Jinxi Iron ＆ Steel PCBB Optimal Control Of Blast Furnace Blower

Blast furnace blower is the most important power equipment, it not only provides the oxygen required for blast furnace, but also provides the resistance needed to overcome the high burden of gas power column is the control of blast furnace gas exchange critical lifeline facilities. The proposed PCBB (Professional Control For Blast furnace blower) optimal control, also known as Integrated optimal control of blast furnace blower. Based on the use technological means to improve air blower pressure, speed up the pace of blast furnace production, improve iron production is the main purpose; reduce the venting flow, to achieve energy saving automatic control system for the secondary purpose of the comprehensive optimization improvements. Based on the # 7 Jinxi Axial Fan PCBB optimal control, air blower from the blast furnace process started, layer by layer depth and detail of the blast furnace blast furnace blower effect, fans surge production, effects and solutions Road. Research mainly focuses on the system fan control algorithm optimization and improvement of anti-asthma, do not change the hardware on the equipment, focusing on anti-surge line of the fan described the development of principles and how to achieve energy efficiency goals. Fan end of the study and put into operation, the fan performance significantly, with steady running, energy-saving effect is remarkable. # 7 of fans after 30 days of observation compared with the same type of fans, tons of iron reducing power consumption an average of 6.07 degrees, the monthly saving electricity 28 million, the intended design goals. The success that the fan without changing the overall structure, because the control methods, its overall performance is variable, and fans can not only simplify the optimization of integrated control of the producer's methods of operation, its more important role is the use of automated speed control response quickly, the advantages of high accuracy make up for lack of manual control, to achieve a fundamental change in fan control.
