Gross Calorific Values of Biomass Materials with more information:

Gross Calorific Value (GCV) of various biomass materials, we can expand on the types of materials, factors affecting GCV, and typical uses:

1. Wood Pellets:

• Pine, Cedar, Spruce, Fir:
  • GCV: ≈ 4300-4500 kcal/kg
  • Factors Affecting GCV: Moisture content, resin levels, and density.
  • Typical Uses: Residential heating, industrial energy production, and as a feedstock in pellet stoves.
• Hardwood (Xylosma, Catalpa, Elm):
  • GCV: ≈ 4500 kcal/kg
  • Factors Affecting GCV: Hardwoods generally have higher energy density due to their denser structure.
  • Typical Uses: High-quality fuel for heating and power generation.
• Softwood (Poplar, Birch):
  • GCV: ≈ 4300 kcal/kg
  • Factors Affecting GCV: Softwoods often have lower GCV compared to hardwoods, partly due to their lower density.
  • Typical Uses: Similar to other softwoods, used in heating applications and power generation.

2. Crop Waste Pellets:

• Bean Stalk, Cotton Stalk, Peanut Shell:
  • GCV: ≈ 3800 kcal/kg
  • Factors Affecting GCV: Crop residues vary widely in energy content depending on plant type and residual nutrients.
  • Typical Uses: Often used in agricultural waste biomass plants or as a supplement in co-firing with other biomass types.
• Corn Stalk, Rape Shoot:
  • GCV: ≈ 3700 kcal/kg
  • Factors Affecting GCV: Stalks and shoots generally have lower energy density due to their fibrous content.
  • Typical Uses: Used in biomass power generation, often mixed with other biomass to improve burn quality.
• Wheat Straw:
  • GCV: ≈ 3500 kcal/kg
  • Factors Affecting GCV: Straw is generally low in energy density, and its calorific value can be affected by its high ash content.
  • Typical Uses: Used in rural areas for heating, and in industrial biomass boilers.
• Potato Straw:
  • GCV: ≈ 3400 kcal/kg
  • Factors Affecting GCV: Contains higher moisture content, which can lower the effective energy output.
  • Typical Uses: Sometimes used in combination with other biomass materials.
• Rice Straw:
  • GCV: ≈ 3200 kcal/kg
  • Factors Affecting GCV: High silica content can lead to lower energy output and higher ash production.
  • Typical Uses: Often used in biomass plants specifically designed to handle high ash content fuels.

3. Other Biomass Materials:

• Weed:
  • GCV: ≈ 3873 kcal/kg
  • Factors Affecting GCV: The energy content can vary widely depending on the type of weed and its moisture content.
  • Typical Uses: Often used in small-scale rural heating solutions.
• Straw:
  • GCV: ≈ 4215 kcal/kg
  • Factors Affecting GCV: Similar to wheat straw, often depends on moisture and ash content.
  • Typical Uses: Utilized in agricultural biomass boilers.
• Maize Stalk:
  • GCV: ≈ 4241 kcal/kg
  • Factors Affecting GCV: High cellulose content provides a relatively good energy output.
  • Typical Uses: Used in co-firing with other biomass types.
• Corncob:
  • GCV: ≈ 4238 kcal/kg
  • Factors Affecting GCV: Drier and denser than stalks, leading to higher energy output.
  • Typical Uses: Commonly used in biomass power generation.
• Peanut Shell:
  • GCV: ≈ 5119 kcal/kg
  • Factors Affecting GCV: High oil content in the shell contributes to a higher calorific value.
  • Typical Uses: Used in high-efficiency biomass boilers or as an energy-dense additive in biomass pellets.
• Cedar:
  • GCV: ≈ 4587 kcal/kg
  • Factors Affecting GCV: High resin content leads to a higher energy output.
  • Typical Uses: Used in high-quality wood pellet production for heating.
• Pine:
  • GCV: ≈ 4552 kcal/kg
  • Factors Affecting GCV: Similar to other softwoods but with a high resin content that increases calorific value.
  • Typical Uses: Widely used in pellet production for residential and industrial heating.
