The biomass-fired boiler is a kind of equipment that uses the combustion of renewable energy biomass to provide heat energy for the boiler. The biomass-fired boilers are widely used especially by the enterprises located in the areas with abundant biomass fuel.
What are the reasons for the low efficiency of dust collector of the biomass-fired boiler? They are nature of dust, quality of bag and velocity of filtering.
With the continuous development of boiler manufacturing process and technology, fuel types of boiler have also increased, such as various combustible gases, fuel oil, biomass, coal and so on.
Biomass-fired boilers need to be shut down for maintenance. Proper maintenance can reduce the damage to the boiler caused by continuous work. Firstly, it is necessary to cut off all power to prevent being struck by lightning. In addition, dust, limescale and carbon deposits should be cleaned up to prevent rust and corrosion of the boiler.
Although biomass-fired boilers are environment-friendly boiler products, there are also some situations that biomass-fired boilers can’t be used. Main reasons as follows:
Fuel restrictions: The fuels that contain synthetic compounds can’t be used as the fuel of a biomass-fired boiler, such as waste wood furniture, waste paper, production and domestic waste.
1. If there is air in the pump or suction pipe, the air should be discharged.
2. If the depth of the bottom valve immersed in the water is not deep enough, the depth should be increased.
3. If the rotational speed is too slow or the conveyor belt is too loose, the rotational speed should be adjusted and the conveyor belt should be tightened.
4. If the impeller, suction pipe and bottom valve are blocked by dirt, you should check the pump body and clean the dirt.
5. If the height of water conveyance exceeds the regulations too much, the pump head should be adjusted to the specified range.
Firstly, the combustion of biomass fuel is easy to control. The fuel is easy to ignite. Besides, the combustion speed is faster than that of coal.
Secondly, the biomass-fired boiler can be ignited and extinguished at any time while the coal-fired boiler cannot. The biomass-fired boiler can also be ignited automatically.
Thirdly, the biomass-fired boiler can achieve zero emission of sulfur dioxide, which belongs to environment-friendly boilers.
The temperature of flue gas generated by a biomass-fired boiler is relatively high. But it is not corrosive. So, it is suitable to use heat resisting glass fiber needled felt bag which has a good use effect. Moreover, this kind of cloth bag is not very expensive.
