Even pouring or spraying acetone over red-glowing coal will not ignite it, due to the high vapour concentration and the cooling effect of evaporation. [79] Acetone should be stored away from strong oxidizers, such as concentrated nitric and sulfuric acid mixtures. [81] It may also explode when mixed with chloroform in the presence of a base.
For use in thermal power plants, coal is ground into dust using a device called a powdered coal mill. [1] The resulting product, called powdered coal or pulverized coal, is then generally used in a fossil fuel power plant for electricity generation. Pulverized coal is a significant dust explosion hazard, as large quantities are suspended in air ...
Smokeless coal is more efficient than a conventional open coal fire indoors because the high working temperature is released into the room as infrared radiation, as can be judged by the bright red color of a mature fire. The hot gases produced are lost up the chimney, thereby reducing efficiency just as in an open coal fire.

In this respect, gasification has a significant advantage over conventional combustion of mined coal, in which CO 2 resulting from combustion is considerably diluted by nitrogen and residual oxygen in the near-ambient pressure combustion exhaust, making it relatively difficult, energy-intensive, and expensive to capture the CO 2 (this is known ...
A spray is a dynamic collection of drops dispersed in a gas. [1] The process of forming a spray is known as atomization. A spray nozzle is the device used to generate a spray. The two main uses of sprays are to distribute material over a cross-section and to generate liquid surface area.
A Lake Norman woman who developed kidney cancer sued Duke Energy on Wednesday over its disposal of toxic coal ash near and beneath lake-area homes and businesses in the 1990s and 2000s.
The aftermath of the widespread wildfires – which scorched over 37,000 acres and damaged or destroyed more than 16,000 structures – has prompted questions about the long-term health impacts of ...
