Understanding the Combustion Process in Biomass Energy Generation

Understanding the Combustion Process in Biomass Energy Generation

This educational video by Bofu Academy, funded by the National Science Foundation and the US Department of Agriculture, provides a detailed overview of the biomass combustion process used for energy generation.

Step 1: Pre-Treatment of Biomass Feedstock

• Biomass feedstock is first dried, ground, and identified to prepare it for combustion.

Step 2: Combustion with Air Mixing

• The prepared biomass is combusted thoroughly with air in a combustor.
• Heat exchange occurs between hot air and cold water to optimize energy transfer.
• Some recycled solids are also burned during this stage to maximize fuel use.

Step 3: Steam Generation and Electricity Production

• Hot steam produced from combustion is sent to a steam turbine.
• The steam turbine generates electricity, converting thermal energy into electrical energy.

Step 4: Air and Solid Separation

• Hot air from the combustor passes through a cyclone separator.
• The cyclone removes solid particles suspended in the hot air, recycling them back to the combustor for further burning.

Step 5: Air Cleaning with Scrubber

• After solids removal, the air is treated in a scrubber.
• Water or reagent solutions in the scrubber remove dust, soluble toxic substances, and corrosive gases.
• This process ensures that the air released into the atmosphere is clean and environmentally safe.

Conclusion

• The video emphasizes the importance of each step in ensuring efficient biomass combustion and minimizing environmental impact.
• Viewers are encouraged to visit the Bofu Academy website for more educational resources.
