Primary Air Pulverized Coal Drying Grey Centrifugal Exhaust Fan

Introduction

The 9-11 series fan has a large flow rate and moderate pressure.

This fan is designed for the purpose of using industrial boiler to work in the high-efficiency area and achieve the energy-saving target.

The Primary Air Pulverized Coal Drying Grey Centrifugal Exhaust Fan is suitable for equipped with economizer (heater) and smoke and dust removal device.

It is a high-efficiency energy-saving product jointly designed by the national fan industry and organized by the national wind power industry and the Ministry of Machinery Industry.

It has the characteristics of high efficiency, low noise, flat performance curve and wide efficient area.

Industrial boilers of 5 ~ 35 tons/hour can be used, those with similar intake conditions and suitable performance can be used, but the maximum temperature shall not more than250°C.

Before the induced draft fan, dust removal device with a dust removal efficiency of no less than 85% must be installed to reduce the dust content of the smoke entering the fan.

It can not only reduce the pollution of the smoke on the environment, but also reduce the wear of the smoke on the fan, which is conducive to prolonging the life of the fan.

Application

1. As a device with good performance, centrifugal fans are now widely used for ventilation, dust exhaust and cooling in factories, mines, tunnels, cooling towers, vehicles, ships and buildings. The role of centrifugal fans is powerful. When users choose to use them, they also need to start from the characteristics of centrifugal fans and use them in a scientific way to ensure that the fans bring greater benefits to themselves.

2. In the factory, the workshops, warehouses and other departments are equipped with centrifugal fans, which play a role in ventilation, ensure the fresh air in the workshop, and help to purify the working environment and the health of employees. At the same time, the factory warehouse is equipped with centrifugal fans to dry the air to ensure that the mechanical equipment or other industrial products maintain the original quality.

3. Install centrifugal fans in mines and tunnels to re-enter fresh air and exhaust dirty air to ensure air circulation in the mines and tunnels.Centrifugal fans can help dust discharge, ensure air transparency in mines and tunnels, and ensure the health of workers in mines and tunnels.

4. A centrifugal fan is installed in the cooling tower, which not only plays the role of ventilation and ensures the normal operation of the cooling tower, but also plays a positive role in improving the cooling effect of the cooling tower by the large flow wind generated by the centrifugal fan.

Product features

1.The fan can output higher gas pressure, and can provide more gas flow at the same time, low noise.

2. In the case of using the common base, the installation is very simple and basically does not require the support of professional technicians.

3. The motor shaft is elastically connected with the drive shaft. It is not necessary to tighten the belt or replace the belt frequently, and the maintenance workload is small.

4. The fan system running at normal temperature with an impeller diameter of less than 1400 mm does not require additional configuration of bearing cooling device, which reduces the user's investment and maintenance workload.

5. When the airflow resistance is increased, the motor load will be automatically reduced and the motor will not be burnt.

6.The fan is made of high quality carbon steel, and can also use stainless steel or other metal materials according to customer requirements.

7. Running test and vibration value detection after the production is completed, the fan operation is reliable.
