High Pressure Explosion Proofing Industrial Boiler Centrifugal 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 fan is suitable for equipped with economizer (heater) and smoke
and dust removal device.
1. When the airflow resistance is increased, the motor load will be
automatically reduced and the motor will not be burnt.
2.The fan is made of high quality carbon steel, and can also use
stainless steel or other metal materials according to customer
requirements.
3. Running test and vibration value detection after the production
is completed, the fan operation is reliable.

Advantages and Features
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.
