Translation of "in-and-out furnace " (English → French) :

The operator shall include at least the following potential sources of CO emissions: raw materials (calcination of limestone, dolomite and carbonatic iron ores, including FeCO), conventional fuels (natural gas, coal and coke), reducing agents (including coke, coal and plastics), process gases (coke oven gas — COG, blast furnace gas — BFG and basic oxygen furnace gas — BOFG), consumption of graphite electrodes, other fuels and waste gas scrubbing.

The operator shall include at least the following potential sources of CO emissions: raw materials (calcination of limestone, dolomite and carbonatic iron ores, including FeCO), conventional fuels (including natural gas and coke/coke breeze), process gases (including coke oven gas — COG, and blast furnace gas — BFG), process residues used as input material including filtered dust from the sintering plant, the converter and the blast furnace, other fuels and flue gas scrubbing.

All processes directly or indirectly linked to the process units blast furnace, hot metal treatment units, blast furnace blowers, blast furnace hot stoves, basic oxygen furnace, secondary metallurgy units, vacuum ladles, casting units (including cutting), slag treatment unit, burden preparation, BF gas treatment unit, dedusting units, scrap pre-heating, coal drying for PCI, vessels preheating stands, casting ingots preheating stands, compressed air production, dust treatment unit (briquetting), sludge treatment unit (briquetting), steam injection in BF unit, steam generation plant, converter BOF gas cooling and miscellaneous are included

The operations are restricted to processes for the recovery of iron and iron alloys (blast furnace, shaft furnace and hearth furnace) and non-ferrous metals (Waelz rotary kiln process, bath melting processes using vertical or horizontal furnaces), provided the facilities meet as minimum requirements the emission limit values for PCDDs and PCDFs laid down in Directive 2000/76/EC of the European Parliament and of the Council of 4 December 2000 on the incineration of waste (1), whether or not the processes are subject to that Directive, and without prejudice to the other provisions of Directive 2000/76/EC where it applies and to the provisi ...[+++]ons of Directive 96/61/EC.

3.11. blast furnaces including the furnace cooling system, hot-blast recuperators, dust extractors and blast-furnace exhaust-gas scrubbers and direct reducing cupolas, including the furnace cooling, gas converters and pans for melting, re-melting, de-gassing and casting of steel and non-ferrous metals;

The parties have given examples of the dual use of furnaces in the cement industry; main fuels such as coal are burnt in a primary furnace, meeting some 70 % of energy requirements, and cheaper fuels or waste materials are burnt in a secondary furnace to meet the remaining third of requirements.
