Why Pulverized Coal is Used in a Power Plant - Bright Hub ... CachedCoal For Power PlantsWhy Pulverizing ?GrindabilityThe coal fired power plant converts energy in coal to electricity. The basic input into the system is the fuel that is coal. All other systems and equipment only aid in this conversion process. Before going into the details, let us look at the quantity of coal processed in a power plant. A 2000 MW power station could be handling coal in the range of 1600 tons/hr or around 12 million tons of coal annually. A single 500 MW unit consumes in the range of 400 tons/hr of coal. The coal input to the boiler of the power plant passes through three different phases before combustion in the boiler. 1. Receiving, storing, and transporting the coal to the boiler. This is bulk storage and bulk handling. 2. Preparing the coal for firing or pulverizing. This is what is special in a coal fired power plant, especially large thermal power plants. 3. Burning the coal in the combustion process to release the energy in the fuel. See full list on brighthubengineering.com The basic requirement of coal combustion is that all the carbon particles in coal should get sufficient air to burn and release the heat. Coal normally is available to power plants in large lumps ranging from 2 mm to 50 mm size. Coal is commercially available in different sizes known as “Run of Mine,” “stoker,” “slack,” etc. depending on their size. In the olden days, coal burning was done on grates without any change in size or pulverizing. Because of the large size of coal, some of the carbon particles do not come in contact with the air. These unburned carbon particles go out with ash. This is a loss and could be in the range of 5 % or greater in the older grate-fired combustion. Modern boilers powder the coal to a very fine dust so that while burning, it is almost like a fluid stream. The size of the coal particles is in the range of 75 microns. This means every particle comes into contact with the air. The loss due to unburned carbon is only in the range of 0.5 % or less making... See full list on brighthubengineering.com There is one important characteristic of coal that decides the type, size, and power required for pulverizing. This is the grindability of coal and is denoted by the Hardgrove Grindability Index or HGI . Grindability in general is a function of the grade of coal. 1. Sub-bituminous coal from the Indian sub-continent has an index near fifty. A higher number indi es the coal is soft and easy to grind. 2. Anthracitic coals, higher grade coals, have higher hardness and consequentially a lower Grindability Index in the range of forty or less. 3. Lignite, the lower grade of coal, on other hand is very soft and easy to pulverize and can have an index of a hundred and greater. The Grindability Index decides what type of pulveriser to use and the power requirement for pulverizing. See full list on brighthubengineering.com

Pulverized Coal Power Plant Coal Energy CachedJan 04, 2011 · Pulverized Coal Power Plant Coal Energy. For use in thermal power plants, coal is ground into dust using a device called a powdered coal mill. The resulting product, called powdered coal or pulverized coal, is then generally used in a fossil fuel power plant for electricity generation. Pulverised coal is a significant dust explosion hazard, as large quantities are suspended in air for transfer from the mill to the power plant.

Coal fired power plant - Energy Edu ion CachedPurposeExampleEnvironmentUseSafetyResourcesCoal fired power plants are a type of power plant that make use of the combustion of coal in order to generate electricity. Their use provides around 40% of the world& 39;s electricity and they are primarily used in developing countries. 2 Countries such as South Africa use coal for 94% of their electricity and China and India use coal for 70-75% of their electricity needs, however the amount of coal China uses dwarfs most other countries see the data visualization below . 3 The use of coal provides access to electricity to those who previously didn& 39;t have it, which helps to increase quality of life and reduce poverty in those regions, however it produces large quantities of different pollutants which reduces air quality and contributes to climate change. See full list on energyedu ion.ca Coal plants require enormous amounts of coal. Shockingly: a 1000 MWe coal plant uses 9000 tonnes of coal per day, equivalent to an entire train load 90 cars with 100 tonnes in each . 4 The amount of coal used during a full year would then require 365 trains, and if each is 3 km long then a single train carrying all of this coal would need to be about 1100 km long; about the same distance as driving from Calgary AB to Victoria BC. If this train were to pass by your house at 40 kilometers per hour, it would take more than a day to pass The conversion of this coal to the end goal of electricity is a multi-faceted process: 6 See full list on energyedu ion.ca Coal power plants have many associated environmental impacts on the local ecosystem. The burning of coal releases many pollutants - oxides of nitrogen NOx and sulfur SOx - and particulate matter. They also emit greenhouse gases, such as carbon dioxide CO2 and methane CH4 , which are known to contribute to global warming and climate change. To help stunt the emission of these, power plants require technology to reduce the output of these harmful molecules. 9 When power plants remove water from the environment, fish and other aquatic life can be affected, along with animals relying on these sources. 10 Pollutants also build up in the water that power plants use, so if this water is discharged back into the environment it can potentially harm wildlife there. 10 See full list on energyedu ion.ca Large quantities of water are often needed to remove impurities from coal, 10 in the process is known as coal washing. For instance, in China, around one-fifth of the water used in the coal industry is used for this process. 11 This process helps reduce air pollution, as it eliminates around 50% of the ash content in the coal. This results in less sulfur dioxide SOx being produced, along with less carbon dioxide CO2 due to higher thermal efficiencies. 9 See full list on energyedu ion.ca The discharge of water from the power plants and coal washing requires monitoring and regulation. Visit the US Environmental Protection Agency EPA for more information on this.
