A simplified layout of a thermal power station is shown below. Coal: In a coal based thermal power plant, coal is transported from coal mines to the generating station. Generally, bituminous coal or brown coal is used as fuel. The coal is stored in either 'dead storage' or in 'live storage'. Dead storage is generally 40 days backup coal storage ...
1. Background and Motivation The total US CO2 emissions for 2006 were 5934 million metric tons (Mt). Of this, the electricity sector was responsible for 2344 Mt (%). Coalfired power plants produced 83% of the electricity sector's CO2 emissions, with most of the remaining emissions from natural gasfired power plants (EIA, 2007).

As the present study is focused on coalfired power plants, the performance of these kinds of power plants based on the energy and exergy viewpoints are sought in more detail here (Ali et al., 2021, He et al., 2021, Zhao et al., 2020b, Zhao et al., 2020a).
This is the simplified energy flow diagram of the coal fired power plant. Coal is a. flammable black hard rock used as a solid fossil fuel. It is made up of 65 95 % carbon and also. contains hydrogen, sulfur, oxygen and nitrogen. Therefore having a stored chemical energy on. itself.
A hybrid design that combines waste gasification and coalfired power generation has been proposed for improving the wastetoenergy process. In the integrated scheme, municipal solid waste is fed into the plasma gasifier and converted into syngas, which is precooled by the feedwater of the coal power plant and then conveyed directly into the coalfired boiler for combustion.

Coalfired power plants are the major source of CO 2 emission which contributes significantly to global climate change. An effective way to reduce CO 2 emission in coalfired power plants is postcombustion carbon dioxide (CO2) capture (PCC) with chemical absorption. The aim of this project is to carry out some research in model development,
Coal is the main source of electricity generation in fossil fuel based power plants. The use of coal in coalfired power plant (CFPP) causes raise in global temperature due to greenhouse gases emission responsible for global warming across the globe [1, 2]. It also has an adverse impact on the health of human being.
The application of oxyfuel combustion for coal fired power plant could be broadly classified according to: (a) oxyPC and (b) oxyCFB. On the other hand, the application of oxyfuel combustion for gas turbine based power plant could be broadly classified according to its working fluid namely: (a) CO 2 based GT cycles and (b) Water based GT cycles.
