VEGAPULS 68 Application - Biomass Level Measurement

VEGAPULS 68 Non-Contact Radar Transmitter

Application

Power station in Belgium with a plant where the boiler is powered with wood pellets alongside the coal fired stations. CO2-neutral fuel arrives by ship and is transported by conveyor belts to the warehouse. The pellets must be stored as dry as possible to retain maximum calorific value and avoid self-ignition by biodegradation.

Transporting the wood pellets produces excessive dust and filling noise which can reduce visibility in the area. A continuous and reliable filling level measurement is essential for the constant supply of biomass fuel.

Compared with coal, wood pellets are lighter, have a lower calorific value and they degrade more quickly, so they need to be used in their optimum condition. Thus a continuous turnover of product by perfectly controlled supply logistics, storage and handling are especially important. A reliable filling level measurement technology is a key part to this.

VEGA Level Sensor - VEGAPULS 68 Radar Level Sensor

Solution

Two dust ATEX approved VEGAPULS 68 radar sensors are mounted on the conveyor car. VEGAPULS 68 level sensor reliably measures the filling height in the warehouse without contact and control the moving conveyor position. Heavy dust and deposits, abrasion and filling noise have no influence on the level measurement.

The reliability of this measurement enables the conveyor to fill the warehouse fully automatically without the need for supervision by an operator. The VEGAPULS 68 has two radar signals which have no influence on each other.

VEGAPULS 68 radar level sensor also supply the necessary information about the free storage capacities to the unloading rig at the pier as well as the available stocks for optimisation of the fuel supply to the power station control centre. This ensures there is always a supply of wood pellets to the power station.
