Its products can meet the most stringent emission standards at present. In the No.2 Steel-making Plant Tertiary Dedusting and Secondary Dedusting System Upgrade Project of Anyang Iron and Steel Group, CERI has adopted advanced design concept combined with its comprehensive treatment technologies of iron and steel production, optimized the layout, and reduced operation and investment cost. The emission index meets the China ultra-low emission standard, which is at the leading level in China. The Project won the 2020 Metallurgical Industry Excellent Engineering Design Award.
Converter Gas Dry Electrostatic Precipitator Product
Since the first converter gas purification and recovery system introduced into China by CERI in 1994 was applied in Baosteel, CERI has undertaken the design and general contracting of more than 50 sets of converter gas dry purification systems, with a market share of more than one third in China. The A/B/C Converters Primary Dedusting Upgrade Project of Ansteel No.4 Branch uses CERI’s self-developed ultra-clean cooling demister as the core, which solves the problems usually seen in the conventional dry dedusting, such as unstable collection efficiency of dust of high specific resistance and ultra-fine particle dust escape, and reduces the dust concentration to 10mg/Nm³. This technology is at the internationally leading level.
Blast Furnace Gas Dry Bag Filter Product
CERI has independently developed the patented large-scale blast furnace gas dry bag filter products, with specifications of DN4000mm, DN5200mm, DN6000mm and other series, and supporting blast furnaces ranging from 1,000m³ to 6,000m³. The bag filter has the gas flow stably in and out from the top. Its filter bag has long service life and high filter efficiency, with maximum size up toφ 160mm × 8,000mm. Its equipment occupies a small area, and the maintenance work load is reduced by about 30% compared with conventional filter equipment. Its valves are arranged on the top of the frame structure, which is good for ventilation and convenient for maintenance. The operation indexes of the filter system have reached the internationally leading level. The Dry Bag Filter Project of Guangyang No. 1 Blast Furnace in POSCO, Korea contracted by CERI is currently the largest dry filter system of blast furnace gas in the world. With CERI’s patented technology of the top-in top-out bag filter, its emission measured during the operation is 1~2mg/Nm³. The Project won the 2015 Metallurgical Industry Excellent Engineering Design Award and the 2016 Industry Excellent Project General Contracting Award.
High-efficiency and Long-life Converter Flue Gas Heat Recovery Package Technology
It has won six provincial/ministerial awards in China. During the development of this technology, CERI has comprehensively overcome many technical difficulties such as system energy saving, poor heat recovery effect, equipment energy waste, high failure rate, short service life, etc. This technical breakthrough to have high-efficiency and long-life equipment has been widely used in large and medium-sized iron and steel enterprises in China, and its market share accounts for over 60% in China, with remarkable economic and social benefits.
Fujian Sanming 80MW Coke Oven High-temperature and Ultra-high-pressure Waste Heat Recovery and Power Generation Project
On December 16, 2020, CCTV News Broadcast covered a special report of this Project, which is the first high-temperature and ultra-high-pressure waste heat power generation system based on header system in China. It could realize the maintenance and repair of steam turbine without shutdown of coke oven. It is an important part of full energy recovery, clean and environment-friendly coke-making project, and greatly improves the self power generation rate of the steel plant, making outstanding contributions to energy saving, emission reduction and green development of the enterprise. This Project has become a reference model for the design of many similar systems in China.
80MW High-temperature and Ultra-high-pressure Gas Power Generation and Energy-saving Upgrade Project of of Henan Jiyuan Iron and Steel (Group ) Co., Ltd.
The Project won the Special Recognition Award of 2019 Year in Infrastructure Awards. With this Project, CERI has made the precedent of using BIM technology in the field of power generation project and promoted the popularization and innovative application of BIM technology. Using the surplus gas in the plant area to generate electricity efficiently, the Project takes the lead in realizing the synchronous construction of gas power generation and ultra-low flue gas emission, and has obvious economic and environmental benefits.
