Self-ignition in the Grewer Oven
In the investigation of self-ignition in the Grewer Oven for the pure test item, an endothermic effect was detected in the temperature range of 50 – 110 °C, which may be caused by the drying of the test item. No further thermal effects could be observed up to maximum test temperature of 425 °C. After the measurement a black residue remained in the basket.
For the test item in mixture with Kieselguhr an endothermic effect was detected, in the temperature range of 40 – 70 °C, which may also be caused by the drying of the test item. No further thermal effects could be observed up to maximum test temperature of 425 °C.
Table 1 summarizes the results of the Grewer Oven experiment.
