✦ Synopsis

by previous workers 2-4, around 50 kcal. mole-1 for fuel-rich and 20 kcal. mole-1 for oxygen-rich mixtures, and that the trend with mixture strength is n~versed.

That the present temperature coefficients are of general applicability was shown by studies in the presence of homogeneous and hetero~,neous additives. For instance the addition of five per cent propane or 0.5 per cer~* fz.rmaldehyde l~educed the temperature required to initiate detonation and approximately halved the delay observed in their absence, but the additions did not influence the temperature coefficient. Similarly, additions of coal dust slightly reduced the detonation temperature and the delay but did not influence the temperature coefficient.

Dust explosion hazard exists in plants and facilities wherever combustible dusts are handled. The minimum ignition temperature of dust clouds is an important factor requiring special attention for the design of any explosion preventive measures. The present paper is confined to a study of the minimu
