Biomass-fired boilers can burn many fuel types, but they all belong to biomass energy, such as corn stalks, wheat straws, straws, peanut shells, corn cobs, cotton stalks, soybean stalks, weeds, branches, leaves, sawdust, bark and other solid waste of wood or furniture factories.
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.
1. The fuel volume is 1 / 30 ~ 40 of the raw material volume after molding;
2. The specific gravity is 10-15 times of the raw material, and the moisture content is between 12% and 18% (the moisture content of coal is below 10-15);
3. The net calorific value can reach 3500-4500 kcal (the net calorific value of class II bituminous coal is 3700-4700 kcal / kg);
4. The ash content is less than 10% (the ash content of coal is more than 20%);
5. Volatile matter ≥ 65.62% (volatile matter of class II bituminous coal≥20%).
6. Biomass fuel belongs to renewable clean energy, which is the same as wind energy and solar energy. The biomass fuel is rich in resources, it can ensure the sustainable use of energy.
7. The sulfur content and nitrogen content of biomass fuel are low, the amount of SOx and NOx generated in the combustion process is low.
Retrofitting a piece of equipment or an existing industrial heating system can be very challenging, but it can be especially frustrating if you haven't planned well ahead of time. You'll want to be sure that you've done your homework to ensure that retrofitting the piece of equipment you have in the way you have in mind is actually possible.
If it is possible, you'll want to work with the appropriate engineers to figure out exactly what it will entail, how much it will cost, what impact it will have on operations, etc.
Wood fuel has several environmental advantages compared with fossil fuels. Wood can be continually replenished, which leads to a sustainable and dependable supply. However, proper forest management must be practiced to ensure that growing conditions are not degraded during biomass production.
There is little net production of carbon dioxide from wood combustion, because the CO2 generated during combustion of wood equals the CO2 consumed during the lifecycle of the tree. Transporting the material using petroleum generates excess CO2.
