TL;DR: In this article, the explosion characteristics of micron-and nano-size magnesium powders were determined using CSIR-CBRI 20-L Sphere, Hartmann apparatus and Godbert-Greenwald furnace to study influence of particle size reduction to nano-range on these.

TL;DR: In this paper, the authors report the results of an experimental study on explosion pressure measurement in closed vessel deflagration for methane-air mixtures over its entire flammable range at standard pressure and temperature in vessels with variable geometry and size.

TL;DR: In this paper, the authors present results of detailed experimental work on determination of Limiting Oxygen Concentration (LOC) and influence of reduced oxygen levels on explosion severity data for two types of coals with varying volatile matter as 27.18% and 19.69% from Jharia coalfield of India determined at ambient conditions with 20 L spherical vessel established at CSIR-CBRI.

TL;DR: In this paper, the minimum ignition temperature of a cloud of polyethylene, an organic dust, was determined using the Godbert-Greenwald furnace apparatus for different particle sizes and dust concentrations.

TL;DR: In this article, a model was developed for determining the minimum ignition temperature for an organic dust cloud, polyethylene, simulating the conditions in the Godbert-Greenwald furnace, based on two-stage oxidation mechanism involving devolatilization/decomposition of the solid particle and homogeneous oxidation of volatile combustible products.
