Coal fired power plants follow the Rankine cycle in order to complete this process. Since they require plenty of water to be circulated in this cycle, coal power plants need to be located near a body of water. The process of coal fired plants can be seen below in Figure 3. Figure 3.

How a Coal Plant Works. Coalfired plants produce electricity by burning coal in a boiler to produce steam. 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 water and returned to the boiler to start the process over. Here's a real ...

Steam coal, also known as thermal coal, is used in power stations to generate electricity. First coal is milled to a fine powder, which increases the surface area and allows it to burn more quickly. In pulverised coal combustion (PCC) systems, the powdered coal is blown into the combustion chamber of a boiler where it is burnt at high temperature.

2. Process description of a coalfired power plant. A coalfired power plant burns coal to produce electricity. In a typical coalfired plant, there are pulverisers to mill the coal to a fine powder for burning in a combustion chamber of the boiler. The heat produced from the burning of the coal generates steam at high temperature and pressure.

Once the power reaches its delivery point, it goes through a stepdown (or reduction of voltage) process at switching stations. Here the 115,000500,000 V is stepped down to approximately 115,00046,000 V before being sent to the first component of the distribution system—the substation and eventually to your home.

An integrated gasification combined cycle (IGCC) is a technology using a high pressure gasifier to turn coal and other carbon based fuels into pressurized gas—synthesis gas ().It can then remove impurities from the syngas prior to the electricity generation cycle. Some of these pollutants, such as sulfur, can be turned into reusable byproducts through the Claus process.

This rock is then usually pulverized into a powder and then it is burned in a coal power plant. When coal is burned, there are tubes of water in the boiler and this water is heated and boils (see image below). When the water boils, it transforms into steam. The steam then turns a turbine attached to a generator and electricity is produced. Coal ...
