WOOD WASTE
Combustion grates
DES supplies combustion grates to a number of leading European boiler manufacturers and can therefore rely on established experience in utilising many kinds of biomass fuel. Our combustion grates are equipped with 100 % divided drying zones as well as combustion and cooling zones. This system secures an optimal control of the incineration process. All combustion zones are running independently from combustion air as well as belt speed and are installed among the most used combustion grates in Europe.
The grate bars are cast from special steel and contain a minimum 28 % of chrome and 1 % of nickel allowing a combustion temperature of more than 1.100 °C on the combustion bars.
All combustion grates are fabricated individually for the specific fuel requirements of the customer. We consider many factors for the grate design e.g. heat value, ash amount, ash melting point, chloride levels, hydrocarbon etc.
Combustion grates can be delivered with grate areas from 1 - 70 m2.

Advanced R&D for High-Performance Combustion Grate Solutions
At Danish Energy Systems we are committed to continuous research and development to deliver cutting-edge combustion grate systems tailored to specific fuels and client requirements.
Our engineering team utilizes advanced computer simulations and AI-driven modeling to optimize combustion grate design for maximum fuel flexibility, improved efficiency, and lower emissions. By simulating real-world operating conditions, we fine-tune every aspect of the combustion process—from air distribution and fuel feeding to ash handling—ensuring stable performance and compliance with the latest environmental standards.
This technology-driven approach enables us to:
Adapt grate geometry and material selection to specific fuel types (biomass, waste, RDF, etc.)
Minimize unburned residues and improve combustion stability
Reduce NOx and CO emissions through precise air staging and temperature control
Extend the lifespan of components through intelligent thermal stress analysis
Hot Gas GeneratorS
DES Direct Dryer Hot Gas Generator is a system that produces high-temperature gases for direct contact with biomass or other materials in a drying process. These systems are commonly used in industries like wood processing, agriculture, and biomass pellet production.

Preventive maintenance
Preventive maintenance of a combustion grate is essential to ensure efficient operation, reduce downtime, and extend the lifespan of the system.
Weekly Maintenance
Grate Movement Test: If the grate has moving parts, test them for smooth operation.
Inspection of Seals and Gaps: Ensure proper sealing to prevent unwanted air ingress.
Burner and Flame Inspection: Verify that the flame is burning cleanly without excessive smoke or incomplete combustion.
Temperature Monitoring: Check for hotspots or cold areas that may indicate airflow issues.
Monthly Maintenance
Detailed Grate Surface Inspection: Look for cracks, warping, or excessive thinning due to heat and mechanical stress.
Tightening of Bolts and Fasteners: Ensure all mechanical connections are secure.
Inspection of Cooling System (if applicable): Check for leaks or blockages in water-cooled grates.
Quarterly Maintenance
Deep Cleaning: Remove built-up deposits and scale from the grate and surrounding components.
Check Refractory Lining: Inspect for cracks or damage in the refractory lining around the grate.
Verify Control System Functionality: Ensure sensors, actuators, and other control elements are working correctly.
Check Exhaust and Emissions: Verify compliance with emission standards and clean filters or scrubbers.
Annual Maintenance
Full System Inspection: Conduct a thorough review of the grate system, including bearings, chains, and drive mechanisms.
Grate Element Replacement: Replace severely worn-out or damaged grate bars.
Calibration of Sensors and Controls: Ensure all temperature, pressure, and oxygen sensors are calibrated.
Structural Integrity Check: Examine welds, supports, and framework for fatigue or corrosion.
LICENSE PRODUCTION
We offer a licensing opportunity for the production of high-efficiency combustion grates, designed for industrial and commercial heating systems.
