Fire in a spray drying installation is one of the possible hazards in producing powders. Such a fire is often related to lumps of powder which start to smoulder and subsequently self-ignite or break open and ignite the rest of the powder in the spray dryer. With regard to risk assessment and fire prevention, it is important to determine whether the powder of interest exhibits selfignition at the temperatures occurring in the drying installation and if the amount of CO produced prior to self-ignition exceeds the detection limits of the CO detection system.
To have better view on the safety of spray drying processes and a better understanding of the impact of changes in the production process NIZO can perform smouldering trials. To be able to do a proper risk assessment NIZO offers a standard package of three analyses per sample.
