Objective
STEEL PRODUCED IN BLAST FURNACES IS DELIVERED IN SLABS WHICH ARE COOLED AND SENT TO STEEL MILLS FOR FURTHER MANUFACTURING (STRIPS, PLATES, ETC.). BEFORE ENTERING IN THE STEEL MILLS, THE STEEL HAS TO BE REHEATED IN FURNACES TO HIGH TEMPERATURES (1200 DEGREES C). THESE REHEATING FURNACES ARE MAJOR FUEL CONSUMERS: A FURNACE OF THIS TYPE HAS A YEARLY CONSUMPTION OF 40,000 TO 50,000 TOE. (3 OR 4 SUCH FURNACES ARE REQUIRED FOR THE PRODUCTION OF 4 MILLION TONS OF STEEL PER YEAR).
THE AIM OF THIS STUDY IS TO DECREASE THIS CONSUMPTION BY IMPROVING THE EFFICIENCY OF THE HEAT EXCHANGERS WHICH PREHEAT COMBUSTION AIR USING THE EXHAUST GASES OF THE FURNACE (AT 1000 DEGREES C). THEY CURRENTLY HAVE AN EFFICIENCY OF 25 % AND THEIR REPLACEMENT BY NEW AND MORE ADVANCED HEAT EXCHANGERS WITH AN EFFICIENCY OF 50 % COULD LEAD TO IMPORTANT ENERGY SAVINGS (4,000 TOE PER FURNACE PER YEAR). THE PAY BACK TIME OF THESE INVESTMENTS IS HOWEVER TOO LONG (AROUND 5 YEARS). THE AIM OF THE PRESENT WORK IS THEREFORE TO EXAMINE WAYS IN WHICH THE EXISTING HEAT EXCHANGERS CAN BE IMPROVED BY SIMPLE MODIFICATIONS WHICH HAVE A SHORT PAY BACK TIME.
THE WORK CARRIED OUT CONSISTED OF SIMULATING THE HEAT EXCHANGER WITH A COMPUTER MODEL. THIS WAS BASED ON EXPERIMENTS CARRIED OUT ON A 1/5 SCALE MODEL AND ON MEASUREMENTS CARRIED OUT IN AN INDUSTRIAL PLANT.

Funding Scheme
Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.
