TRASH RACKS
COANDA-RISTER/FOSSEKALLEN-INNTAK
The intake at a power plant is complex and must be carefully designed before construction begins.
There are many considerations to take into account, not least the conditions in the watercourse where the plant is to be built.
If the intake or grate is incorrectly designed, this will lead to lost production and reduced income. Enerquip has extensive experience in manufacturing grinders for all types of intakes. We also supply grates with the Coanda effect, often referred to as Fossekallen intakes.
TRASH RACKS/ FINE GRATER
In front of the intake cone, you must install a grate/screen that prevents larger objects such as branches, twigs, and stones from entering the waterway, thereby avoiding damage to the pipeline and turbine.
The gate also prevents fish and animals from entering the waterway. To avoid ice problems, the grate must be placed at a sufficient depth from the water level in the intake basin.
The grate is designed and positioned to minimize head loss and provide favorable inlet conditions.
The opening between the bars in the grate must be adapted to the plant and the conditions in the individual watercourse, taking into account production, operating time and organisms in the intake basin.
The grates are usually manufactured in stainless steel, but can also be supplied in untreated or hot-dip galvanized steel, PE and composite material.
