Biomass Fired Furnace/Boiler. Biomass Fired Furnace/Boiler Overview: The biomass fired furnace or boiler is a device that burns biomass fuel to produce heat for electricity generation or industrial processes. 1. Process: - Biomass is fed into the furnace or boiler where it is burned to produce heat. - The combustion process involves high temperatures (typically 800-1,000°C) to release thermal energy. - Heat is transferred to water or air to produce steam or hot air, which is used in power generation or heating. 2. Fuel Characteristics: - Biomass fuels used in these boilers include wood chips, agricultural residues (e.g., rice straw), and dedicated energy crops. - Characteristics such as calorific value, moisture content, ash content, and bulk density influence combustion efficiency..
Scene 14 (2m 32s)
3. Fuel Types: - Wood-based fuels: Wood chips, wood pellets, sawdust. - Agricultural residues: Rice straw, wheat straw, corn stover. - Energy crops: Miscanthus, switchgrass, and fast-growing trees. 4. Air-Fuel Ratio: - The air-fuel ratio is critical for efficient combustion. - It must be balanced to ensure complete combustion, minimize emissions, and maximize heat production. - Typically, the air-fuel ratio is 4:1 to 6:1 for biomass furnaces. 5. Other Aspects: - Combustion Efficiency: Optimized by controlling fuel particle size and moisture content. - Ash Management: Ash produced by burning biomass needs to be removed periodically. - Environmental Impact: Biomass boilers can be carbon-neutral if managed properly.
