2. Process description of a coalfired power plant. A coalfired power plant burns coal to produce electricity. In a typical coalfired plant, there are pulverisers to mill the coal to a fine powder for burning in a combustion chamber of the boiler. The heat produced from the burning of the coal generates steam at high temperature and pressure.
Coalfired power plant with postcombustion CO 2 capture plant model development and incorporated with a neural network inverse control system: Simulation scenarios of power set point variations were simulated showing that fluegas and steam extraction for the reboiler is the most crucial interaction between the two plants.
As this diagram shows, the plant operates on the same principles as other fossilfueled electric generating plants—it burns coal to produce heat that turns water into steam, which then turns turbines in a generator. Sources/Usage: Public Domain. Credit: Georgia Power
The fire inside the boiler is initially started by injecting fuel oil at a high pressure into the furnace through nozzles. The oil is atomised and then ignited with a propane gas ignition system. The temperature inside the furnace is ± 1200oC at full load.

For the top cycle, the CO 2 flow stream after hightemperature recuperator (HTR) enters the boiler and converts thermal energy into power by three turbines (T1T3). Then lowpressure CO 2 from the outlet of T3 transmits heat to highpressure CO 2 through HTR and LTR (lowtemperature recuperator). Here the following flow assignment should be highly focused due to the unique characteristics of ...
As the flue gas flow diagram of the thermal power plant shows, after the combustion process, the flue gas which has a sufficient quantity of heat is made to pass boiler tubes, dust collectors, economizers, and Preheater before passing out through a chimney. The water and air get preheated by passing the flue gas around the economizer and Preheater.

Stage 1 The first conversion of energy takes place in the boiler. Coal is burnt in the boiler furnace to produce heat. Carbon in the coal and Oxygen in the air combine to produce Carbon Dioxide and heat. Stage 2 The second stage is the thermodynamic process. The heat from combustion of the coal boils water in the boiler to produce steam.

The work of the coal power plant begins with the arrival of coal from the coal mines via trains. This coal is then transported to the power plant to be converted into a powder form.
In both cases a power source is used to turn a propellerlike piece called a turbine, which then turns a metal shaft in an electric generator, which is the motor that produces electricity. A coalfired power plant uses steam to turn the turbine blades; whereas a hydroelectric plant uses falling water to turn the turbine. The results are the same.
