DANIELI ENVIRONMENT
Client name:
DANIELI ENVIRONMENT
Plant Location:
POZZUOLI DEL FRIULI (UD), ITALY
Date of implementation:
2014
Plant size:
MAX 1.2 MWE
Application:
HEAT RECOVERY (STEEL MILL)
Model Used:
EPSD 110
Water or cooling agent:
COOLING WATER FROM COOLING TOWER
Generator voltage:
LV
Installation:
OUTDOOR
EXERGY‘s solution was the installation of the ORC system for waste heat recovery with EXERGY‘s Radial Outflow Turbine. The ORC technology is applied to the electric arc furnace (EAF) and, by exploiting the hot waste gas generated by the steel mill, it produces 1 MWe. The heat from the waste gas is extracted using an intermediate fluid which then vaporizes the organic fluid in the ORC abstorbing the energy, before passing the turbine. Here it expands, causing the turbine to spin and creates electricity at the generator. By installing EXERGY’s EPSd Radial Outflow Turbine, the client was able to recover the maximum amount of energy, thus increasing the electrical efficiency of the installation.
The ABS plant now produces electricity with zero extra emission saving 2.900 tons of CO2 and 1.499 tons of oil equivalent per year.
