How Does a Coal Power Plant Work?

Thermalbased power plants can produce electricity from coal or other fuel sources. The coalfired process requires three different steps to turn energy released from burning coal to generating electricity for consumption. Coal fired power plants, while producing power, require a lot of water and produce a lot of pollutants like ash and CO2.

What Are the Four Stages in Coal Formation? Reference.com

The four stages in coal formation are peat, lignite, bituminous and anthracite. Each of these stages must be completed for coal to form. Stage one in coal production is peat. Peat is a fibrous substance that is oxidized by water and carbon dioxide. When a plant dies, and stays under water, it builds up an accumulation of peat.

What are the different types of coal? American

The coal formation process involves the burial of peat, which is made of partly decayed plant materials, deep underground. The heat and pressure of burial alters the texture and increases the carbon content of the peat, which transforms it into coal, a type of sedimentary rock. This process takes millions of years. Types, or "ranks," of coal are determined by carbon content.
