In recent years, my country's iron and steel enterprises have made great achievements in energy conservation, emission reduction and green development, but the total resource and energy consumption and emissions are still high. This year, my country will carry out special supervision on the compliance of energy consumption quotas and the implementation of tiered electricity prices for 185 iron and steel enterprises. Promoting technological energy conservation is one of the important paths to develop industrial energy conservation.

Recently, the Ministry of Industry and Information Technology issued the "Letter on the Assignment of the 2018 National Major Industrial Special Energy Conservation Supervision Task". The letter shows that in 2018, the total number of national major industrial special energy conservation supervision tasks was 5,330, of which 185 iron and steel enterprises were subject to special supervision on the compliance of energy consumption limits and the implementation of tiered electricity prices.

As a "two high" industry, the progress of energy conservation and emission reduction in the iron and steel industry has attracted considerable attention. Li Xinchuang, President of the Metallurgical Industry Planning and Research Institute and Chairman of the Metallurgical Special Committee of the China Energy Conservation Association, introduced that in recent years, my country's iron and steel enterprises have made great achievements in energy conservation, emission reduction and green development. The level of energy management has been gradually improved, and the level of secondary energy recovery and utilization has been continuously improved. With the rapid popularization of high-temperature and ultra-high pressure units and ultra-high temperature and ultra-high pressure units, the level of self-generation of enterprises has increased year by year. In 2017, the self-power generation rate of my country's steel industry was close to 50%, and the total annual power generation was about 190 billion kWh.

But at the same time, the resource and energy consumption and total emissions of my country's iron and steel enterprises are still at a high level, the problem of insufficient and unbalanced green development levels among enterprises is still very prominent, and the industry is still faced with huge pressures on environmental protection and emission reduction.

In the past two years, my country's steel industry has achieved remarkable results in reducing overcapacity, and corporate benefits have improved significantly. "The more favorable the situation of the enterprise is, the more it is necessary to be vigilant in times of safety, consider the long-term, and pay full attention to the energy conservation, environmental protection and green development of the enterprise." Li Xinchuang reminded enterprises that in terms of secondary energy recovery and utilization, the field of self-power generation in the steel industry In the past ten years, extensive growth, uneconomical operation of self-owned generator sets, and high energy consumption have prevailed.

Promoting technological energy conservation is one of the important paths to develop industrial energy conservation. In order to promote the application of advanced energy-saving experience and excellent energy-saving technology in metallurgical enterprises, the "Steam Turbine Cold-End Optimization and Energy-saving Innovation Special Technology Field Promotion Conference" sponsored by the Metallurgical Industry Planning and Research Institute and the Metallurgical Industry Energy-saving Professional Committee of China Energy Conservation Association was recently held in Hebei Province. Handan City held.

According to reports, in 2017, HBIS Handan Iron and Steel Co., Ltd. implemented the "Steam Turbine Cold End Optimization Energy-saving Technology" (referred to as CES energy-saving technology), Handan Iron and Steel Group's 1# 60 MW generator set increased the power generation power by more than 7% on average, generating 16 million more electricity every year. kWh, creating economic benefits of 8 million yuan, saving 5,100 tons of standard coal, and reducing carbon dioxide emissions by 13,300 tons. Jia Guangru, deputy general manager of Hegang Group Handan Iron and Steel Company, said that in the next step, Handan Iron and Steel will continue to be committed to environmental protection improvement and innovative development, reduce energy consumption, improve efficiency, and continuously improve the overall competitiveness of the enterprise.

It is understood that compared with modern large-scale steam turbine units, there is a big gap in the design, technology and automation of steam turbines in service in the high-capacity industry, which are manifested in higher heat consumption, extensive operation control, and poor operation economy. The demand for optimization and energy-saving technological transformation of steam turbine body is very prominent.

CES energy-saving technology can reduce the heat consumption of the steam turbine and the power consumption rate of the cold end system equipment, realize the intelligent operation control of the steam turbine cold end system, improve the power generation efficiency, improve the overall operation level of the iron and steel enterprise's own power plant, and bring significant economic benefits to the enterprise. benefits and energy saving and emission reduction benefits. Shenzhen Shineng Ketai Energy Technology Co., Ltd. has deeply researched CES energy-saving technology, and has owned a number of invention and utility model patents.

Experts said that the current total annual electricity consumption of the steel industry is about 400 billion kWh. If the CES energy-saving technology can be fully applied in the steel industry, if the average power generation power is increased by 5%, the annual power generation can be increased by about 8 billion kWh, creating economic benefits. The benefit is about 4 billion yuan.
