How To Maintain The Fans Of Biomass Fuel Boiler
Majority of advanced biomass fuel boiler are equipped with a blower and a induced draft fan, because as a relatively energy-efficient boilers, the internal structure is more complex and the flue gas emissions are mostly with three return structure. So the blower and induced draft fan of biomass fuel boiler is necessary and vital to improving the combustion efficiency of fuel, which directly saves cost for industry.
Fans of biomass fired boiler
Boiler flue gas resistance is relatively large, natural ventilation chimney is difficult to stoke the furnace of fire. At this time, an external fan is needed to bring enough oxygen into the boiler combustion chamber so that the biomass particles within can be burned fully and more heat energy be provided. Meanwhile, high vertical chimney is not needed so you can effectively do the processing of dust emissions, but also to avoid the impact on the surrounding neighborhood and environment. But if the induced draft fan fails, the normal operation of the boiler will bring more trouble. As a high-speed rotating equipment, the induced draft fan will not only have to bear the sulfidation corrosion, but also heated by high-temperature of flue gas. So maintaining the fans is necessary for normal operation of boilers.
Maintenance of fans of biomass fuel boiler
1.If abnormal noise is generated when the fans is running, we should inspect and find out the reason
2.Observing whether there is abnormal vibration in fans, if so, we should find out the reason and stop the boiler to maintain in time to escape external accident
3.Often measure the fans with a multimeter at the motor voltage to ensure a stable value
4.Always check with a current meter to test whether the current is surpass the safety value
5.Often felt by hand to see if the motor has overheated
During the combustion process of biomass boilers, the main function of blower is to provide sufficient oxygen for biomass pellet burning, and the drawing fan is mainly to carry the energy to heat water. Maintaining regularly can effectively prevent the fan is damaged so the boiler can better serve for industry.
