This rock is then usually pulverized into a powder and then it is burned in a coal power plant. When coal is burned, there are tubes of water in the boiler and this water is heated and boils (see image below). When the water boils, it transforms into steam. The steam then turns a turbine attached to a generator and electricity is produced.

This chapter presents the recent research on various strategies for power plant flexible operations to meet the requirements of load balance. The aim of this study is to investigate whether it is feasible to integrate the thermal energy storage (TES) with the thermal power plant steamwater cycle. Optional thermal charge and discharge locations in the cycle have been proposed and compared.

The water heats up to nearly 400 degrees Fahrenheit (200 degrees Celsius) before returning to the surface. Once there, it transfers its heat to another liquid with a low boiling point, creating steam. The pressure of steam expanding spins a turbine to produce electricity like in a coal or natural gasfired plant.

It stands to reason that the less coal used per unit of electricity generated, the less CO2 is produced. One way to support the reduction of the amount of CO2 produced during this process is to improve the efficiency of the steam and gas turbines currently used in the generation process. These turbines convert the heat released (from burning ...

Simply put, coalfired electricity generation is a fivestep process: Thermal coal (either black or brown) that has been pulverised to a fine powder is burned. The resulting heat is used to turn water into steam. The steam at very high pressure is then used to spin a turbine, connected to an electrical generator.

The thermal energy stored in TES is normally absorbed from the working fluid of thermal power plants (, the superheated steam [26], [27] or hot water [28], [29]). However, large irreversibility exists in the heat exchange process between the steam and heat storage media due to the pinch point phenomenon [30].
