Explosion indices in the 20 litre laboratory apparatus
with software “dust explosion plotter” for the efficient
prevention of dust explosions by preventive explosion
protection it is necessary to know the optimum
explosion indices:
‣ the dust explosibility,
‣ the lower explosibility limit (LEL),
‣ the maximum explosion pressure (P max ),
‣ the dust-specific characteristic (K max ),
‣ the limiting oxygen concentration (LOC).
Pmax value measured in the 20 litre apparatus agrees
excellent with those measured in the 1m³ vessel.
Research fully confirmed compliance with international
standards: EN 14034 and ASTME 1226 and the data
presented in the literature research.
Technology of the 20 litre apparatus leads to a
significant reduction of production costs – the purchase
cost 50%↓.
A new approach to research results in carrying out
research faster, cheaper and safer – the research cost
50%↓
Highly-effective research procedures shorten time and
lower the costs of research in compliance with high level
of safety for staff operating the machines and the
surrounding environment
– up to 2 or 3 times higher efficiency↑
