Despite the historical tightening of emission constraints from coalfired power plants, its use for power generation has been on the increase mainly due to its availability, cost and the ever increasing global energy demand [2], [3], [4]. This shows that coal will continuously play a major role in meeting the global energy need.

Coal fired power plants follow the Rankine cycle in order to complete this process. Since they require plenty of water to be circulated in this cycle, coal power plants need to be located near a body of water. The process of coal fired plants can be seen below in Figure 3. Figure 3. The process of a coal fired power plant to convert coal into ...

Thermal power generation is economical in the current scenario, but it is a waterintensive process, resulting in a highwater footprint. In this research, life cycle water use (LCWU) was assessed for three coalbased thermal power plant in India. The LCWU was found to be in the range of to LkWh−1. The results of the LCWU of coalbased thermal power plants in India are higher than ...

Fossil fuel power plants generate significant amounts of CO 2 emissions into the atmosphere, which are believed to be the main cause of climate change. Among CO 2 mitigation options, carbon capture and storage is considered the only technology that can significantly reduce the emissions of CO 2 from fossil fuel combustion sources. There are mainly three technological routes for CO 2 capture ...

A combined cycle power plant based on the SWCG has also been proposed [36], where the reaction heat of the coal gasification process is supplied by coal combustion with air outside the GF, avoiding pure oxygen combustion and thus eliminating the ASU. The results showed that the thermal efficiency is further improved and reaches %.
