The biggest difference between biomass boilers and coal boilers is the difference in fuel.
Biomass is a renewable resource, while coal is a non-renewable resource .
No matter how abundant coal resources are, they will eventually run out. Therefore, from the point of view of choosing a boiler, it is more recommended to choose a biomass boiler.
Biomass fuels are also divided into several types, such as biomass briquettes (biomass briquettes, biomass pellets) and straw bale direct combustion fuels.
As shown below:
Biomass pellets (straw pellets)
Biomass briquettes (straw briquettes)
Round Straw Packs
Straw Square Pack
The choice of biomass boiler to burn depends on the abundant resources in your area.
For example, the NoEast, Shandong, Henan and Anhui have relatively abundant straw resources. You may want to consider direct-fired boilers fueled by straw bales. The cost of fuel is very low. The straw is packaged directly from the field and does not require secondary processing like biomass briquette fuel. The cost of fuel is about 60% lower than coal. In Heilongjiang, this technology is relatively mature and environmentally friendly.
For places where straw resources are relatively scarce but forest resources are relatively rich and there are local biomass briquette processing factories, you can also choose biomass briquette fuels . The advantage is that it is clean and practical. but the disadvantage is that the cost is relatively high. After all, it requires many processing steps(raw material crushing, crushing, drying, shaping, cooling and packaging, etc.).
