Multi-fuel burners
Independent, flexible, cost-efficient
Up to three fuels can be added to a burner, which dries and heats the base material and is designed as a single-fuel burner in its standard version. This turns the burner into a combination burner, which means that different variants of oil, natural gas, liquid gas and all gaseous substances (DME, etc.) available on the market, coal dust, BtL and wood dust can be combined as fuels.
> No plant downtime caused by lack of raw materials or delivery issues
> If the price of a fuel fluctuates, the cheapest fuel at the time can be selected.
> Flexible use of alternative fuels that allow for carbon-neutral drying
Tested quality
In-house testing procedures
> Function and safety checks
> Burner pre-configured before delivery
> Service and customer training courses (complete equipment on site)
> Testing of new developments (R&D)
The BENNINGHOVEN burner guarantee: 100 % final test
> Each burner that leaves the factory has run on the test rig, has undergone thorough testing and is preconfigured for the customer’s fuel(s).
> Mechanical, electrical and process testing
On the ball – and one step ahead
BENNINGHOVEN has a defined development process for burners. We engage in a continuous exchange with the customer regarding the ongoing progress.
Our customers also benefit from our close cooperation with institutes and authorities, which is reflected in our professional support for approval processes and smooth process implementation.
Use of state-of-the-art development tools
> CFD simulation – numerical simulation of the flow dynamics to derive recommended actions for optimising components and systems
> DEM simulation – particle simulation for plant and process optimisation
> System simulation to visualise and optimise complex interactions
Easy operation – strong performance
Intelligent control system
> High ease of operation
> Option for remote service for direct access to the burner control and diagnostics of individual signal inputs/outputs
> Monitoring of all control elements
> Frequency-controlled fan motor
> Air volume control using the fan speed control
> Monitoring of the firing program in accordance with the
> combined fuel – air control
> Output control with temperature sensor on the dryer drum discharge
> Advance availability check for parts and spares
> Prepared for mixed firing
> Implementation of additional fuel curves (characteristic curves)
> Smooth changes between curves (burner does not have to be shut down for changing the fuel)
> If gas is used as a fuel, expensive peaks can be avoided because the controller automatically switches to another fuel
