Flue Gas Recirculation: History and Uses - EnviroPow

Jun 19, 2019· Flue Gas Recirculation (FGR) is the process of taking a portion of the flue gas from a combustion process and recirculating it back through a boiler or burner. When the process is used in internal combustion engines it is commonly referred to as exhaust gas recirculation (EGR).

Low Temperature Corrosion in Boiler and Its Preventi

Condensation of these acids results in metal wastage and boiler tube failure, air preheater corrosion, and flue gas duct corrosion. In order to avoid or reduce the cold end corrosion the gas temperature leaving the heat transfer surface in boiler is kept around 150 degrees centigrade, ranging from 120 to 155.


the resistivity of fly ash after coal-fired boilers varies with the flue gas temperature. the normal esp operating temperature of around 150°C is typically near the maximum resistivity of the ash

Flue gas composition is significantly affected by the combustion conditions. Concentration of gaseous species upon firing 1.7% S coal (chemical composition is given in Table 1) was calculated at 1300 °C, assuming thermal equilibrium, and presented in Figure 2 as a function of air–fuel ratio. In this chapter, air–fuel ratio is defined by the ratio of their weights; air–fuel ratio of 10

Performance study and application of new coal-fired boil

The recovery of heat from the flue gas is an effective way to improve the thermal efficiency of a boiler. In a coal-fired boiler with wet-desulphurization, a portion of the flue gas thermal energy is used for the latent heat process, which leads to temperature reduction and humidity increase.
