Electrostatic Precipitator (ESP) – Construction and Working Principle

Electrostatic Precipitator (ESP) – Construction and Working Principle: Electrostatic Precipitator is located between the boiler and the chimney, it extracts the fly ash from the flue gases and thus prevents the fly ash from entering the atmosphere. Electrodes are used to attract the fly ash when the flue gas coming out of the boiler is …

Pressurised Fluidised Bed Combustion System (PFBC)

Pressurised Fluidised Bed Combustion System (PFBC): Pressurised Fluidised Bed Combustion (PFBC) system is used for large coal burning applications. The operating efficiency of PFBC is increased by introducing differential air pressure. In PFBC, coal is injected into pressurized bed of 850 – 900°C. The bed consists of 90 – 95% of coal ash and desulphurisation …
