Experimental studies for determ<strong>in</strong><strong>in</strong>g self-heat<strong>in</strong>g<br />
Large-<strong>scale</strong> silo tests<br />
• A smoulder<strong>in</strong>g fire can go on for a long time before it is detected<br />
• Early detection requires reliable measurement of<br />
low concentrations<br />
• The spread of the pyrolysis core is slow and downwards<br />
• The upward transport of pyrolysis gases is slow<br />
• Good repeatability of the experiments. Suitable as validation<br />
data for mathematical simulation.<br />
