🌱 Wood Pellets – The Factor That Determines Factory Operational Efficiency
The color, texture, and durability of wood pellets not only reflect product quality but also determine how effectively they are used in industrial boilers. Understanding how to distinguish wood pellets by color helps businesses avoid buying low‑quality goods that can cause serious damage to production activities.
🎯 Classification of Wood Pellets by Color
1️⃣ Pellets from Sawdust and Wood Chips
Characteristics:
Color: Bright shiny yellow, uniform.
Texture: Low dust, smooth surface, firm.
Quality: This is a high‑quality pellet type, produced from clean raw materials such as natural sawdust and wood chips.
Price: Higher than other types due to superior quality.
2️⃣ Pellets from Rubber Wood Chips and Cashew Wood
Characteristics:
Color: Grayish black, shiny surface but not as bright as pellets from sawdust.
Texture: When knocked together, they produce a distinctive “clacking” sound.
Quality: Average quality, commonly used in applications with less stringent requirements.
3️⃣ Low‑Quality Pellets
Characteristics:
Color: Dull black (mixed with soil, sand), or unusually green, red, yellow (mixed with trash, impurities).
Texture: Easily crumbles, rough surface, contains a lot of dust and impurities.
Quality: Very low, harmful to equipment and reduces combustion efficiency.
🔥 Method for Testing Wood Pellets with Water
A simple method to check the quality of wood pellets is to put them in a glass of water:
Step 1: Put a pellet into a glass of clean water.
Step 2: Observe when the pellet begins to expand.
High-quality pellet: When expanding, you will see a uniform texture, without impurities.
Low-quality pellet: When expanding, soil, sand, bark or other impurities will appear.
Note: This method helps visually inspect the internal components of the pellet, but it needs to be carried out carefully to ensure accurate results.
💡 Other Criteria for Evaluating Wood Pellet Quality
In addition to color, businesses should also check the following criteria:
1️⃣ Moisture Content
High quality: Moisture content below 10%, ensuring good combustion and no furnace blockage.
Low quality: High moisture content (above 15%), making the burning process inefficient.
2️⃣ Ash Content
High quality: Low ash content (below 2%), leaving little residue after burning.
Low quality: High ash content (above 5%), causing ash to accumulate in the furnace.
3️⃣ Calorific Value
High quality: Calorific value ranging from 4,000 – 4,500 Kcal/kg, ensuring stable combustion efficiency.
Low quality: Low calorific value (below 3,500 Kcal/kg), increasing fuel consumption.
