Description
Centrifugal induced draft fans and blowers
The fan is used for the fan and induced draft fan system of 2-670t / h steam boiler in thermal power plant.
The medium conveyed by the fan via air, and the maximum temperature must not exceed 80 °C. Medium conveyed by the induced draft fan is flue gas. And the highest temperature must not exceed 250 °C. Before the induced draft fan, a dust removal device with a dust removal efficiency of not less than 85% must be added to reduce the dust content of the flue gas entering the fan. Increase the life of the fan.
The ventilator (G) and the induced draft fan (Y9) are single air intake air intakes, with № 8, 10, 11.2, 12.5, 14, 16 There are seven types of machines, all of which are D-type. Each fan can be made in two directions: forward (right) or reverse (left) This type, face the fan from one end of the motor. An impeller that rotates clockwise is called a right-handed fan, and the impeller rotates counterclockwise. The direction of rotation is called a left-hand fan. The outlet position of the fan, is expressed by the angle of the air outlet of the casing. “Left” and “right” rotary fans can be made 0° 45°90 There are six fixed angles of °, 135° 180° and 225°.
