Ever wondered how waste turns into energy at Rabbit Waste Management? Here’s a little peek behind the scenes… 🔥
The Fuel Feed System ⚙️
At the heart of our waste-to-energy process are four large screw augers. These heavy-duty screws are each powered by an individual motor and gearbox, and controlled by variable speed drives, meaning we can adjust the speed depending on how much fuel our combustion system needs at any given moment.
Capacity? 📊
1 set of 4 screw augers can move around 115 tonnes in 24 hours ⏳
Once moved by the augers, the fuel is transferred onto a series of precision conveyor systems:
✅ A cross conveyor ↔️ takes fuel from the augers and shifts it sideways
✅ An inclined conveyor ⬆️ then lifts it to the top level
✅ Finally, the fuel is dropped into metering bins, which feed it into the combustion chamber 🔥
Both conveyors use chevron belts, specially designed to stop material slipping on steep surfaces, and are built with rollers to reduce friction and support heavy loads.
At either end, belt scrapers remove residual waste, improving efficiency, extending belt life, and reducing the need for manual cleaning.
Like the augers, the conveyors also run on variable speed drives. That gives us full control to increase or decrease flow as needed, maximising safety, efficiency, and power generation⚡
