Feasibility Study on the Boiler Induced Draft Fan Energy Saving Frequency Conversion Retrofit

Abstract:

Aiming at the badly needed goal of energy saving, the retrofit is implemented by adopting the stepless speed regulation of motor driving by the high-voltage inverter to regulate the air quantity. The inverter is taken its character of easy manipulation, small maintenance, high control precision as the advantage to replace the traditional device like air door operated and wind deflector operated methods. Furthermore, the feasibility analysis for the energy-saving effect after retrofit will be conducted. It has been concluded that there are obvious improvements both in energy saving and operational stability after the frequency conversion retrofit on the machine.
