ideal classic boiler fan

ideal classic boiler fan

This ideal classic boiler fan is mainly used for 2~670 t / h steam boilers and mine ventilation in thermal power plants. The medium treated by the fan is air, and the maximum temperature generally does not exceed 80 °C; the medium treated by the induced draft fan is flue gas, and the maximum temperature generally does not exceed 250 °C. A dust control device must be added to the front of the induced draft fan to reduce the dust content of the flue gas entering the fan. According to the operation of the general power station, the efficiency of adding the dust collector is not less than 85%.
Product description

Product introduction:

This ideal classic boiler fan is mainly used for 2~670 t / h steam boilers and mine ventilation in thermal power plants. The medium treated by the fan is air, and the maximum temperature generally does not exceed 80 °C; the medium treated by the induced draft fan is flue gas, and the maximum temperature generally does not exceed 250 °C. A dust control device must be added to the front of the induced draft fan to reduce the dust content of the flue gas entering the fan. According to the operation of the general power station, the efficiency of adding the dust collector is not less than 85%.

Product features:

1. The induced draft fan is a single suction fan with 13 fan numbers. The exit position of the ideal classic boiler fan can be indicated from the exit angle of the housing. The fan drive is D-type and is connected by a flexible coupling. The fan is mainly composed of an impeller, a casing, an air inlet, a damper and a driving device.

2. The impeller is welded between the conical cover and the flat disc by 12 rear wing blades. The fins used are high in efficiency, low in noise and high in strength, so that the impeller can be operated smoothly. For the same fan No fan and induced draft fan impeller, the structure is the same, but the material is different, the fan is generally selected A3, and the induced draft fan is 16Mn.

3. The casing of ideal classic boiler fan is welded into a volute by ordinary steel plates. There are three different types of single suction fan housings. The No8~12 housing is integral and cannot be disassembled. The No14~16 housing is double-open, and the No18~29.5 housing is three-open. For induced draft fans, use a thicker rotating plate to prevent wear.

4. The drive part of the main shaft is made of super steel, and the fan adopts rolling bearing. There are two types of bearing housings. There is a thermometer and oil indicator on the bearing box. 30# mechanical oil is used for lubrication. The oil filling amount should be the same. If the integral bearing housing uses dry oil, the oil retaining plate should be added on the ball side of the bearing housing. The fixing groove is pre-installed. . The induced draft fan has a cooling water unit.
