ME 403. Power Plant Engineering Maj Najmus Saquib Sifat Military Institute of Science & Technology Fossil Fuels • The primary fuels used in thermal power plats are coal, fuel oil, and natural gas. • Other types of fuels that are burnt in TPP are saw-mill wood dust, rice husk etc. • These fuels may be used to boost one of the fossil fuels. This process is Coal grinding is preparatory process to a creating mixture for combustion in boilers at thermal power plants. To a high-quality fuel creation for the TPP units furnaces (fuel has the coal basis), needs to achieve the maximum material grinding degree and maximally reduce the coal dust moisture content.

Coal mill pulverizer in thermal power plants PPT SlideShare

3. 2.Coal pulverizer/mill system One of the critical power plant components that is relied upon to convert the energy stored in coal into electricity is the coal pulverizer or mill. The coal flow is controlled by the feeder, allowing coal to flow into the pulverizer mill. The pulverized coal and air mixture is then transport to the boilerIt can be seen from Table 1 that the coal-fired power plants are responsible for a large percentage of CO 2 emission among other process plants around the world, including Australia. About 46% of the world’s power generation is estimated to be from coal combustion, including 50%, 89% and 81% of the electricity generated in the A Review on Technologies for Reducing CO2 Emission from Coal
