During boiler operation, the centrifugal blower fan plays a crucial role in expelling combustion exhaust gases and replacing them with sufficient oxygen. Therefore, damage to the centrifugal blower fan will lead to incomplete combustion of the fuel gas, severely impacting the safe, efficient, and low-NOx operation of the wall-hung boiler.
Traditional boiler fans are located at the exhaust port of the balanced flue. Moist flue gas, exceeding 200°C and containing corrosive gases such as hydrogen sulfide, is directly drawn out by the centrifugal blower fan, making the centrifugal fan and blower blades easily eroded, increasing the likelihood of boiler fan malfunctions.
In contrast, Foshan Shunde Nianxun Electric Appliance CO., LTD.'s centrifugal blowers are installed on the fresh air duct. The balanced flue system uses a technology that draws in fresh air and blows it into the boiler, giving the centrifugal blowers the advantage of operating at ambient temperatures. Therefore, compared to traditional centrifugal blowers, the blowers used in our boiler fan balanced flue system have a significantly longer lifespan.
Centrifugal blowers offer energy-saving and environmentally friendly combustion. A fixed initial volume of cold air expands significantly after being heated to hot air. Therefore, for the same initial volume, a standard centrifugal blower directly extracts hot flue gas, consuming far more power than our centrifugal blower fan (for cold air). Thus, using our centrifugal blower fan offers energy savings.
Centrifugal blowers provide more stable and comfortable operation. Centrifugal blowers offer superior resistance to headwinds. EU standards require balanced flues to withstand wind speeds of 30-45 km/h. Our centrifugal blower fan's balanced flue can withstand wind speeds exceeding 60 km/h, ensuring safe and stable operation of the gas-fired boiler.
