Turnkey Engineering, Procurement and Construction Contract for Biomass Processing Unit (wood pellets) for a coal fired Power Plant.
When handling bulk solids, the creation of dust is an undesirable, yet often seemingly unavoidable result. Taking woody biomass such as wood pellets or chips as an example, dust emission leads to production losses, negatively affects the environment and involves a major safety risk in the form of a potential dust explosion.
Geldof has acquired extensive knowledge in providing effective biomass handling solutions for logistic and utility companies throughout Europe.
It is clear that dust control measures are required for the safe and environmentally appropriate handling processes in all related equipment. This year Geldof realized a turnkey wood pellet handling installation for the Electrabel Gelderland Power plant in the Netherlands. Barges are unloaded pneumatically at this site at the rate of 500 tons per hour via a mobile unit that eliminates dust emissions. The complete circuit—from quay to boiler—uses completely closed conveyer belts, silos, hammer mill and buildings kept at a small under pressure to avoided any possibility for wood dust to escape. It is obviously unavoidable, however, that wood dust is present within the system, Therefore secondary containment measures such as dedusting and fire and explosion protection equipment are in place. All of our realizations are accompanied by all required studies, documents and certification.
Main mechanical project items include: barge discharging 500 T/H via mobile pneumatic unloader, quai belt conveyors 500T/H, silo feeding with pipe belt conveyors 500T/H, 2 carbon steel silos 5000 m³ silos with screw reclaimers, chain conveyors 120 T/H, pellet dosing bins, complete processing building including hammer mills and wood dust screens, wood dust silos, pneumatic transport/boiler injection.
Scope: EPC - design, engineering, fabrication, mounting, testing, commissioning, of all followings works: civil (including foundation), mechanical (including steel construction), E&I, ferro-non ferro separation, fire and explosion protection and detection, dedusting, HVAC…
