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.

We are considering the analysis of a cumulative coal fired thermal power plant with all methods of the efficiency increasing technics like lowering the condenser pressure, superheating the steam to high temperatures, increasing the boiler pressure, reheat and regenerative Rankine cycle, as shown in Fig. continuous mass flow diagram for one unit of the power plant modeled in this study ...
Introduction. The fast growing economy in China results in large energy demand. According to the statistical data from National Energy Administration of China, China's coal consumption in 2014 was billion tons, comprising % of the total, as well as TW h of thermal power generation, accounting for % of the pollutions released during the burning process of coal ...
The coal is usually pulverized and then burned in a pulverized coalfired boiler. The furnace heat converts boiler water to steam, which is then used to spin turbines that turn generators. Thus chemical energy stored in coal is converted successively into thermal energy, mechanical energy and, finally, electrical energy .
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 ...
