Conversion of existing coal-fired power plants to oxyfuel combustion: Case study with experimental results and CFD-simulations

Application of lean flammability limit study and large eddy simulation to burner development for an oxy-fuel combustion system

“…Improving ignition performance leads to improved combustion performances including such items as, expanding the turn-down ratio, expanding the application fuel properties, maintaining safety of the fuel supplying system, improving the combustion efficiency, and reducing environmental pollutants such as NO x . Usually, for oxy-fuel combustion systems, a mixture of exhaust flue gas and oxygen is the combustion supporting gas (Tigges et al, 2009). Oxygen concentrations are usually variable for oxy-fuel combustion systems; therefore, ignition performances can be varied significantly.…”

“…Recently, development of oxy-fuel combustion technology has been particularly active using pilot-scale plants (Strömberg et al, 2009;Tigges et al, 2009). Fuel ignition properties are fundamental combustion performance parameters for engineering design of combustion systems.…”

Impact of stream impurities on compressor power requirements for CO2 pipeline transportation

“…Among several capture processes, oxy-fuel combustion is considered as one of the most promising options which enables capturing the vast majority of CO 2 from coal-fired power plants and can be retrofitted to the existing fleet of modern pulverised coal-fired power plants (Tigges et al, 2009). In the oxy-fuel capture, the fuel is burned in a mixture of purified oxygen and recycled flue gas from the boiler containing mainly CO 2 and water vapour .…”

Comparison of data-based methods for monitoring of air leakages into oxyfuel power plants

“…Utility boilers are usually operated with a slight under-pressure, which is also expected for future oxyfuel power plants (Tigges et al, 2009). Any air leakage into the system would result in a dilution of the flue gas by non-condensable gas components.…”
