Case Studies
Powerfeed
The Börger Powerfeed stands for high-performance substrate feeding technology and is indispensable in many biogas plants.
The Powerfeed is customized for each different type of application.
The sample applications listed here give you an impression of all the different options of the Börger Powerfeed.
Solids supply
Substrate Metering
A plant construction company specializing in optimizing biogas plants was looking for feeding technology for a 950 kW plant. It was essential that the technology would be odorless and free of gas.
The plant construction company opted for a Boerger Powerfeed. They were impressed with the Powerfeed's innovative and sophisticated technology and particularly with the high efficiency of Börger feeding technology. The renewable resources are worn down due to the positioning and type of the press unit in the Powerfeed as well as the design of blade and dosing unit. Through this they obtain a larger surface area. All the trapped air is released by compressing the solids into clumps. Less floating layers form in the tank.
By specifically dosing the solids, the agitating in the tank could be significantly reduced. The plant construction company and the plant operator are extremely satisfied with the Boerger Powerfeed.

Powerfeed duo
Powerfeed duo
The biogas plant operator was looking for reliable liquid feeding technology to feed solids into their secondary fermenter. The biogas plant was upgraded to include an additional CHP. The feeding technology was also required to load the fermenter and replace the plug screw currently used.
After finding out about state-of-the-art technology from various manufacturers, the biogas plant operator decided on Börger's Powerfeed duo. In addition to the renowned optimum reliability of Börger products, the customer was also particularly impressed by the Powerfeed duo's well-engineered, integrated design concept.
The storage tank supplied with the Powerfeed duo can be filled directly using a wheeled loader. Constant loading of the Powerfeed is guaranteed thanks to the 10 t storage capacity.
The Powerfeed and a high-capacity biogas pump form the central unit of the liquid feeding technology. The unit is very easy to operate using an operating device at the control cabinet. A control unit ensures trouble-free system operation. Different sensors constantly monitor the fill level in the Powerfeed. The data readings are transmitted to the control unit. The Powerfeed switches off automatically when the pre-set limits are exceeded.
The customer is very satisfied with the Powerfeed duo. He was won over by its optimum reliability, easy operation and efficient biomass feed.
