Industrial CFB Boiler Explosion Protection Induced Draft Blower Fan
Introduction
The Industrial CFB Boiler Explosion Protection Induced Draft Blower
Fan is designed to work in the high efficiency area to achieve
energy saving when operating under variable operating conditions.
It is jointly designed by the fan energy-saving group of the
Ministry of Machinery Industry and organized by the national fan
industry.
It’s a high-performance product promoted by the State Economic
Commission and the Ministry of Machinery Industry.
Industrial CFB Boiler Explosion Protection Induced Draft Blower Fan
has the advantages of high efficiency, low noise, wide performance
and high efficiency curve.
Applicable to industrial boilers of 5 ~ 35 tons/hour, the similar
intake conditions and performance can be adapted, but the maximum
temperature should not exceed 250 °C.
The dust removal device with a dust removal efficiency of not less
than 85% must be installed before the induced draft fan, in order
to reduce the dust content of the flue gas entering the fan, which
not only reduces the pollution of the flue gas to the environment,
but also reduces the wear of the dust on the fan. It’s conducive to
extending the life of the fan.

Advantages and Features
1. It is capable of outputting higher gas pressures and providing
more gas flow with lower noise.
2. In the case of common base, the installation is very simple and
requires little support from a professional technician.
3. The motor shaft is elastically connected with the drive shaft,
and it is not necessary to constantly tighten the belt or replace
the belt, and the maintenance workload is small.
4. Fans with an impeller diameter of less than 1400 mm operate at a
normal temperature fan system, eliminating the need for additional
bearing cooling devices, reducing the amount of user investment and
maintenance.
5. When the airflow resistance is increased, the motor load will be
automatically reduced and the motor will not be burnt.
6. It is made of high quality carbon steel, stainless steel or
other metal materials are available upon request.
7. After the production is completed, after running test and
vibration value detection, the operation is reliable.
FAQ
1. What parameters need to be provided when you design the
industrial centrifugal fans?
Answers: Air flow, total pressure or static pressure, inlet
temperature, local voltage and frequency, Altitude etc.
If there is flammable and explosive gas, or big dust loading in the
medium, please also inform the designer.
2. How about your company’s pre-sales service and after-sales
service?
Answers: Before our cooperation, we have the professional technical
team to help you make the technical solution according to your
working condition, to make sure the centrifugal fan efficiency
operation.
After sales service, we will offer 12 months’ repairing service,
and provide lifelong follow-up services. Besides, our engineers are
available for going abroad to offer the repairing service.
3. Does your company have qualifications?
Answers: SIMO Blower has obtained ISO 9001-2008, CE, BV
certifications and so on.
