POSCO Gwangyang steel plant

POSCO Gwangyang steel plant is a steel plant in South Korea with a reported capacity of 22,999,000 t of steel. It produces crude steel from iron ore (blast furnace) or scrap (electric arc furnace). It is operated by POSCO Holdings Inc. By capacity it ranks #1 of 16 steel plants tracked in South Korea. It emits about 34,799,208 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 8,111,703 cars. Its CO₂ per unit of capacity is about 180% above the median steel plant.

文脈内で：この施設がどのように比較されるか

22,999,000 t of steelで、POSCO Gwangyang steel plantはSouth Koreaのsteel plantの中央値はるかに上 2,101,000 t of steelです。 容量あたりのCO₂は、steel plantの中央値上約2472%です。 サブセクター：iron-and-steel。 steel plantとして、その中核的な産業操業に対して激しいプロセス熱（通常800–1500°C）が必要です。この熱はボイラー、炉、または直接燃焼によって供給される必要があり、未断熱容器および配管からの損失は無駄な燃料を表します。モジュール式脱着可能な断熱は、これらの損失を80～96%削減でき、表面を≤45°Cに冷却でき、回収期間は通常2年未満です。 製鉄所は高炉で石炭を燃焼させるか、電気アークを使用してスクラップを溶融します。どちらの場合でも溶融金属は1,500°C以上に保つ必要があり、広範な高温配管および容器を通じて転送されます。
