Coal fired power plants are heavily used due to large and long lasting coal resources compared with oil or natural gas. An important bottleneck in the operation of this particular kind of plants, however, is the coal pulverization process, which gives rise to slow take-up rates and frequent plant shut-downs (Rees & Fan, 2003).In typical coal fired …

Pulverizers / Mills. Reliable coal pulverizer performance is essential for sustained full-load operation of today's power plants. An effective pulverizer must be capable of handling a wide variety of coals and accommodating load swings in utility boilers as large as 1,300 MW. B&W's pulverizers, found at power stations throughout the world.

How a Coal Plant Works. Coal-fired 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.

Controllers for the coal mill are designed in (Rees and Fan 2003) and (Hasselbacher et al. 1992). High order dynamic models and observer design for coal mills 177 IFAC Symposium on Power Plants and Power Systems Control, Kananaskis, Canada, 2006 are the topics in (Fukayama et al. 2004).

Figure 1 shows the basic principle of combustion-based power generation using a steam turbine. Combustion of the fuel generates heat that is used to convert water pumped to high pressure into high pressure superheated steam, which is then used to drive a turbine. The turbine drives a generator.

Sulfur in coal can affect power plant performance in several ways. Sulfur in the form of pyrite (FeS 2) can lead to spontaneous combustion and contributes to the abrasion in coal mills; therefore, if a lower quality coal containing pyrite

Coal quality, that is the properties of coal, has an impact on many parts of a power plant including the coal handling facilities, pulverising mills, boiler, air heater, ESP, ash disposal as well as stack emissions. Coals have different characteristics and heat content.

Coal Mills are used to pulverize and dry to coal before it is blown into the power plant furnace.. Operation. The coal is feed into the coal mill through a central inlet pipe where gravity is used to lead the coal to the bottom of the mill, where the grinding table and some heavy rollers pulverizes the coal to particles.
