Abstract
PURPOSE: To effectively recover and utilize the sensible heat of sintered ore by introducing a circulating cooling medium raised in temp. by cooling the ore into a heat exchanger to heat blast furnace exhaust gas and using the heated gas for a top pressure turbine, a hot stove and a boiler.
CONSTITUTION: Sintered ore of 300W500°C supplied from a sintering apparatus is dropped onto moving bed 11 of the cooling apparatus and cooled with a cooling medium (cooling air) blown up from lower nozzles 13a, 13'a. The medium raised in temp. by cooling the ore is gathered with air gathering covers 13b, 13'b. At this time, the medium is circulated through the passage of nozzles 13a→cover 13b→fan F2→nozzles 13'a→cover 13'b→heat exchanger H→fan F1→nozzles 13a. Blast furnace gas of about 50°C freed of dust with dust removing apparatus 3 is heated to 100W350°C with exchanger H, and after driving top pressure turbine 4 with the heated gas to produce electric power with power generator 9, the gas is fed to hot stove 5 or boiler 6 to effectively recover the waste heat.
