Correct boiler design based on fuel characteristics, ash behavior, and feed characteristics.
Biomass fuels differ significantly in terms of physical structure, moisture content, ash characteristics, and chemical composition. Therefore, each biomass fuel requires a specific combustion and boiler design.
Typical characteristics: Lower heating value: 3,500–4,800 kcal/kg Ash content: 0.3% – 2% Combustion behavior: Stable and easy to control
Typical characteristics: Lower heating value: 2,800–4,200 kcal/kg Ash content: 5% – 15% Note: High alkali metal content → ash melting behavior is critical
Typical characteristics: Lower heating value: 3,000–5,200 kcal/kg Ash content: 1.5% – 6% Combustion: High energy density, aggressive ash behavior
Typical characteristics: Fuel characteristics vary depending on the industrial process. Flexible boiler design is required.
Typical characteristics: Lower heating value: 1,800–3,500 kcal/kg Moisture control is critical Fuel feeding and pre-drying are important
Typical characteristics: Emission and combustion control require advanced engineering.
Note: This group requires project-specific boiler design rather than standard boilers.
