Coal sampling and analysis standards 4 Abstract Each year, billions of tonnes of coal are traded in regional and international market for use in power generation, steel and cement making, and many other purposes. In commercial operations, the price of coal not only
power plant, less coal needs to be fired. This reduces the burden on the coal handling system, conveyers and crushers. Also, since dryer coal is easier to convey, this reduces maintenance costs and increases availability of the coal handling system. Crushed coal is fed into the bunkers from where it flows by gravity to the coal feeders.
