a Large-sized Special-steel Blast Furnace Blower System

 

In Phase I project of a large special steel manufacturer in eastern China, a 550 m3 iron-smelting blast furnace was built mainly to provide special steel for many heavy machinery enterprises. Since 2009, it has performed the feasibility study on the frequency converter renovation of its blast furnace blowers. In 2010, the solution was finalized through public bidding to carry out the energy saving renovation of its frequency converters with the ZINVERT HV variable frequency speed control system. The model of such blast furnace blower was 30JK100. It was the all-over-controlled-vortex 3D impeller centrifugal compressor. Its motor was 10 kV and 7800 kW. The supporting frequency conversion device was ZINVERT-A10H10000/10Y HV variable frequency speed control system.

After completion of installation and debugging, such HV variable frequency speed control system was given the related interactive debugging and other special tests. Its performance indicators fully met expectations. Consequently, this project was put into operation successfully in 2010. Its operation in two years showed stable equipment operation, excellent performance and significant energy saving result. The total electric power saved was approx. 30,000,000 kWh. Therefore, this project has greatly contributed to the energy conservation and efficiency improvement of its owner.
