What are some effective methods for controlling airflow in flue gas dust removal boiler fans?

There are many methods for controlling the airflow of flue gas dust removal boiler fans, and one of the most economical and effective approaches is to use system dampers. A system damper can essentially be viewed as a flow restrictor. The primary reasons for restricting airflow are pressure and energy losses, as well as noise, at specific points within the ventilation system. Additionally, adjusting the voltage of the flue gas and dust removal boiler fan is an effective method to maximize the fan’s efficiency. When connected to a transformer, the sine wave from the flue gas and dust removal boiler fan motor serves as a “clean” power input, thereby ensuring a stable output voltage for the motor. Furthermore, the voltage remains unaffected by electromagnetic noise or other harmonics. When selecting this method, we also find that its lower costs, weight, and required installation space are all reasonable. It can be said that its main advantages are low cost, light weight, and minimal space requirements. Furthermore, motors used in industrial applications do not have voltage control capabilities, and overheating generally depends on the type of centrifugal fan. Alternatively, we can also choose to integrate the electrical system with the motor. Although the inverter is somewhat cumbersome to handle, it can be successfully applied to the control of multi-speed, stepless-speed smoke and dust removal boiler fans. This not only saves energy but also reduces operating noise. For users, this control method imposes reasonable maintenance requirements in practical applications. It not only has low maintenance costs but also features standard overcurrent protection.
