Power generation industry studies have shown that coal pulverizers are an area where improved equipment reliability is badly needed. The Electric Research Institute (EPRI) has determined that 1% of plant availability is lost on average due to pulverizer-related problems.1 EPRI also identified oil contamination and excessive leakage as two
Thermal power plants use different types of coal pulverizers. The method used is attrition, impact, or a combination of both. This article explains the characteristics of the three main types- attrition, impact and attrition, and impact or hammer. Selection of the type of pulverizer depends on the grindability of the coal, the capital costs and maintenance costs, and considerations for licensing.

Coal is a combustible, sedimentary rock that, as a fossil fuel, is more abundant than either oil or gas. There are several varieties of coal, but the most abundant is Bitumus coal, which is used for power production and to make coke for steel production. Coal burning accounts for approximately 44% of the world's carbon emissions.
Coal for Power Plants. The 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.
This equipment is required to transport the coal stored on-site to the coal pulverizers. Because this equipment is essential to the operation of the power plant, it is critical that this equipment be free from contamination-related failure. Case Study. In March 2003, a major Canadian utility derated its Unit 4 due to a failure of the B mill.

And there are now 78 countries using coal power, up from 66 in 2000. Another 16 plan to join the club, notably Egypt and the United Arab Emirates. CO2 emissions from existing plants are enough to breach the carbon budget for 1.5 or 2C. These limits would mean no new coal plants and closing 20% of the fleet early, according to one recent study.
A conventional coal-fired power plant produces electricity by the burning of coal and air in a steam generator, where it heats water to produce high pressure and high temperature steam. The steam flows through a series of steam turbines which spin an electrical generator to produce electricity.
