Selecting the right industrial boiler fuel is a critical decision that directly impacts operational costs, energy efficiency, and environmental compliance. For international businesses seeking a reliable, high-performance, and cost-effective biomass fuel source, Vietnam offers some of the best fuelwood solutions.
This article will break down the essential factors—moisture content and calorific value (heating value)—to help you understand why Vietnamese wood chips and sawdust briquettes are the superior choice for your steam boiler or hot water boiler.
🌲 Top Fuelwood Types from Vietnam for Industrial Boilers
Vietnam, with its abundant agricultural and forestry resources, provides excellent sources of biomass fuel. The most commonly exported and highly efficient types include:
| Fuelwood Type | Key Advantages for Industrial Use | |
| Acacia Wood Chips/Logs | High density, excellent calorific value, sustainable supply. | |
| Rubberwood (Hevea) | Moderate density, widely available, consistent quality. | |
| Sawdust Briquettes / Wood Pellets | Uniform size, very low moisture, high energy density, ease of handling. |
💧 The Crucial Factor: Fuelwood Moisture Content
The moisture content (MC) of fuelwood is the single most important factor determining its efficiency.
Understanding Moisture Content (MC)
Moisture content is the percentage of water present in the wood. It significantly affects the net energy released during combustion.
Why Lower MC is Better for Boiler Fuel
Wasted Energy: When wood is burned, the energy produced must first be used to evaporate the water content. The higher the MC, the more heat is wasted as steam, leading to lower boiler efficiency.
Reduced Net Calorific Value (NCV): Water significantly lowers the effective energy you get from the fuel.
Lower Emissions: Drier wood burns cleaner and more completely, reducing smoke and particulate matter.
✅ Vietnamese Advantage: Vietnamese suppliers are experts in air-drying and kiln-drying wood. Our premium wood chips and biomass briquettes are typically processed to an optimal low moisture content (often < 15% for briquettes and 20-35% for kiln-dried chips/logs), ensuring maximum heat output upon arrival.

🔥 The Power Source: Fuelwood Calorific Value (Heating Value)
Calorific Value is the amount of heat energy released when a quantity of fuel is completely burned. It is typically measured in kJ/kg (kilojoules per kilogram) or BTU/lb (British Thermal Units per pound).
Gross vs. Net Calorific Value
Gross Calorific Value (GCV) / Higher Heating Value (HHV): The maximum heat released when the fuel is burned, and the combustion products (including water vapor) are cooled back to the starting temperature.
Net Calorific Value (NCV) / Lower Heating Value (LHV): The heat released minus the energy lost due to the latent heat of vaporization of the water in the fuel. NCV is the real, usable energy for your boiler.
For industrial users, always compare fuel based on the Net Calorific Value (NCV).
Typical NCV for Vietnamese Fuelwood
| Fuelwood Type | Optimal Moisture Content (MC) | Approximate NCV (Air-Dry Basis) | |
| Sawdust Briquettes/Pellets | < 15% | 4,000 – 4,500 kcal/kg | |
| Kiln-Dried Acacia/Rubber Logs | 20-30% | 3,200 – 3,800 kcal/kg |

📈 Why Import Vietnamese Fuelwood in Bulk? A Commercial Perspective
Choosing a Vietnamese partner for your bulk fuelwood import offers unparalleled commercial advantages:
