Energy Efficiency Optimization Strategies for Briquette Production
-
Machine Selection & Design
Choose the Right Press Type: Hydraulic Presses are best for high-density briquettes (1.2–1.4 g/cm³) at 60–80 kWh/ton. Screw Presses are more efficient for low-density biomass (~0.8 g/cm³) at 40–60 kWh/ton.
Variable Frequency Drive (VFD) Motors: Adjust motor speed based on load, saving 15–25% energy.
-
Raw Material Preparation
Moisture Control: Dry biomass to 8–12% moisture (reduces energy use by 20–30%).
Particle Size Optimization: Crush feedstock to <5 mm for uniform compression, lowering energy waste.
-
Process Optimization
Pre-Heating (for Biomass): Heat to 80–100°C to soften lignin (natural binder), reducing compression force.
Optimal Compression Force: Balance pressure (e.g., 100–150 MPa) to avoid overworking the motor.
-
Maintenance & Upgrades
Die & Roller Lubrication: Reduces friction, cutting energy use by 5–10%.
Worn Parts Replacement: Replace dies/liners when wear exceeds 0.3 mm to maintain efficiency.
-
Energy Recovery Systems
Waste Heat Utilization: Capture heat from motors/dryers for pre-heating feedstock.
Regenerative Braking (Hydraulic Presses): Recovers energy during decompression cycles.
