Production of Steam / Hot Water
Tenova's Energy Recovery Systems for EAF / BOF are the perfect solution for Steam and Hot Water Production. 25-30% of the energy input in industrial furnaces is lost in waste gas and cooling water. The Tenova i Recovery® technology can recover up to 70% of the energy that would be lost.
The iRecovery is part of the iSteel technology portfolio.
Energy efficiency is a topic that gets more and more importance to all potential customers in the steel and non-ferrous metal industry. 25-30% of the energy input in industrial furnaces is lost in waste gas and cooling water. The Tenova i Recovery® technology can recover up to 70% of the energy that would be lost.
i Recovery® technology is a heat recovery cooling system for different industrial furnaces, among others the electric arc furnaces (EAF), submerged arc furnaces (SAF), basic oxygen furnaces (BOF), walking beam furnaces and pusher type furnaces.
The difference between i Recovery® technology and conventional cooling systems is that energy losses in the waste gas are now recovered as steam.
The combination of heat recovery system with sophisticated control technology and a wide range of tools for steam buffering, applied to electric arc furnaces and submerged arc furnaces is the innovation that Tenova is bringing into the market.
The energy recovered can be flexibly used for process steam, heating purposes and power generation. Moreover, Tenova heat recovery technology brings advantages during the operation phase which avoid, among others, problems with corrosion or temperature peaks.

Customer Project name Energy Recovery System ORI Martin Brescia, Italy 2015
In year 1998 the Consteel steel plant was installed in Brescia Italy. After 16 years it was upgraded with a heat recovery system. The recovery system was installed to recover the remaining thermal energy in the off-gas for the production of steam. The iRecovery system will deliver thermal and electrical energy to the city of Brescia.
An ECS heat recovery system, iRecovery , was installed by the end of 2015 at the ORI Martin steel plant of Brescia in Italy. This system, installed downstream of the EAF Consteel furnace, will have the task to recover part of the energy contained in the fumes generated during the scrap melting and superheating process in the electrical furnace.
The energy extracted from the fumes will convert the recirculation water of the cooling curcuit into steam. This phenomenon is made possible thanks to the use of cooling water at boiling conditions that, circulating and absorbing energy, will be subject to partial phase change generating steam. During winter time the steam produced will be sent to a heat exchange unit dedicated to district heating for the town of Brescia managed by A2A company.
During summer time the steam produced will be used to feed an ORC (Organic Rankine Cycle) turbogenerator for the production of electricity for internal use. It is essential to consider that the new heat recovery system will have no influence on the steel production process of Ori Martin.
