Every winter, with the sudden drop in temperature in most parts of the north, people's attention to heating is accelerating. At the same time, accompanied by heating, burning coal cause fog and haze, and "coal to electricity," "coal to gas," the high cost required, but also to balance environmental protection and economic efficiency of difficult trade-offs.
However, you know, China Enfi has solved the waste heat utilization with its core expertise in waste heat boiler technology. Whether it is environmentally friendly or economical, it is called waste energy recovery.
The waste heat boiler is the core non-standard equipment with independent intellectual property rights of China Enfei. It can fully recover the waste heat from high-temperature exhaust gas, waste residue or waste liquid in various industrial processes, and is an indispensable equipment for realizing industrial energy-saving and emission reduction.
The waste heat boiler can fully cool the “three wastesâ€, use the waste heat while laying a good foundation for safe discharge, turn the water into high-temperature and high-pressure steam, and steam drives the steam turbine to generate electricity or heat, so as to meet the needs of production and living users.
Through the waste heat recovered by China Enfei Waste Heat Boiler, there is no need to consume any fuel, and power generation, heating, and domestic hot water supply are all indispensable!
Daye nonferrous metal China Ltd. Enfield total package waste heat boiler for example, the amount of steam 110 t / h waste heat boiler (steam pressure 4.6 MPa, steam temperature 260 degrees Celsius) for all the heat generated by such heating, It can guarantee the warmth of the heating season of 150,000 households (90 square meters of residence). In other words, there is such a waste heat boiler that can solve the heating problem of a small town with a population of about 450,000!
Since the 1950s, Enfei of China has started research and development of waste heat boilers and related technologies that are compatible with nonferrous metallurgical furnaces. After years of hard work, China Enfei has completely broken the foreign technology blockade and market monopoly by virtue of the waste heat boiler expertise with independent intellectual property rights, and the technical equipment level ranks among the international first, in terms of furnace suitability, process load fluctuation adaptability, and operation. The rate has great technical advantages, and the cost can be reduced by 50% compared with other waste heat boilers of the same size.
At present, China Enfei Waste Heat Boiler and related technologies have obtained 21 national authorized patents, including 15 invention patents, one national patent gold award, the first provincial and ministerial level science and technology first prize and the provincial and ministerial level excellent engineering design. 7 awards.
In recent years, China has for Enfield Minmetals, the color, Jinchuan, white silver, gold, Daye, Jiangxi Copper, Yunnan Copper, cloud tin, nickel and other guitar companies to provide products.
In the design or general contracting project of more than 50 non-ferrous smelting waste heat boilers completed by Enfei in China, more than 130 waste heat boilers have been put into operation, creating the “first†and “most†of many domestic and foreign non-ferrous metallurgical waste heat boilers. E.g:
※The world's first oxygen-rich top-blowing nickel smelting furnace waste heat boiler with the largest evaporation capacity (evaporation capacity 160 tons / hour) - Jinchuan Nickel Smelting Project
※The world's first copper flash furnace waste heat boiler with the largest evaporation (evaporation capacity 116 tons / hour) - Jinchuan Fangchenggang copper smelting project
※The world's first zinc leaching slag melting furnace waste heat boiler with the largest evaporation (evaporation capacity 161 tons / hour) - Xiwuqi zinc smelting project
※The world's first high temperature superheated steam boiler - Laibin Huaxi zinc smelting project
※ the world's largest 152 square meters roaster waste heat boiler - Northwest lead zinc smelter
※The first natural circulation + forced circulation top-blown melting furnace waste heat boiler in China - Chuxiong Yuzhong Nonferrous Metals Responsibility Company
※ China's first bottom-blow electric smelting reduction furnace waste heat boiler - Anyang City Lushan Lead Smelting Technology Reform Project
※China's largest oxygen bottom blowing furnace lead-free waste heat boiler - Jiyuan Jinli lead smelting project
※The first domestic redox integrated furnace smelting and regenerative lead waste heat boiler——Low-temperature continuous smelting project of Hubei Jinyang waste lead-acid battery
※The first domestic transformation of the boiler introduced by Kawasaki, Japan - Northwest Lead and Zinc Smelter
※The first domestic transformation of the boiler introduced by Foster Wheeler in the United States - Tongling Jinchang Smelter
China Enfei also exported waste heat boilers and supporting technologies to more than 10 countries including India, Pakistan, Zambia, Congo (DRC), Congo (Brazzaville), Myanmar, Vietnam, Papua New Guinea, etc., which has achieved good economic benefits for enterprises. Environmental and social benefits have fully demonstrated China's national responsibility to fully explore overseas markets under the guidance of the “Belt and Road†strategy.
At present, the five development concepts of innovation, coordination, green, openness and sharing have become an important direction for industry and the whole society to focus on exploration. With the goal of sustainable development of the industry, China Enfi will continue to promote the research and development of waste heat boiler equipment and related technologies. The non-ferrous industry and even more energy-saving and environmental protection industries have continued to contribute to resource conservation and environmentally friendly goals.
