DINKONDA GLOBAL Power Plants Special Boiler Combustion Fan, Boiler Ventilation Fan Induced Draft Fan, Core Air Supply Equipment For Boiler Combustion System

Product Overview

This boiler combustion fan belongs to the core air supply equipment of the boiler combustion system, designed specifically for supporting combustion air supply conditions in various industrial boilers. The product adopts a backward plate type blade aerodynamic structure, optimized through fluid dynamics simulation, and has the advantages of high total pressure, wide operating range, and low noise. The total pressure internal efficiency at the operating point can reach 86.5%, with a signal-to-noise ratio of Ls=11.5dB. The two core performance indicators are at the leading level among the same type of boiler ventilation and induced draft fans in China, stably delivering combustion air to the furnace, ensuring full combustion of fuel, and reducing boiler energy consumption and flue gas pollutant emissions.

Structural Composition

1. * * Spiral shell * *: The steel plate is welded together as a whole, with streamlined spiral flow channels to reduce airflow vortex losses. The shell has strong rigidity and can withstand air supply pressure; Reserved maintenance door on the shell for easy inspection and cleaning of internal impeller and dust accumulation.

2. * * Backward plate type impeller * *: The core working component adopts a backward plate blade structure, which has undergone precision dynamic balance correction and runs smoothly. The aerodynamic layout of the backward blades is the key to achieving high efficiency and a wide economic operating range.

3. * * Bearing box components * *: heavy-duty support bearing seat, reliable lubrication system, strong load-bearing capacity, good heat dissipation performance, can operate continuously and stably for a long time, effectively suppressing vibration transmission.

4. * * Belt Transmission System * *: The belt pulley transmission structure is equipped with a yellow safety shield on the outside for reliable protection, making it easy to adjust the speed on site and flexibly adapt to the air volume and pressure requirements of the boiler under different loads.

5. * * Integrated Base * *: The steel welded integral base has a stable structure, reduces the vibration of the unit operation, facilitates the lifting and positioning of the whole machine, and reduces the difficulty of on-site installation and commissioning.

6. * * Square air inlet and outlet * *: Square flange air outlet, easy to quickly connect with boiler air duct, sealed installation, reducing air supply leakage loss.

Product Features

1. * * Ultra high aerodynamic efficiency, outstanding energy-saving advantages**
Adopting backward plate blades, the total pressure internal efficiency at the operating point is as high as 86.5%. Compared with conventional boiler combustion fans, the motor power consumption is lower under the same air supply parameters. Long term continuous operation can significantly reduce the electricity cost of the boiler system.

2. * * High total pressure, wide range of adaptability to working conditions**
The whole machine has strong full pressure output capability, flat performance curve, and wide economic use area. When the boiler is adjusted in the low load, rated load, and overload range, the fluctuation of fan air volume is small, and there will be no sudden drop in performance due to changes in boiler load, adapting to the operation of the boiler under different working conditions.

3. * * Low noise aerodynamic design**
Optimization of pneumatic flow channels effectively suppresses airflow impact and vortex noise, with a sound level of 11.5 decibels higher than A sound level. The noise index is excellent, improving the working environment of the boiler room and making it easier to meet the environmental noise limit requirements of the factory area.

4. * * Stable operation and convenient maintenance**
The impeller has undergone strict dynamic balance verification, resulting in minimal vibration of the unit; The belt drive structure facilitates speed adjustment, and the maintenance port design facilitates regular inspection of impeller wear and dust accumulation, making operation and maintenance simple.

5. * * Strong universality**
It can be widely adapted to various industrial boilers such as coal-fired, biomass, and gas-fired boilers as combustion supporting air supply equipment. The same series of models can also be used for boiler ventilation and induced draft conditions, with performance indicators better than similar domestic industrial boiler induced draft fan products.
