Thermal power plants (TPPs) are critical to supplying energy to society, and ensuring their safe and efficient operation is a top priority. To minimize maintenance shutdowns and costs, modern TPPs have adopted advanced fault detection and diagnosis (FDD) techniques. These FDD approaches can be divided into three main categories: modelbased, datadrivenbased, and statisticalbased methods ...
The flue gas desulfurization (FGD) process eliminates Sulphur dioxides from flue gas produced by the combustion of fossil fuels in furnaces, boilers, and other sources. Limestone is an essential element for the FGD process in coalfired thermal power plants. FGD system contributes efficaciously to the prevention of air pollution through its limestone/gypsum treatment in greater reliability ...
The pulverized coal is then blown into the furnace for combustion. Each type of roller mill has its own advantages and disadvantages, depending on factors such as coal quality, desired fineness, and plant layout. The choice of roller mill type is typically based on the specific requirements and conditions of the thermal power plant.

A coalfired power station or coal power plant is a thermal power station which burns coal to generate electricity. Worldwide there are over 2,400 coalfired power stations, totaling over 2,000 gigawatts capacity. [1] They generate about a third of the world's electricity, [2] but cause many illnesses and the most early deaths, [3] mainly from ...
The coal transport system of coalfired power plants is the most serious site of coal dust pollution in power plants. The coal entering the plant until it is sent to the boiler bunker of the plant has to go through several production links, such as unloading, transporting, storing, taking, crushing, and blending.
Monitoring and enforcing the performance of equipment in coalbased thermal power plants play a vital role in operational management. As the coalbased power plant is a nonlinear system involving multiple inputs and multiple outputs, the standard and typical identification methods tend to deviate. This can happen due to factors such as strong coupling, multivariable characteristics, time ...
