Abstract: After installation of 5 000kV heater in oil transporting pipeline, evident result is get in energy saving. This kind of heater uses light furnace lining structure and has the advantage of promptly decreasing or rising of load. Pneumatic atomizing burner of external mixing and double air piping, with superior property, is used in the heater, which can make the operation stable. Compared with other heaters, the 5 000kV heater has the advantage of simple operation and convenient repairing. Furthermore, combining with computer control system makes it more safety and reliable. The article points out the disadvantages existed in automatic control system as instrument, software and control plan of the 5 000kV heater and puts forward improving measures. The heater has been used for commissioning in the pumping stations of Liao Cheng, Lin Yi and Ji Ning over Lu Ning pipeline for more than three years and shown a good technical status.
