Energy Recovery Plants
The metal industry energy consumption is one of the most debated environmental concern at nowadays. Resources efficiency becomes the remarked keyword. The dimension of call for energy efficiency stretched out from the understanding real energy requirement of machineries to the size and configuration of auxiliary systems. Energy efficiency means as well automatization of start-stop based on real effective necessary of the running. Optimization and deep understanding are provided by the automatic management software based on the database of information collected over the plant by implementing an efficient management of the plant activities drive to save significant (7-10%) energy losses.
Major energy saving of 15-20% can be achieved by implementing a proper assessment and optimization of management software system, based on elaboration historical database.
Recovery of the heat (CHR™) from the EAF primary fume (or from the Reheating furnace) is one of the standard and most efficient way to recover the exhausted energy. The feasible target is to recover those 30% of otherwise lost inlet energy and produce electricity for the plant use with an efficiency of 17%, recovery 25 kWh/ton, by applying flexible, adaptable and compact layout, with 3-4 years of return of investment.
The innovation prospective of next future is driving Danieli to development of technologies for the low temperature heat recovery able to generate energy directly using thermoelectric synthetic materials which are more reliable and environmental friendly. The TEG (thermoelectric generator) systems combined with the ORC will improve significantly the environmental footprint of the manufacture providing to the final use a certificated green product.
Alternative energy recovery way has been implemented also through the absorber chiller technology to produce chilled water for cooling process and HVAC system.
