CO2 capture and storage (CCS) is an effective method for achieving CO2 mitigation while simultaneously keeping energy supplies secure. To put CCS into practice, it is important to develop energyefficient industrial technologies for CO2 capture. In this work, a pilotscale demonstration of carbon capture from flue gas by adsorption technology was performed in an existing coalfired power plant ...

features of major types of coal used for power generation are listed in Table 1. Pulverised coal (PC) is the fuel used in about 97% of the world's coalfired capacity (IEA, 2008). In a pulverised coalfired power plant, coal is milled and burned with air in tall boilers that provide for complete burnout and efficient heat transfer.

Coalfired plants are the most widely used power plant today. They involve the combustion of coal producing high pressure (typically psig, ~165240 bar) and high temperature (>500ºC) steam which is used to drive a turbine at synchronous speed (3000 rpm in countries such as the UK with a 50 Hz supply frequency, 3600 rpm in ...

Looking at the change in the power sector from 2010 to 2020, there is a reduction in power generation by thermal coal plants. Reports indicate a 30% reduction in power generation from coal fired thermal plants [7, 16, 18]. This is aligned with the reduction of CO 2 released into the atmosphere from coal and gas plants [5, 12].

(d) Excludes the energy of the coal and natural gas to the power plant. (e) Includes the coal and natural gas fed to the power plant since these resources are consumed within the boundaries of the system. Because the energy in the coal is greater than the energy delivered as electricity, the life cycle efficiency is negative.
