Why biomass needs better automation
Gas has constant properties. Biomass moisture can swing 20–45% in a single batch. Each change requires simultaneous adjustment of fuel feed, primary air, secondary air and exhaust — in real time.
What the 6 VFDs control
Fuel feed screw, primary air fan, secondary air fan, exhaust fan, ash removal system, and auxiliary drives. Each runs at variable speed for precise process control.
Cascade PID regulation explained
Master PID holds output temperature at setpoint. When fuel quality changes, it adjusts fuel feed target. Slave PID smoothly accelerates the screw while coordinating air supply. All automatic, no operator intervention.
O₂ monitoring for combustion quality
An analog oxygen sensor in flue gas provides direct feedback on combustion quality. Target: 6–9% O₂. The automation fine-tunes air-fuel ratio continuously for maximum efficiency.
What operators actually experience
Temperature stability ±3–5°C vs ±15–25°C without automation. 10–20% fuel savings from optimal air-fuel ratio. The operator monitors — the system runs itself.
