What is coal used for? - USGS

Coal is primarily used as fuel to generate electric power in the United States. In coal-fired power plants, bituminous coal, subbituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into high-pressure steam, which drives a turbine, which produces electricity. In 2019, about 23 percent of all electricity in the United

Coal – Global Energy Review 2020 – Analysis - IEA

We expect global coal demand to fall by about 8% in 2020, the largest drop since World War II, with coal use declining in virtually every sector of every region in the world. In China, coal demand will decline in 2020 by around 5%, despite the gradual recovery since February lockdown. Coal-fired power generation will be hit especially hard, because the power system is crowded by low variable ...

NEC Article 502: Class II Hazardous Locations ECM

It’s much easier to keep out dust than gases, so Art. 502 is much shorter than Art. 501. Often, the only requirement is that the equipment be identified for the location. This is a plugged chute detector on a coal chute. Notice the coal dust near the base of the unit. The normal presence of ignitable dust makes this a Class II, Div. 1 location.

The hole in the coal is filled with the mud using the wooden tamping tool to push the mud in to the hole until the hole is filled. The metal needle is now pulled from the hole leaving a small hole all the way to the blasting powder. A "squib" is placed in the hole and lit. The miner now has about 5 minutes to get to safety before the blast occurs.
