumption and consequently emissions.
