East pot collaborative decontamination advantage highlights

As the most important power production method in China, coal-fired power generation has also become the main source of atmospheric pollution and has become the focus of environmental governance. Therefore, promoting the "ultra-net emissions" of coal-fired units is the top priority for the sustainable development of the coal-fired power industry. In this key link, Dongfang Electric Group Dongfang Boiler Co., Ltd. has taken the lead, and its "ultra-clean discharge" technology and equipment have won the favor of the market. On September 24, Dongfang Boiler held the “ultra-net emission” technology exchange meeting for coal-fired power plants, and its package of collaborative solutions for all types of pollutants has aroused widespread concern among users.

"Ultra-clean emissions" is by no means a word game. What the user wants is the actual operation effect. On July 18th, the first 300,000 kilowatts of coal-fired units with the Dongfang Boiler's "low-nitrogen-burn + SCR flue gas denitrification" technology were formally put into operation at Guangzhou Hengyun Power Plant. After on-site measurement, the emission values ​​of dust, sulfur dioxide and nitrogen oxides of Unit 9 were 1.7, 1, 23 mg/standard cubic meter respectively, which was lower than the national gas generator set emission standards (smoke 5, sulfur dioxide 35, nitrogen oxide 50 mg/ Standard cubic meters), to achieve the best level of environmental protection of similar domestic units.

This market reaction is the result of thick and thin hair in the Dongfang. According to Xu Peng, General Manager of Dongfang, Dongbu has always been committed to the efficient power generation and clean discharge of power station boilers. In recent years, it has also increased the research and development of “ultra-net emissions”, built various experimental platforms, and developed a Series of world-leading new technologies and new products, such as ultra-low nitrogen combustion technology, efficient denitrification technology, high efficiency wet desulfurization and semi-dry desulfurization technology, high efficiency wet electrostatic dust removal technology, low-low temperature economizer, water media smoke Gas heat exchangers and other technologies and products. These technologies have also been recognized by the market. In April 2013, the world’s largest capacity 600 MW supercritical CFB boiler was successfully put into operation at Baima Power Plant in Sichuan. This CFB furnace is independently developed by Dongfang Power Plant. The use of clean coal power generation technology, the National Development and Reform Commission expert group unanimously held that: This is a major breakthrough made by China's electricity major environmental protection technology and equipment, made a milestone.

As of September of this year, Dongfang has signed a total of 391 sets of denitrification units, with a total cumulative output value of 10 billion yuan, and the market share ranks first in the domestic industry. Dongping General Contracting Co., Ltd. CLP Henan Power Co., Ltd. Pingdingshan 2 × 1 million kilowatts unit project, won the national gold prize for quality engineering; independent research and development of large-scale power plant boiler SCR tail flue gas denitrification equipment, was listed as a national key new product plan; The 600,000 seawater desulfurization technologies developed have been exported to Turkey; 300,000 units of seawater desulfurization have won the second prize of the China Machinery Industry Science and Technology Award; 600,000 units of seawater desulfurization have won the third prize of scientific and technological progress in Sichuan Province; Dongbu seawater desulfurization technology was selected in the 2014 national Ministry of Science and Technology and Ministry of Environmental Protection, “Compilation of Advanced Technologies for Prevention and Control of Atmospheric Pollution”.

In June 2014, after careful technical selection, Dongfang Boiler introduced advanced wet electrostatic precipitator technology widely used in chemical, smelting, thermal power plants and other industries around the world from Germany's ENVIé„„ROTHERM, marking the Dongfang Boiler After introducing, researching and developing the technology of flue gas desulfurization, denitrification and denitration catalysts for thermal power plants, it has entered the field of flue gas dust removal from thermal power plants. At this point, Dongfang Boiler has formed a complete and systematic package solution for all types of pollutants. This is the technical strength that Dongbu relied on for many years of technical accumulation and will take full advantage in the fierce market competition in the future.

On September 12, the National Development and Reform Commission, the Ministry of Environmental Protection, and the National Energy Administration issued the Action Plan for the Upgrade and Reconstruction of Coal-fired Energy-Saving Emission Reductions (2014-2020), which puts forward a higher level of coal consumption and pollutant emissions for power generation. Standards and requirements. The policy forced the company to indicate the market direction. For Dongfang, it is both pressure and motivation. It is worth mentioning that Xu Peng emphasized that Dongfang Boiler is not only a provider of superior technology and products, but also a provider of quality services. This may explain the strategic positioning of collaborative solutions from another perspective.
