what is the use of coal-fired boilers


Rankine Cycle - Steam Turbine Cycle | Characteristics

Today, the Rankine cycle is the fundamental operating cycle of all thermal power plants where an operating fluid is continuously evaporated and condensed. It is the one of most common thermodynamic cycles, because in most of the places in the world the turbine is steam-driven.. In contrast to Carnot cycle, the Rankine cycle does not execute isothermal processes, because these must be performed

Carbon capture and storage - Wikipedia

Carbon capture and storage (CCS), or carbon capture and sequestration and carbon control and sequestration, is the process of capturing waste carbon dioxide (CO 2), transporting it to a storage site, and depositing it where it will not enter the atmosphere.Usually the CO 2 is captured from large point sources, such as a cement factory or biomass power plant, and normally it is stored under a

Pulverized coal-fired boiler - Wikipedia

A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels.
