It is formed from plant remains that have been compacted, hardened, chemically altered, and metamorphosed by heat and pressure over geologic time.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter wp-image-5312 size-full\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/02\/1280px-Coal_fired_power_plant_diagram.svg_.png\" alt=\"How Does Coal Energy Work\" width=\"1280\" height=\"794\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/02\/1280px-Coal_fired_power_plant_diagram.svg_.png 1280w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/02\/1280px-Coal_fired_power_plant_diagram.svg_-300x186.png 300w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/02\/1280px-Coal_fired_power_plant_diagram.svg_-1024x635.png 1024w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/02\/1280px-Coal_fired_power_plant_diagram.svg_-768x476.png 768w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/02\/1280px-Coal_fired_power_plant_diagram.svg_-696x432.png 696w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/02\/1280px-Coal_fired_power_plant_diagram.svg_-1068x662.png 1068w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/02\/1280px-Coal_fired_power_plant_diagram.svg_-677x420.png 677w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/02\/1280px-Coal_fired_power_plant_diagram.svg_-356x220.png 356w\" sizes=\"(max-width: 1280px) 100vw, 1280px\" \/><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Where_Does_Coal_Energy_Come_From\"><\/span><strong>Where Does Coal Energy Come From?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Coal is a non-renewable energy source because it takes millions of years to create. If you wonder how is coal formed, the energy in <a href=\"https:\/\/en.wikipedia.org\/wiki\/Coal\" target=\"_blank\" rel=\"noopener\" data-schema-attribute=\"\">coal<\/a> comes from the energy stored by plants that lived hundreds of millions of years ago when the earth was partly covered with swampy forests. For millions of years, a layer of dead plants at the bottom of the swamps was covered by layers of water and dirt, trapping the energy of the dead plants. The heat and pressure from the top layers helped the plant remains to turn into what we today call coal.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Coal_Mining\"><\/span><strong>Coal Mining<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Most coal is buried under the ground. If coal is near the surface, miners dig it up with huge machines. First, they scrape off the dirt and rock, then dig out the coal. This is called surface mining. After the coal is mined, they put back the dirt and rock. They plant trees and grass. The land can then be used again. This is called reclamation. If the coal is deep in the ground, tunnels called mine shafts are dug down to the coal. Machines dig the coal and carry it to the surface. Some mine shafts are 1,000 feet deep. This is called deep mining, or underground mining.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-5314\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/02\/Db1OiIRuer3CCLYhGggM_9c60f0031161edce4231dfbb04225a80.jpg\" alt=\"Coal Energy Work\" width=\"2087\" height=\"1130\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/02\/Db1OiIRuer3CCLYhGggM_9c60f0031161edce4231dfbb04225a80.jpg 2087w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/02\/Db1OiIRuer3CCLYhGggM_9c60f0031161edce4231dfbb04225a80-300x162.jpg 300w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/02\/Db1OiIRuer3CCLYhGggM_9c60f0031161edce4231dfbb04225a80-1024x554.jpg 1024w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/02\/Db1OiIRuer3CCLYhGggM_9c60f0031161edce4231dfbb04225a80-768x416.jpg 768w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/02\/Db1OiIRuer3CCLYhGggM_9c60f0031161edce4231dfbb04225a80-1536x832.jpg 1536w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/02\/Db1OiIRuer3CCLYhGggM_9c60f0031161edce4231dfbb04225a80-2048x1109.jpg 2048w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/02\/Db1OiIRuer3CCLYhGggM_9c60f0031161edce4231dfbb04225a80-696x377.jpg 696w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/02\/Db1OiIRuer3CCLYhGggM_9c60f0031161edce4231dfbb04225a80-1392x754.jpg 1392w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/02\/Db1OiIRuer3CCLYhGggM_9c60f0031161edce4231dfbb04225a80-1068x578.jpg 1068w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/02\/Db1OiIRuer3CCLYhGggM_9c60f0031161edce4231dfbb04225a80-1920x1040.jpg 1920w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/02\/Db1OiIRuer3CCLYhGggM_9c60f0031161edce4231dfbb04225a80-776x420.jpg 776w\" sizes=\"(max-width: 2087px) 100vw, 2087px\" \/><\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_Does_A_Coal_Power_Plant_Work\"><\/span><strong>How Does A Coal Power Plant Work?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>To answer how coal energy work, it is better to have a look at coal power plants. The principle is simple. After coal comes out of the ground, it typically goes on a conveyor belt to a preparation plant that is located at the mining site. The plant cleans and processes coal to remove dirt, rock, ash, sulfur, and other unwanted materials, increasing the heating value of the coal. Coal power plants produce electricity by burning coal in a boiler to produce steam.<\/p>\n<p>The steam produced under tremendous pressure flows into a turbine which spins a generator to create electricity. The steam is then cooled, condensed back into the water, and returned to the boiler to start the process over.<\/p>\n<p>The process of converting coal into electricity has multiple steps. If you are interested in how coal produce electricity step by step, the steps are the following:<\/p>\n<ol>\n<li>A machine called a pulverizer grinds the coal into a fine powder.<\/li>\n<li>The coal powder mixes with hot air, which helps the coal burnt<br \/>\nmore efficiently, and the mixture moves to the furnace.<\/li>\n<li>The burning coal heats water in a boiler, creating steam.<\/li>\n<li>Steam from the boiler spins the blades of an engine called a turbine, transforming heat energy from burning coal into mechanical energy that spins the turbine engine.<\/li>\n<li>The spinning turbine is used to power a generator, a machine that turns mechanical energy into electric energy. This happens when magnets inside a copper coil in the generator spin.<\/li>\n<li>A condenser cools the steam moving through the turbine. As the steam is condensed, it turns back into water.<\/li>\n<li>The water returns to the boiler and the cycle begins again.<\/li>\n<\/ol>\n<p>When coal is burned, this results to waste gases that contain sulfur and nitrogen oxide. These wastes become acid rain when mixed with atmospheric water and can pollute the air. Despite the disadvantages of coal, it remains to be a necessity for mankind. What is important is to think of alternative ways to produce energy while minimizing the bad effects of coal. You may wonder What are the coal energy advantages and disadvantages.
