Steelmaking is an energy-intensive industrry, which offers various opportunities to recover energy and waste heat, increasing process efficiency and improving the environmental standards.
For this purpose, Danieli Environment has developed the CHR™ - Clean Heat Recovery system to transform EAF (Electric Arc Furnace) hot fumes into electric energy.
It is well known that EAFs lose a huge volume of thermal energy through the primary fumes. This is an interesting energy source, especially if compared with renewable energies.
Our system combines Hot Water cooling and ORC (Organic Rankine Cycle) technology to produce electric energy and recover waste heat from the EAF, with a consequent savings of fuel and reduction of green-house gas emissions.
The first CHR™ plant was installed in 2014 at cciaierie Bertoli Safau S.p.A., the Danieli Group's steelmaking company in Udine, Italy.
