High Temperature Boiler Centrifugal Fan for Drying and Industrial Ventilation

Introduction

Industrial boilers, drying systems and ventilation equipment require stable airflow under demanding operating conditions.

SIMO 5-06 series centrifugal fans are designed for boiler air supply, induced draft, material drying, dust removal and general industrial ventilation.

The fan uses a single-inlet structure and backward-curved impeller, with 16Mn high-strength steel available for demanding applications. It can be configured according to airflow, pressure, temperature and installation conditions.

For induced-draft applications, the maximum operating temperature specified for this series is 250°C.

Technical data

Product Features

High Temperature Air Handling

The fan is designed for applications involving heated air and flue gas.

Suitable for:

• Boiler ventilation
• Material drying
• Hot air circulation
• Industrial exhaust

16Mn High-Strength Construction

16Mn steel can be selected where higher structural strength is required.

Material selection can be adjusted according to:

• Operating temperature
• Dust concentration
• Wear conditions
• Gas characteristics

Backward-Curved Impeller

The backward-curved impeller is designed to provide stable airflow and pressure performance.

It helps support:

• Smooth operation
• Lower vibration
• Reliable continuous running
• Efficient air delivery

Flexible Airflow Adjustment

Airflow and pressure can be adjusted through the fan damper.

A variable frequency drive can also be used where speed-based airflow control is required.

Bearing Cooling for High Temperature Applications

Depending on the operating conditions, bearing cooling can be configured with:

• Water cooling
• Oil cooling
• Additional cooling equipment for demanding conditions

This helps maintain reliable bearing operation under elevated temperatures.

FAQ

1.What is a high temperature boiler centrifugal fan?

It is a centrifugal fan designed to supply or exhaust air and gas in boiler systems where elevated temperatures require suitable fan materials, cooling and structural design.

2.What is this 16Mn fan used for?

This 5-06 series fan can be used for boiler ventilation, induced draft, material drying, dust removal, mine ventilation and general industrial ventilation.

3.What is the maximum operating temperature?

For the induced-draft application described on this product page, the maximum operating temperature is 250°C. Higher-temperature applications require a different fan configuration and cooling design.

4.Can this fan be used for material drying?

Yes. The fan can provide hot-air circulation and airflow for industrial drying systems. Final selection should be based on the required airflow, pressure and temperature.

5.How do I select a boiler centrifugal fan?

Provide the required airflow, pressure, inlet temperature, gas characteristics, voltage and installation conditions. SIMO engineers can then recommend the appropriate fan configuration.
