The total energy consumption of iron and steel in our country for the first time in 30 years
2015, China's iron and steel industry, the total energy consumption in the past 30 years, the first drop." On January 18, in Beijing, Tianjin and Hebei blue (Beijing) Internet Technology Co., Ltd established the signing ceremony, late Jingdong, vice president of the China Iron and Steel Industry Association said that in the grim situation, the iron and steel enterprises to take various measures to meet the requirements of the new environmental law, but also paid a great price. However, if you do not engage in energy saving and environmental protection, there is no space for the survival and sustainable development of steel enterprises.
Late Jingdong pointed out that during the "Twelfth Five Year Plan" period, the iron and steel industry, the comprehensive energy consumption per ton steel has been reduced to a less than 580 kilograms of standard coal / ton. Because of the steel production process, technology, equipment has reached a certain level, every 1 kg of standard coal to reduce the comprehensive energy consumption of Dun Gang is very difficult. At the same time, China in 2015, crude steel production fell by 2.3%, coupled with the comprehensive energy consumption of per ton steel decreased, the industry's energy consumption total more than 30 years to the first year-on-year decline. "Energy consumption decreased the total amount not only is steel production decline caused, is mainly due to the progress of energy-saving emission reduction technology leads to the comprehensive energy consumption per ton steel decreased." Chi Jingdong stressed.
With the decline in the total energy consumption per ton of steel and the comprehensive energy consumption, emissions of various pollutants have been reduced greatly. It is understood that the "1025" planning to develop the new water consumption per ton of 4 tons, while in 2015 China's steel industry fell to 3.26 tons. "In the whole world, the advanced state of the art and steel enterprises are not generally able to achieve this level of." At present, the iron and steel enterprises in the vast majority of sintering machine are supporting the desulphurization facilities, sulfur dioxide emissions has been reduced to a 0.88 kg / ton of steel, and the goal of "Twelfth Five Year Plan" is reduced to less than 1 kg / ton of steel.
Late Jingdong also stressed that although the steel industry in terms of energy saving and environmental protection has made very big progress, but in the treatment of certain pollutants with the international advanced enterprises there is a gap, such as sintering denitrification is not technically reliable and economically viable technology.
