Not long ago, China's Premier Wen Jiabao in Sweden at the Stockholm +40 sustainable development of the Partners.Forum in a speech that, we never at the expense of the ecological environment and people's health in exchange for economic growth. This is a Chinese environmental issues once again clear.
Rapid economic growth, resource conservation, environmental protection was established as the basic national policy of sustainable development strategy as a national strategy. Similarly, in the production of rapid growth, the pace of China's iron and steel industry energy saving are constantly moving. "Eleventh Five-Year" period, the steel industry accumulated phase out backward production capacity to 120 million tons, steel production capacity of 72 million tons per ton of steel energy consumption, emissions of sulfur dioxide and smoke dust emissions and consumption of water dropped significantly, iron and steel industry energy saving row and achieved remarkable results.
In 2011, China identified the target per unit of GDP energy consumption fell 3.5%, actually declined by only 2.01%; the total national nitrogen oxide emissions rise, not fall. With the availability of resources and environmental capacity constraints become more severe in this case, the energy saving work of the steel industry is also facing a more severe situation.
On the one hand, China's steel industry, the level of energy saving compared with the advanced international level there are still large gaps. 2011, iron and steel enterprises of China's key statistics tons of steel sulfur dioxide emissions of 1.53 kg per tonne of steel smoke dust emissions to 1.1 kg; the 2010 level of South Korea's Posco were tons of steel sulfur dioxide emissions of 0.7 kg per tonne of steel smoke dust emissions 0.13 kg. In addition, the proportion of China's steel industry tons of steel in energy costs to be higher than 10 percent of the world's major iron and steel enterprises.
On the other hand, many enterprises the enthusiasm of the energy saving declined. Iron and steel enterprises facing severe production and operation situation, and some energy-saving emission reduction targets, such as the comprehensive energy consumption of per ton of steel and the decline in fresh water consumption space is relatively limited, to further energy conservation work, their input will exist between and effect a large gap. In addition, some companies there are heavy energy-saving, the phenomenon of light emission reduction, mainly due to energy conservation can bring lower costs of energy procurement, enterprise relative power than the foot, reducing emissions is difficult to directly bring the cost of improvement and increased profits, the enterprise The input power is relatively small.
Promoting energy conservation is not only China's construction of a resource-saving and environment-friendly society, is the subjective needs of survival and development of the iron and steel enterprises. Under the current critical situation, we need the most important factor in the government and enterprises with greater determination and energy conservation as a matter of corporate life and death for assessment, governments and enterprises also need greater capital investment and implementation of efforts to promote energy abatement work is carried out.
We shall see, the steel industry to further promote energy conservation, there is still much as space.
In the process, to rely on the introduction of absorption and independent innovation to achieve new breakthroughs in energy saving technology. At present, the energy saving effect is more obvious in the forward-looking technology, such as the FINEX such as fluidized bed gas ironmaking technology, full oxygen blast furnace ironmaking technology in industrial production is still exist on the original fuel economy is not good and many other issues, these depend on the integration of industry R & D platform, greater efforts to carry out basic and cutting-edge energy saving technology. In addition, in the original blast furnace - BOF process, how to rely on the composite action of various energy saving technology and equipment to reduce consumption, but also the main direction of research and development of energy saving technology. As China's Shougang Jingtang Caofeidian steel construction based on "a new generation of recyclable steel process technology and production technology breakthrough research results is expected to accelerate the emergence of.
Secondly, the equipment, to increase the intensity out of the low production capacity and the promotion of energy saving equipment. At present, the production of small and medium-sized steel enterprises in China accounted for about industry-wide production of about 20% of the energy, and there was an expanding trend. Large gap between this part of the production capacity of energy consumption and emission levels and key enterprises, but the supervision and regulation of the difficulty of this part of the enterprise is relatively difficult, causing obstruction to the further deepening of the energy saving work. This requires the relevant government departments to increase environmental protection legislation, verification and supervision, strict implementation of the standards for admittance into industries, accelerate the elimination of low capacity, the formation of the the market Daobi mechanism in energy saving, urging the steel industry as a whole to enhance the level of energy saving to form a more fair competitive market environment.
Thirdly, management should step up efforts to rely on the system to optimize energy saving, promote business energy center building. At present, the iron and steel enterprises through the process innovation to achieve a major breakthrough in further energy saving depends on the technology, it is difficult to play an immediate effect. More realistic approach to optimize the management of enterprise energy system. At present, many enterprises to implement energy-saving technological transformation mostly to a single device or process-based, systematic poor; at the same time, the lower part of the iron and steel enterprises energy level of equipment, energy systems, monitoring, control system low level of automation.
These enterprises should strengthen their understanding of the unique advantages of the Energy Management Centre, in accordance with the concept of flat and focus on consistent, data acquisition, processing and analysis, control and scheduling, balance forecasting and energy management, functional integration, the integration of enterprise energy control .
