Solutions for the wood-based panel industry
With energy systems for more efficient and sustainable wood-based material production
Make your production process more efficient and sustainable by optimally aligning your energy generation with your energy consumption. To ensure that your energy systems ideally use residual and biomass-based fuels generated in the production process, we support you in integrating individual solutions into an existing process and designing new systems tailored to your production process.
Energy systems and products for your wood-based panel plant
Grate furnace
We recommend a combustion system with a reciprocating grate firing system to enable you to use a wide range of coarse fuels for your energy supply. By injecting dust and granulate fractions from your production process into the combustion chamber, you can also use fossil fuels to generate energy. Energy can be extracted via thermal oil, hot water, flue gas or steam and can be controlled separately if required.
+ Energy generation optimally tailored to the consumer
+ Robust construction and low maintenance requirements
+ Fully automated operating control
+ Short response times to load changes
Fuel-feeding hopper
Our fuel chute is equipped with level sensors and integrated distribution flaps on several levels to ensure that the biomass-based fuel is ideally distributed on your reciprocating grate. The individually controlled pushers enable even distribution across the entire width of the grate. Thanks to the double-walled, water-cooled design and integrated extinguishing nozzles, overheating and backfires are effectively counteracted. In addition to the water-cooled version, we offer an air-cooled design upon request.
+ Uniform fuel feed across the entire width of the grate
+ Reliable burn-back prevention
+ Pressure-shock-resistant design with explosion relief possible
+ Wear plates under the slides to protect the fuel shaft
Reciprocating grate
The air-cooled reciprocating grate offers you the option of burning a wide range of coarse fuels. Wood-based production residues, bark and other biomass as well as recycled wood waste can be used. Up to 100 MW firing capacity can be achieved on up to three grate tracks, each with three to five zones. For peak combustion, both the feed and the combustion air supply can be controlled individually for each zone. We offer different grate bars for coarse and moist biomass as well as waste wood.
+ Grate sizes from 16 to 120 m²
+ Stable grate structure
+ Optimized combustion through individualized zone control
+ Almost complete burnout of the fuel
+ Ideal for moist wood chips and bark (up to 60% water content)
+ Easy maintenance thanks to individually replaceable grate bars and well-designed access points
Dust burner
The dust burner can be used to burn sanding or sieve dust in a grate-fired combustion chamber. Wood dust and combustion air are blown into the combustion chamber via the sleeve in separate sections. The flame can be modulated by varying the internal and external combustion air flows depending on the load.
+ No fossil fuel required
+ Optimal combustion by adjusting the combustion air supply
+ Safe self-ignition due to combustion chamber temperature
+ Short reaction time to load fluctuations
Hot gas cyclone
The fly ash concentration in flue gases can be significantly reduced by installing a hot gas cyclone. Flue gases with temperatures above 1000°C can be cleaned thanks to the refractory lining and temperature-resistant immersion tubes. The geometry of the cyclone and immersion tube is CFD simulated and optimized for separation rate and pressure loss. The modular segment design simplifies transportation and assembly.
+ Low wear in ducts and cyclones
+ Good accessibility for easy inspection and maintenance
+ Improved plate quality for directly heated dryers
+ Special sizes on request
Thermal oil recovery heat system
Waste heat recovery systems enable thermal oil to be heated directly from hot flue gases. The recirculation of cooled flue gases optimizes both the combustion process and the overall efficiency. Automated cleaning of the heating surfaces guarantees high efficiency with minimum maintenance. Process or emergency cooling guarantees safe and automated operation of the system and prevents premature aging of the thermal oil. Additional equipment with nitrogen blanketing, a fine filter station or continuous light-ends separation allows you to further extend the service life of the thermal oil and system availability.
+ Individual design of radiant and convective heaters
+ Prevention of premature thermal oil aging
+ Automated cleaning of the heating surfaces
+ Robust system despite rapid load changes
Pump station
Pump stations for primary and secondary circuits guarantee consumers a reliable and efficient thermal oil supply. The stations, including fittings, sensors and drive, are delivered fully preassembled and tested on steel frames. For a longer service life and high efficiency, the stations can be frequency-controlled or designed for low-speed operation, depending on the area of application.
+ Ideal accessibility
+ Easy transportation and installation
+ Continuous vibration and leakage monitoring
