CIE signed a retrofit contract on main suction fan frequency conversion and energy saving of Xinyu

2017/05/17

It was on May 12 that CIE signed a retrofit contract on main suction fan frequency conversion and energy saving of No.7 sintering machine with XIYU IRON & STEEL CO., LTD.

The No. 7 sintering machine of XIYU covers an area of 360 square meters, which main suction fan system is composed of 2 main sintering fans. The fans are operated with the power frequency, softly started by water resistance, using inlet damper to adjust wind pressure of system to meet the requirements of negative pressure. The inlet damper of 2 main suction fans has an aperture between 60 to 90 degrees. The electric energy has huge loss producing blast capacity through throttle adjustment. Designed mainly adopting variable frequency speed regulation operation mode and relevant matching power source, refrigeration, lubrication and other devices based on the main suction fans, and adopted the main exhaust intelligence frequency conversion control technology independently developed by CIE, the original control system has been updated predicting that the saving power rate can reach over 14%.

The main exhaust intelligence frequency conversion control technology independently developed by CIE has been successfully used at Brazil AMM sintering, Baogang 2×500 square meters sintering, Zhongtian Iron and Steel 550 square meters sintering, Longgang 450 square meters sintering, Xinyu 360 square meters sintering, Guangxi Shenglong 320 square meters sintering, Xinyu No. 8 sintering machine project with obvious variable frequency operation & energysaving effect and huge economic benefit & social value.
