Rank of domestic flue gas desulfurization enterprises
(1) Long Yuan Environmental Protection (Guodian Power) introduced the wet limestone-gypsum desulfurization technology from the German company Sota Miller. The company has participated in many Sino-foreign cooperation demonstration projects, such as Sino-Japanese cooperation between Shandong Huangdao Power Plant and Taiyuan No.1 Thermal Power Plant, Sino-German cooperation between Chongqing Power Plant and Zhejiang Banshan Power Plant and Yunnan Xiaolongtan Power Plant, and is in a relatively leading position in the field of desulfurization. Long Yuan Environmental Protection Co., Ltd. contracted the desulfurization reconstruction project of No.4 boiler (200MW) of Beijing Jingneng Thermal Power Co., Ltd. in June, 20065438+0, which was the first time that the company contracted the desulfurization project completely independently.
(2) Zhejiang Feida is a key enterprise in the field of electrostatic precipitator. The company invested more than 30 million yuan to introduce ABB's charged dry flue gas desulfurization (NID) method from Sweden, and completed the desulfurization project of a medium-sized unit (70MW unit in the self-provided power plant of Zhejiang Juzhou Chemical Company), which is running well at present. Because the company has many years of experience in the field of flue gas treatment, and the company has made rapid progress in the field of flue gas desulfurization, it has strong comprehensive competitiveness in this field.
(3) Longjing Environmental Protection is a key backbone enterprise in China environmental protection industry, ranking among the top ten in electrostatic precipitator industry, and has rich experience in flue gas treatment (dust removal). Longjing Environmental Protection plans to invest 62.4 billion yuan in flue gas desulfurization industry with new shares 1. At present, the technical partner is American GE Company. Longjing Company and China Energy Saving Investment Company jointly invested to establish Longyan Longjing Desulfurization Engineering Co., Ltd., with a registered capital of 39.6 million yuan, and the company's shareholding ratio is 80%. Longjing desulfurization company is mainly engaged in the design and manufacture of desulfurization and dust removal equipment, consulting services and engineering contracting business, and undertakes the localization project of flue gas dust removal and desulfurization device in coal-fired power stations with special funds of 1999 national debt. Longjing environmental protection is still in the initial stage of introducing flue gas desulfurization technology.
(4) Katie Electric Power Company invested 49 million yuan to introduce RCFB-FGB dry flue gas desulfurization technology from Germany WULL Company, and produced a desulfurization device matched with a single power station boiler below 300,000 kilowatts. It has the first rotary spray drying flue gas desulfurization test device with all independent intellectual property rights in China. On July 6th, 2000, Wuhan Flue Gas Desulfurization and Environmental Protection Industrial Base, which was jointly established by Katie Power and other six units, was formally established. At present, it is announced that it plans to issue new shares to introduce wet desulfurization technology, which will expand the scope of the company to undertake flue gas desulfurization.
(5) Kowloon Electric Power is mainly engaged in power production and power technical services. The company entered the flue gas desulfurization industry through holding Chongqing Yuanda Environmental Protection (Group) Co., Ltd. (registered capital of 50 million yuan) by raising funds from new shares, and adopted the limestone-gypsum wet desulfurization technology of Mitsubishi Heavy Industries of Japan, and will organize the implementation of the total investment (total investment [1999] 1297)1500 million yuan issued by the State Planning Commission.
(6) Tsinghua Tongfang Company owns independent intellectual property rights of dry circulating fluidized bed flue gas desulfurization technology, which is suitable for units below 300MW, and is currently being applied to the flue gas desulfurization demonstration project of Tsinghua University Experimental Power Plant. The company has also developed the integrated technology of liquid column jet flue gas desulfurization and dust removal, which is currently applied to the flue gas desulfurization demonstration project of Shenyang Chemical Fertilizer General Plant. After three months of debugging and operation, it has passed the appraisal of relevant departments.
