Energy-Saving & Discharge-Reduction Appeared Good Trend in Changjiang Deltası Bölgesi Çimento Endüstrisi

    Bu yılın Kasım ayına kadar 56 şaftlı fırın silindir fabrikası işletmesi kapatıldı. Zhejiang Belediyesi İl ve 68 işletme Jiangsu Belediyesi il. Bu iki ilde bu yıl 24 milyon ton şaft fırını ve diğer silindir üretimi olacağı tahmin ediliyor. Ocak-Kasım ayları arasında Jiangsu Belediyesi ve Zhejiang Belediyesi eyaletlerinde çimento silindiri üretim hacmi %12 ve %10 azalırken, bu iki ilin çimento silindiri üretim hacminin bu yıl 15 milyon ton azalacağı tahmin ediliyor. 
    Changjiang delta bölgesi Çin’s largest cement production ve consumption base. 10 2006, the cement cylinder production volume in Şanghay, Jiangsu Belediyesi, Zhejiang Belediyesi ve Wuhu, Tongling, An’qing, Xuancheng, Chizhou etc cities in the south of Hunan province, amounts to 184 million tons, 21% of national total volume, cement production volume is 240 million tons, 19.4% of national total volume; total energy consumption in cement production is 24.5 million tons of stveard coal, 18.7% of national cement manufacture; total coal consumption in cement production is 30.24 million tons, 18.5% of national cement manufacture; wasted air discharge total volume 697.2 billion stveard m3 , 17.1% of national cement manufacture wasted air discharge volume; 0.112 million tons of SO2, 10.8% of national volume, 0.62 million tons of discharged power ve smoke, 10.9% of national volume. 
    2007 yılında, silindir üretim hacmi Jiangsu Belediyesi ve Zhejiang Belediyesi has declined; however, their cement production volume was increased by 6.1% ve 4.7% respectively. The cement cylinder in Şanghay, Jiangsu Belediyesi ve Zhejiang Belediyesi are mostly provided by cement enterprises in An’hui, Jiangxi Belediyesi, ve Hubei Belediyesi, these Changjiang River Bank cities. The cylinder production in An’hui province has increased by 10 million tons this year. Wuhu, Tongling, An’qing, Xuancheng, Chizhou etc cities in the south of Hunan province by using the advantages of recourse ve convenient Changjiang golden transportation, the cylinder production in 2006 was 47.21 million tons, 35 million tons of with were sent out of delta ve Çin. Till November of 2007, the cylinder production volume in south of Huibei kept increasing, up to 48.23 tons, increase by 20%, ve 37 million tons of which are sent out delta ve Çin. It can be said that the promoted production in An’hui ve south of Hubei Belediyesi replaced that of Jiangsu Belediyesi ve Zhejiang Belediyesi provinces. 
    The cylinder production location changing in Changjiang Delta has its resource reason ve economy reason. Since 2004, the cement enterprise in Şanghay, Jiangsu Belediyesi ve Zhejiang Belediyesi have bought the coal at very high prices, ve Zhejiang Belediyesi bought the coal at the highest price in the country, at price of 570 Yuan above per ton. Jiangsu Belediyesi işletmeler 2004 yılından bu yana ton başına 500 Yuan civarında fiyatlarla çimento satın aldı; İşletmeler Jiangsu Belediyesi ve Zhejiang Belediyesi have bought coal at prices 80~130 Yuan higher than that of surrounding places. As the high economic development, the people’s salary in Jiangsu Belediyesi ve Zhejiang Belediyesi çevredeki yerlerden çok daha yüksekti. 2006 yılında, maaş Şanghay was about 29000 Yuan per year, ve the Jiangsu Belediyesi ve Zhejiang Belediyesi have also arrived 21000 ve 16000 RMB respectively. Through comprehensive calculation, the cost of cement production in Zhejiang Belediyesi ve Jiangsu Belediyesi çevredeki yerlerden ton başına 20 ~ 25 Yuan daha yüksek olacak. Son zamanlarda, Zhejiang Belediyesi cement companies’ capital was invested in Anhui Dili, Jiangxi Belediyesi, Şangay Belediyesi, Çin Mutfağı, Liaoning, Heinongjiang vb. Nanfeng, Shangfeng, Sanshi vb büyük ölçekli çimento şirketleri Zhejiang Belediyesi has established cement cylinder ve cement providing base in Jiangxi Belediyesi Jiujiang, Anhui Dili Tongling ve Xuchen. The cement industry in Şanghay has been declined continuously, only several large-sized cement enterprises ve cement grinding station left. After the fast development since 2004, the cement industry in Zhejiang Belediyesi ve Jiangsu Belediyesi uzun süredir duruyor.
    Cement cylinder production location exchanging is the result of cement production specialization ve socialization, the result of the activities of large-size cement companies. In the cylinder production in Hubei Belediyesi district companies, the new type dry process takes 96.57 percentage; Sanshi, Shangfeng, Tongxing ve Hailuo etc, 4 large-size cement enterprises in Zhejiang Belediyesi ve An’hui controlled 90% of the cylinder production in this district. The stveard coal consumption of the cement enterprises in south of Hubei Belediyesi şundan düşüktü: 110 kg/ton, much lower than national stveard, ve the discharging of SO2 was 0,42 kg/ton, firstly get the requirement of Air Polluting Discharging Stvear of Cement Industry before 2010. Only if they implement the policy ve environment protection stveard, it is possible to make air pollution in the south of Hubei Belediyesi keep present level. The cement industry in Jiangsu Belediyesi ve Zhejiang Belediyesi must follow the trend of development, keep on take away backward productivity, forbid to establish plants in the place without limestone, make ve implement the local stveard with will be stricter than Air Polluting Discharging Stveard of Cement Industry. Chiangjiang River Delta, the largest cement production ve consumption base, can be able to reduce the polluted air discharging. The cement industry in Zhujiang River Delta ve Bo Sea surrounding districts have also appeared such phenomena. If the local governmental supervising department follows the economy circulating regulation, strictly implement environment protecting stveard, the reduction of main polluting air discharging in the cement industry can be realized.
