Fuel feeder systems
Steady and continuous feeding is the key to stable operation, maximum efficiency, and lower operational and maintenance costs.
No pre-treatment saves millions for our customers
In our waste-to-energy plants, there is no need to pre-treat the waste. Besides saving time, eliminating pre-treating lowers both your operation and maintenance costs, saving approximately 15 €, or $20, per metric ton of waste. This means that a small-medium sized plant can save more than 1 million Euro each year and larger plants even more.
Proper feeding of waste onto the grate needs to be continuous and adapted to the grate’s transport capacity. Our technology ensures an even fuel layer across the grate so that steady energy output and maximum efficiency are ensured.
Steady energy production
In short, “feeding” means dosing the right quantity of fuel to the grate for steady combustion and energy production. However, it’s also important to minimize wear and tear of the feeding system so that your long-term maintenance costs are kept to a minimum.
Hydraulic mechanism on feeder
Continuous waste transport with no clogging
We design our feed hoppers to provide continuous waste transport to the water-cooled chute with no clogging, which means your plant operates with fewer shutdowns.
Hydraulic dampers keep the facility safe during start up and close down
During start up and close down of a plant, two powerful, hydraulically operated dampers are at work. Positioned between chute and hopper, they close automatically in the event of a power failure and can be closed manually in the event of fire in the chute.
However, the chute is fire-resistant because of its cooling system. The water-cooled feed chute is made of strong, steel plates, and the smooth sides have a negative inclination to ensure free waste transport through the chute to the feed platform.
Waste bunker and feed hopper
Changeable wear plates = lower maintenance costs
The grate is fed at a variable rate adapted to the energy production by means of a hydraulically operated pusher. Changeable wear plates cover the front and top of the feed pusher. The sides of the water-cooled feed chute are covered by changeable cast-iron plates that reach the top of the feed pusher, giving you a lower maintenance cost.
Feed flexibility ensures optimal efficiency and minimum wear and tear
The continuous, slow movement of the feed pusher can change according to energy production and the combustion control, which provides a steady, continuous waste feed onto the grate. This ensures maximum efficiency and minimum wear and tear.
