In coal-fired power stations, the raw feed coal from the coal storage area is first crushed into small pieces and then conveyed to the coal feed hoppers at the boilers. The coal is next pulverized into a very fine powder. The pulverizers may be ball mills, rotating drum grinders, or other types of grinders.
Thermal-based power plants can produce electricity from coal or other fuel sources. The coal-fired process requires three different steps to turn energy released from burning coal to generating electricity for consumption. Coal fired power plants, while producing power, require a lot of water and produce a lot of pollutants like ash and CO2.

New coal-fired power plant design prioritises operational efficiency and emissions reduction. Julian Turner looks at lessons learned from China, pioneering technology in Denmark, Germany and Japan, and asks if ‘clean coal’ has a meaningful role to play in the future global energy mix.
In these modern designs, pollution from coal-fired power plants comes from the emission of gases such as carbon dioxide, nitrogen oxides, and sulfur dioxide into the air, as well a significant volume of wastewater which may contain lead, mercury, cadmium and chromium, as well as arsenic, selenium and nitrogen compounds (nitrates and nitrites).
Nearly 50% of the electricity generated in the world uses coal as the primary fuel. The function of the coal-fired thermal power plant is to convert the energy available in the coal to electricity. Coal power plants work by using several steps to convert stored energy in coal to usable electricity.
Second part is the steam cycle efficiency. Modern Rankine cycle, adopted in coal fired power plants, have efficiencies that vary from 32 % to 42 %. This depends mainly on the steam parameters. Higher steam perssure and temperatures in the range of 600 ° C and 230 bar have efficiencies around 42 %. We assume a value of 38 % for our case.

First, a brief introduction of FFPP fundamentals and con-
Almost two third of electricity requirement of the world is fulfilled by thermal power plants (or thermal power stations). In these power stations, steam is produced by burning some fossil fuel (e.g. coal) and then used to run a steam turbine. Thus, a thermal power station may sometimes called as a Steam Power

This information sheet describes the packaged equipment for a coal-fired steam power plant with the output capac-ity of 15 MW. Essentially, the package consists of three main components of power generating equipment; namely the boiler, steam turbine and generator; plus some auxiliary devices associated wit these main operating compnents.
When steam power plants are operating in grid demand mode, they are required to ramp up faster and more often than they were originally designed to—making real-time monitoring especially important. Our Digital Power Plant software interprets data from more than 10,000 sensors to improve coal-fired steam power plant performance. The result?

A boiler or Steam Generator (prime mover) is an integral device in a fossil fuel power plant used to produce steam by applying heat energy to water. A boiler incorporates a furnace in order to burn the fossil fuel (coal, gas, waste etc.) and generate heat which is transferred to water to make steam.
Advantages of coal-fired power plant: It’s known that coal is the most widely used fuels for generating power and electricity around the world which means that the coal_fired power plant has many advantages as: It’s abundant and easy to burn. It doesn’t depend on the weather or existing climatic conditions for mining coal.
Boilers for steam generation in power plants and process industries use coal as fuel. The percentage of boilers operating with coal as fuel outnumbers the boilers using all other fuels combined. Coal is pulverized before firing for achieving a stable and efficient combustion. Many types of pulverizers are used in boilers by different designers.
