The Oxy-combustion burner development for the CO2 pilot at Lacq

Experimental investigation of structure and stabilization of spray oxyfuel flames diluted by carbon dioxide

“…Oxycombustion diluted by recirculating flue gases is one of the most advanced innovating combustion technique to adapt carbon capture and storage (CCS) to industrial combustion plants [1,2]. High efficiency of the CCS process behind the combustion chamber requires a large amount of CO 2 in flue gas, which is ensured by reinjection of CO 2 extracted from the stack, in the burner to dilute fuel and oxygen reactants.…”

Effect of the combustion system on reduction of thermal specific energy consumption in an industrial high temperature process

“…Even though the technology for oxy-combustion is well known, few works have been directed to analyze the effect of residence time of flue gases on the energy efficiency of high temperature processes where combustion with oxygen is used. Prieler et al [23] modeled an industrial walking hearth furnace for reheating of steel billets where oxygen enriched combustion with 25% O2 was applied. They determined 8% of fuel saving with oxygen enriched combustion.…”

Experimental and Numerical Investigations of Structure and Stability of Premixed Swirl-Stabilized CH4/O2/CO2 Flames in a Model Gas Turbine Combustor

“…Oxy-fuel combustion is such a promising method for controlling CO 2 emissions from power plants. This technique if merged with carbon capture and sequestration (CCS) technologies will facilitate the capturing process due to the high concentration of CO 2 in the exhaust stream. , The main challenge in this case is to retrofit the current air–fuel combustors with oxy-fuel burners at minimum required modifications and performance deficiency. In oxy-fuel power plants, oxygen separation units are commonly used to separate oxygen from air; however, these separation units consume a great portion of the output power for the separation of oxygen in oxy-combustion power plants .…”
