    Maatregelen ter vermindering van fijnstofemissie uit de pluimveehouderij: labproef karakterisering van olievernevelaars (druppelgrootte en snelheid) = Measures to reduce fine dust emission from poultry houses : laboratory study: characterizing oil spraying nozzles (droplet size and velocity)

    Get PDF
    Two spraying nozzles have been studied with respect to droplet size and velocity of the sprayed rapeseed oil depending on the applied liquid and air pressures. For the nozzle with a wide angle round spray the air pressure should be lower than the oil pressure and should be in the range of 1.5 and 2.5 bar. For the flat spray nozzle the variation in droplet size is small and the oil and air pressure may vary between 2.0 and 3.0 ba

    Maatregelen ter vermindering van fijnstofemissie uit de pluimveehouderij: ontwikkeling van een oliefilmsysteem voor leghennen in volièrehuisvesting = Measures to reduce fine dust emission from poultry houses: development of an oil spraying system for layers in aviary housing

    In phase one of this study an oil spraying system was developed for layers in aviary housing. In phase two the effect of the system on emissions of fine dust was determined. Emissions of PM10 and PM2,5 from the Big Dutchman aviary system were reduced by 18 and 65% respectively. No reductions were found for the Meller aviary. No effect was found on personal dust exposure or egg production. In the oil film rooms higher mortality was found. Further research is needed to clarify this

    Stofreductie in kuikenstal dankzij oliefilm

    Stof in de stal is al jarenlang een aandachtspunt uit oogpunt van arbo en diergezondheid. De laatste jaren is daar de emissie van fijnstof naar de buitenlucht bijgekomen, aangezien de EU normen heeft gesteld voor maximale concentraties fijnstof in de buitenlucht. Er zijn normen gesteld voor deeltjes kleiner dan 10 micrometer (PM10) en voor deeltjes kleiner dan 2,5 micrometer (PM2.5). De veehouderij draagt naast verkeer en industrie bij aan de emissie van fijnstof. Het merendeel van het fijnstof uit de veehouderij komt uit pluimvee- en varkensstalle

    Maatregelen ter vermindering van fijnstofemissie uit de pluimveehouderij: optimalisatie van een oliefilmsysteem bij vleeskuikens = Measures to reduce fine dust emission from poultry: optimization of an oil spraying system for broilers

    The effects of oil dose, spraying frequency and of technical optimizations of an oil spraying system on the reduction of fine dust were studied. Daily application of 8 to 15 ml of oil per m2 of bedding up from day 21 of the production cycle resulted in a 60% and 80% reduction of PM10 and PM2.5 emission, based on particle mass. Technical optimizations substantially reduced oil droplet

    The performance of two experimental air scrubber was investigated during 9 months on two broiler houses. The inlet ventilation air of the houses is led through a subsoil heat exchanger. In this report the removal efficiencies of the scrubber are reported for ammonia, odour and fine dust (PM10 and PM2.5)
