AM-EPRI2013, Advances in Materials Technology for Fossil Power Plants: Proceedings from the Seventh International Conference, 881-891, October 22–25, 2013,
... Abstract Oxyfuel combustion is considered as one of the most promising technologies to facilitate CO 2 capture from flue gases. In oxyfuel combustion, the fuel is burned in a mixture of oxygen and recirculated flue gas. Flue gas recirculation increases the levels of fireside CO 2 , SO 2 , Cl...

AM-EPRI2013, Advances in Materials Technology for Fossil Power Plants: Proceedings from the Seventh International Conference, 863-880, October 22–25, 2013,
... Abstract A combined pilot-scale combustion test and long-term laboratory study investigated the impact of oxy-firing on corrosion in coal-fired boilers. Four coals were burned under both air and oxy-firing conditions with identical heat input, with oxy-firing using flue gas recirculation unlike...

AM-EPRI2013, Advances in Materials Technology for Fossil Power Plants: Proceedings from the Seventh International Conference, 892-902, October 22–25, 2013,
... Abstract Using oxygen, rather than air, in coal-fired boilers has been studied for several years as a strategy to reduce NOx and concentrate CO 2 for capture. In combination with flue gas recirculation, higher levels of CO 2 are expected but increased H 2 O and SO 2 levels also may occur...

... to increase the carbon dioxide concentration. Cleaning and compression of the flue gas will prepare the carbon dioxide for pipeline transportation and deep well sequestration. The fuel dictates the type of gas recirculation system employed: cold, cool and warm. Hot gas recirculation is not a consideration...

... temperatures and pressures have increased. There are many benefits to increased thermal efficiency including the decrease in operating costs associated with purchasing coal, limestone for the flue gas desulfurization (FGD) unit, ammonia for the selective catalytic reduction (SCR) unit, reduced CO2 emissions...

... was extensively studied, it remains in the current time, especially in the water system of horizontal flue gas flow heat recovery steam generators. This may arise from the fact that this configuration of HRSGs is relatively new, and it is not thoroughly designed to cope with FAC. Not only the HRSGs in EGAT s...

... of different artificial gas and deposit mixes to simulate the environments expected in ultra-supercritical boiler service. EO.n supplied the coals in Table 1 and biomass for use by Cranfield. The Cranfield rig was modified to allow flue gasses to be recirculated - thus simulating oxyfuel firing - enhancing...

... corrosion that can exist within a fossil fuelled power plant. The figure shows how an oxide would form on the outer surface of the tube, on top of which you could expect to find deposits consisting of ash and alkali sulphates of varying composition. Assuming a flue gas temperature of approximately 1025 °C...
