Abstract: The necessity of reducing the plant power consumption of 300MW CFB unit was analyzed. Some methods for reducing the house power consumption were introduced from aspects of management, technical reformation and operation mode optimization respectively. The technical difficult problems of the higher auxiliary power consumption rate in 300MW CFB unit were solved, and this is advantageous to the upsizing of CFB boiler capacity and its development in our country.

Key words: CFB unit, house power consumption, technique measurement
