“…In the oxy-fuel combustion process, flue gas is generated at 20% of the amount compared to the classic air-fired combustion process. This case makes carbon capture easier and reduces the energy consumption of CO2 separation [8] [9]. Figure 1 shows the schematic of the oxy-boiler with flue-gas recycling.…”

“…This increase in combustion efficiency was higher for the anthracite coal type (Pang et al, 2020). Moon et al (2019) have examined the combustion properties of oxy-fuel combustion and air combustion processes in the circulating fluidized bed. They compared the carbon dioxide purity and emission amounts in the resulting flue gas.…”

“…As a result of this research, the oxy-fuel database, combustion properties, temperature and pressure profiles, solid suspension density, and CO2 purity, including emissions and combustion efficiency, were created. According to the results, it was observed that high CO2 concentration reduces the load of the CO2 purification unit, keeping pressure drop to a minimum in the circulating fluidized bed increases combustion efficiency, and flue gas feedback significantly reduces emissions (Moon et al, 2019).…”

Clean coal technologies are defined as applications that improve environmental acceptability and efficiency in producing, preparing and using coal. With clean coal technologies, it is possible to increase the amount of energy obtained per unit ton by reducing emissions and wastes. However, today there are strict sanctions that must be followed due to the legal regulations on the protection of the environment and combating climate change. At this point, the clean coal-burning technologies in which the oxy-fuel combustion process (with the possibility of CO2 storage) takes place come to the fore. In this study, the method of burning fuel with oxygen in a thermal power plant with a gross electricity generation of 500 MW was discussed. This thermal power plant model also has a fluidized bed dryer, a desulphurization plant, and a CO2 storage process. The combustion results of different properties of coals were examined, and their effect on operating parameters was investigated.

The aim of this paper is to specify the role of coal‐fired power plants (CFPPs) in the formation of global emissions/harmful pollutants and to discuss the benefits of current and future technologies to minimize environmental damage. In this regard, pollutant/emission reduction technologies from CFPPs are discussed in detail by considering the environmental and global warming aspects. Pollutant gases from CFPPs around the globe have always been the most important source of environmental concern in societies. In particular, due to the burning of the coal without taking the necessary precautions, the nitrogen in the coal and combustion air and the combustible sulfur components in the coal content are oxidized and released to the atmosphere as nitrogen oxides (NOx) and sulfur oxides (SOx). Another pollutant from power plants is carbon monoxide (CO). CO is a colorless, odorless, poisonous gas that can remain in the atmosphere for a long time. In addition, significant amounts of carbon dioxide (CO2) occur by virtue of the combustion of coal. CO2 emission is in the class of greenhouse gases causing global warming. As a result of this study, the factors causing the formation of harmful pollutants in CFPPs are determined and present and potential suggestions are provided for the environmental sustainability of such facilities. © 2020 Society of Chemical Industry and John Wiley & Sons, Ltd.
