The wellknown Geldart's [25] powder classification system for gas fluidization was used by Geldart and Williams [26] to characterize the powder flowability on the basis of particle density and mean particle diameter. Under Geldart's criteria, the pulverized coal is a typical group C powder, characterized by poor flowability and strong cohesive forces.

Recently, Dunn et al. [22], [23], [24] have conducted experiments on a coaldriven RDE and found that the addition of the coal powder could broaden the operational regimes of the engine. To elaborate the detonation of the coal powder, Dunn et al. [25] established a theoretical model to describe the detonation combustion of the coal powder.

Coal is a black or brownishblack sedimentary rock that can be burned for fuel and used to generate electricity. It is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion (burning). Coal is the largest source of energy for generating electricity in the world, and the most abundant fossil fuel ...

Blind coal: Blind coal is in powder or little bulk shape, in black color with shining metallic luster. The coal has low impurity, high content of fixed carbon (over 80%); the coal has low volatile component of lower than 10% and high ignite point. When burned, coal soil should be added to reduce thermal power.

This results in an increased moisture adsorption capacity of the coal powder. On the other hand, an increase in ambient temperature means that water molecules adsorbed on the surface of coal powder particles can gain higher kinetic energy to break free from the surface. As a result, the amount of water vapor adsorbed by coal powders decreased ...

Activated charcoal is a fine, odorless, black powder. It is produced by heating charcoal to an extremely high temperature in an environment without oxygen, such as a tank. Once activated, the powder's pores trap chemicals, making it effective at treating overdoses and chemical poisonings by preventing the body from absorbing the toxic substances.

In 1840, a new method of drilling technology emerged: rotary drilling. This system relied on a man turning, by hand, a drill steel that would slowly work a hole into the rock. This system was originally only used in coal and very weak materials, as the pressure and speed of rotation were not fast enough for good penetration in hard rock.
