Stainless Steel Single Suction CFB Boiler Induced Draft Blower Fan
Introduction
At present, there are many series of boilers, and the situation of
burning coal quality is quite different, after installing dust
removal equipment and waste heat utilization equipment,
insufficient pumping force affects normal operation.
In order to overcome the insufficient pumping force due to the
above reasons, the furnace has a positive pressure, which affects
the combustion and normal operation of the boiler.
Therefore, various types of boiler induced draft fans have been
designed and manufactured for the design and manufacture of air
volume, wind pressure and boiler matching efficiency. Provide each
user to choose an application.

Advantages and Features
1.The fan pressure is high, therefore it is especially suitable for
1-20t/h industrial boilers, which equipped with spiral pipes and
multi-tube dust collector.
2.The induced draft fan is made into a single suction, different
impeller diameter from 400mm to 3000mm.
3.The position of the air outlet of the fan is expressed by the
angle of the air outlet of the casing."Left" and "Right" can be
made into different angles.
4.Fan drive mode is V-belt drive, coupling drive, double support
type.
5.The fan has high efficiency, high total pressure, low noise, flat
performance curve, wide economical use area, and adopts backward
plate type blades. The efficiency of the fan at the best working
point is 86.5%, and the noise index( than A sound Level) is
Ls=11.5dB.
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
