Solid fuel

Linka Energy’s walking floor system is an automated solution for the continuous and controlled feeding of solid biomass – such as straw, wood chips or organic waste – to the next process stage in the biogas plant. The system ensures stable and uniform feeding, optimising plant operation and efficiency. The automated process reduces the need for manual handling, improving the working environment and minimising the risk of work-related injuries.

The walking floor system from Linka Energy ensures uniform biomass feeding with high capacity and minimal manual intervention. This contributes to an improved working environment by reducing physical strain and the risk of workplace accidents. The system’s reliability and efficiency make it an ideal solution for biogas plants seeking to optimise their biomass handling.

The system consists of horizontal scraper arms that move the biomass towards a submerged auger, which then conveys the material onwards to the combustion unit or further processing.

This configuration ensures uniform fuel feeding, high capacity and minimal manual handling, resulting in stable operation and a reduced risk of operational disruptions.

Walking floor systems are often integrated with other components such as screw conveyors and reception hoppers to optimise the entire fuel feeding process.

The automated solution also contributes to a healthier working environment, with fewer physically demanding tasks and a lower risk of work-related injuries.

Linka Energy has implemented walking floor systems in several projects.

For example, in the Vinkel Bioenergy project, the wood chip boiler plant is equipped with a walking floor (scraper system), stoker augers and Linka’s patented combustion technology.

This solution ensures not only high operational efficiency, but also a workplace with reduced physical strain and greater operating comfort for operators.

This provides efficient and automated fuel handling, which is critical to plant performance and operational reliability.

The first station in biomass handling – a robust and spacious unit for the reception and temporary storage of solid biomass such as straw, wood chips or organic residual material.

The reception hopper ensures uniform material flow and acts as a buffer between unloading and the subsequent process stages.

The solution is modular in design and flexible in capacity, making it suitable for different biomass types and for both small and large plants.

Linka Energy offers reception hoppers designed for efficient handling of various types of solid biomass, including straw, wood chips and organic residual material.

The reception hoppers are often integrated with conveying or feeding systems such as screw conveyors or walking floors, enabling continuous and controlled feeding of the biomass.

This configuration reduces the need for manual handling and minimises the risk of operational disruptions.

The system can be adapted to different types of solid biomass and scaled according to capacity requirements, making it ideal for both smaller and larger biogas plants.

An example of the application of Linka Energy’s reception hoppers is found in their straw handling system, where straw bales are received, pre-treated and conveyed to the next process stage in the biogas plant.

This system is designed to handle up to four straw bales per hour and ensures an efficient and automated process from reception to biogas production.
