The role of the biomass grate furnace feeding system

The feeding system of a biomass grate furnace handles steady fuel delivery and combustion organisation, and its role centres on continuous feed, stable combustion, equipment protection and economic performance.

Continuous fuel delivery and distribution

Fuel passes through a hopper, belt conveyor and screw feeder from storage to the silo or burner at the furnace front, keeping supply uninterrupted. The screw feeder pushes fuel with rotating flights for sealed delivery and precise dosing, reducing leakage and waste. A vibrating feeder and distributing air work with the screw conveyor to spread fuel evenly across the furnace, avoiding local piles or empty burning and improving combustion uniformity.

Effect on combustion stability

The feeding system prepares and matches the fuel to its characteristics and works with combustion parameter control, so that particle size and moisture entering the furnace are close to the combustion requirement and stable ignition and continuous burning are possible.

Equipment protection and safety

The feed path includes anti-blocking and anti-flashback measures, so a blocked channel does not interrupt fuel supply and furnace flame cannot travel back along the feed path, protecting equipment and operators.

Economic and environmental gains

Precise dosing and combustion control raise energy utilisation to 94% or more, cut fuel waste and lower fuel cost. Pre-combustion preparation and even air distribution also reduce the dust and harmful gas emitted by incomplete combustion.
