Traduction de «Polvere di carbone » (Italien → Anglais) :

Emissions from combustion, including flue gas scrubbing, and from process materials including coke, graphite and coal dust shall be monitored in accordance with section 1 of this Annex.

The operator shall include at least the following potential sources of CO2 emissions: decomposition of alkali- and alkali earth carbonates as the result of melting the raw material, conventional fossil fuels, alternative fossil-based fuels and raw materials, biomass fuels (biomass wastes), other fuels, carbon containing additives including coke, coal dust and graphite, post-combustion of flue gases 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

carbon containing additives including coke and coal dust,

1 part by weight of vegetal carbon dust (beechwood) with a particle size of 0-100 μm,

(24) Dust from steel shops is normally treated through two different processes: the so-called Waelz process, which involves burning the dust mixed with coke and sand at high temperatures and whose main disadvantage is the production of very low value slag and the emission of high quantities of combustion gases; and the chemical stabilisation/solidification process, which, by mixing the dusts with other elements, allows the resulting waste to be dumped in controlled sites since it can be classed as non-toxic and non-dangerous.
