power plant designs of boilers, which capture CO2 and achieve zero emission of all other pollutants. In oxyfuel combustion, the oxidant, air, is replaced by nearly pure oxygen from an air separation unit (ASU) and recycled flue gas to produce a flue gas stream, which is nearly all CO2 …Learn More
combustion to be injected with the Flue Gas Recirculation streams, and still maintain the oxygen concentration of around 25% O 2. Therefore, additional oxygen is required for combustion. Operation of the firing system using oxygen with Flue Gas Recirculation is the key boiler operating change associated with oxy-firing.Learn More
Flue gas is the gas exiting to the atmosphere via a flue, which is a pipe or channel for conveying exhaust gases from a fireplace, oven, furnace, boiler or steam generator.Quite often, the flue gas refers to the combustion exhaust gas produced at power plants.Its composition depends on what is being burned, but it will usually consist of mostly nitrogen (typically more than two-thirds) …Learn More

CECO CCA. - Model FGR -. Flue Gas Recirculation. Flue Gas Recirculation (FGR) is a powerful nitrogen oxide (NOx) control technique that significantly reduces NOx emissions by recirculating flue gases from the boiler exhaust duct into the main combustion chamber. This process reduces peak flame temperature and lowers the percentage of oxygen in Learn More

A 0.5 MW class oxy-fuel boiler was developed to capture CO2 from exhaust gas. We adopted natural gas as the fuel for industrial boilers and identified characteristics different from those of pulverized coal, which has been studied for power plants. We also examined oxy-fuel combustion without flue gas recirculation (FGR), which is not commonly adopted in power plant boilers.Learn More
