The main function of boiler induced draft fan is to extract boiler flue gas, maintain boiler negative pressure, and ensure smooth operation of combustion system
1. Maintain boiler negative pressure
When the boiler is running, it is necessary to maintain a certain pressure in the furnace. The boiler induced draft fan extracts the flue gas in the boiler by generating a strong airflow to maintain the negative pressure state in the furnace. The induced draft fan can accurately control the pressure in the furnace by adjusting its speed and air volume to prevent the furnace from exploding due to excessive pressure or causing a large amount of external cold air to enter due to low pressure, affecting the combustion efficiency.
2. Promote flue gas purification
When the flue gas flows through the dust collector, air preheater and other equipment, pressure loss will occur. The induced draft fan can overcome these pressure losses and discharge the flue gas smoothly. The smooth discharge of flue gas is crucial to maintaining the normal operation of the combustion system. The induced draft fan can stably send the flue gas into the desulfurization system or directly discharge it into the chimney, ensuring the smooth operation of the combustion system.
3. Improve combustion efficiency
Promote full combustion of fuel: One of the functions of the induced draft fan is to enable the flue gas generated in the furnace to be discharged smoothly from the furnace by overcoming the pressure loss of the tail flue, dust collector, air preheater, etc. Such a process helps to improve economic benefits, because effective flue gas emission helps to improve the thermal efficiency of the boiler and reduce energy consumption.
Optimize flue gas emission: Maintaining sufficient negative pressure in the furnace can ensure sufficient oxygen supply to allow the fuel to be fully burned. Doing so can not only maximize the use of energy and reduce waste, but also reduce the emission of pollutants, which has a positive impact on environmental protection.
