Benninghoven burners EVO JET

BENNINGHOVEN is a world market leader in burners for asphalt mixing plants and a manufacturer of multi-fuel burners with up to 4 fuels. The complete know-how and wealth of experience from over 70 years of burner competence support the development of unique burners with excellent properties.

Relentlessly rising energy costs and the need for careful management of limited resources require innovative technologies plus continuous improvement. The EVO JET burner has been developed by BENNINGHOVEN’s research team to meet real-world needs.

BENNINGHOVEN’s established and well-known approach to usability also played a key role in the development of this burner. The burner features a modular, highly accessible design.

The burner is mounted on a chassis to ensure it can be easily moved into place for maintenance work. A frequency converter system ensures that both the burner fan and oil pump are perfectly coordinated with one another, and can work throughout all control ranges. As a result, only the specific level of consumption requested is used for drying, whatever the output setting. Redesigned from scratch, the new silencer keeps noise to a minimum while simultaneously improving the energy conversion efficiency of combustion. This is achieved by the new air inlet layout. The improved energy conversion efficiency results from trapping the heat radiated by the front wall of the drum and re-routing the preheated air to the burner. This, in turn, means less energy is required to preheat the air, which helps to lower the costs of fuel. Burners in the EVO-JET series feature mature designs for all fuel types and have been comprehensively field-tested. This energy-saving program is rounded off by BENNINGHOVEN installing only electric motors compliant with the new IE 2 (or IE 3) standard – soon to become mandatory.

GAME CHANGER

100% green hydrogen system for road construction

With the first burner anywhere in the world that can be run up to 100% on green hydrogen, BENNINGHOVEN offers a forward-looking solution for greater sustainability in roadbuilding.
All from a single source – From the hydrogen source itself, the scope of delivery from Benninghoven covers the feed systems plus pressure regulation section, multi-fuel burner, hydrogen control section, burner control and plant components adapted to run on hydrogen.
The burner also ships with a new control system, while the carefully coordinated hardware and software solution keeps the asphalt production process cost-effective.

Burner technologies from Benninghoven can be used to equip both new plants as well as existing asphalt mixing plants. Retrofit solutions can also be deployed in plants from other manufacturers. This gives any plant operator the chance to start using the latest technologies whenever they want to – a key aspect for ensuring cost-effective, sustainable asphalt production and long-term job security.

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
