Innovative transport solutions for power plants

Each of the so-called hopper cars removes a total of 1,600 m³ / h of material. In addition to the dust return, the hopper cars are equipped with dry extinguishing lines including spraying in the feed bunker and filters. In the event of a fire, the water is fed in by the local fire brigade with the dry fire line on the hopper car. In addition, a fire hose can be connected to a separate riser if necessary to extinguish fires on the hopper car. For cleaning, there are suction and wet cleaning lines on the hopper car, to which the operator can connect the corresponding equipment.

The hopper cars are coupled with the harbor cranes. This means that they can be moved individually and to any ship unloading position on the pier. During the unloading pauses, the clamshell bucket and multi-section grab can be safely placed on the hopper car.



In the Port of Copenhagen, 3,200 m³/h of biomass are handled daily at the Amagerværket power plant. The amount of dust that arises during loading increases the risk of ignition. With more than 60 years of experience in individually conceptualized bulk materials transport and as a competent partner in the field of fire-endangered and explosive bulk goods, Loibl developed an innovative, ATEX-compliant conveying concept that more than lived up to the expectations of the largest Danish energy supplier.
