DINKONDA GLOBAL Power Plants Special 4-73 Series High-temperature Dusty Flue Gas Special Boiler Induced Draft Fan, Boiler Thermal System Auxiliary Equipment

Product Overview

The 4-73 series boiler induced draft fan is the core auxiliary equipment of the boiler thermal system, suitable for use with various industrial boilers. This fan is developed based on a mature 4-73 centrifugal fan aerodynamic model, mainly responsible for boiler system flue gas suction and furnace pressure regulation. Through stable airflow organization, it ensures full combustion of boiler fuel and completes the transportation and emission of flue gas. It is widely used in industrial boiler scenarios such as heating, chemical, and building materials, and is a key equipment to ensure continuous, safe, and efficient operation of boilers.

Structural Composition

1. * * Spiral shell * *: Made of thickened steel plates welded together, the shell has strong rigidity and resistance to high-temperature flue gas erosion. The flow channel is optimized by aerodynamics to reduce airflow loss; Reserved maintenance window on the shell for easy inspection of the impeller and cleaning of accumulated dust.

2. * * Impeller component * *: adopts a backward inclined blade structure, undergoes high-precision dynamic balance correction, and has low operating vibration; Wear resistant materials can be selected according to the dusty conditions of the flue gas, which can withstand the wear of smoke particles and are suitable for long-term continuous operation.

3. * * Bearing box assembly * *: Heavy duty oil lubricated bearing seat with high load-bearing capacity and excellent heat dissipation performance, which can resist the temperature rise caused by smoke conduction and ensure long-term uninterrupted operation.

4. * * Transmission System * *: Belt transmission structure, equipped with safety protection cover, stable transmission, can flexibly adjust the fan speed by replacing the belt pulley, and adapt to different load conditions of the boiler.

5. * * Drive motor * *: Equipped with industrial three-phase asynchronous motor, high protection level, suitable for high-temperature and dusty on-site environment in boiler rooms.

6. * * Integrated Base * *: A steel welded integral base with stable structure, effectively suppressing unit vibration, and facilitating the lifting and positioning of the entire machine.

Product Advantages

1. * * Ensure full combustion of fuel and improve thermal efficiency**
The induced draft fan, in conjunction with the air supply system, creates a complete airflow cycle, maintains a reasonable negative pressure in the furnace, ensures smooth entry of combustion air into the furnace, allows fuel and oxygen to be fully mixed, achieves complete combustion, improves boiler heat utilization efficiency, and reduces fuel waste.

2. * * Stable combustion conditions to reduce pollutant generation**
It can cooperate with the system to adjust the flue gas flow rate, stabilize the combustion state of the furnace, and avoid problems such as incomplete combustion and furnace coking. Adequate combustion can significantly reduce the generation of pollutants such as carbon monoxide and carbon black, meeting environmental emission requirements.

3. Timely exhaust of flue gas and optimization of furnace combustion environment**
Continuously extracting high-temperature flue gas and exhaust gas generated by boiler combustion, timely removing dust and harmful components from the flue gas, maintaining a good combustion environment inside the furnace, reducing the erosion of high-temperature smoke and dust on the heating surface of the boiler body, extending the service life of the boiler body, and assisting enterprises in green production.

4. * * Regulating furnace pressure to improve boiler operation safety**
Accurately maintain negative pressure in the furnace to avoid the risk of positive pressure tempering and flame spraying; Quickly discharge the accumulated combustible and harmful gases in the furnace, reduce the safety hazards of explosion and poisoning, stabilize the furnace pressure and temperature, and ensure the safe and reliable operation of the entire boiler system.

5. * * Efficient and energy-saving design, reducing long-term operating costs**
The fan adopts mature pneumatic design, with high operating efficiency. Combined with variable frequency regulation, the operating parameters can be dynamically adjusted according to the boiler load, reducing power loss under no-load and low load conditions, effectively reducing the energy consumption of the boiler system, and helping enterprises achieve energy conservation, emission reduction, and sustainable production.
