Flue Gas Recirculation (FGR) - CCA Combustion Systems

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 the combustion air/flue gas mixture, thereby

Flue-Gas Desulphurization - an overview | ScienceDirect Topics

Nicholas P. Cheremisinoff, in Clean Electricity Through Advanced Coal Technologies, 2012 2.5 Flue-Gas Desulfurization Material. Flue-gas desulfurization (FGD) material is a product of a process typically used for reducing SO 2 emissions from the exhaust gas system of a coal-fired boiler. The physical nature of these materials varies from a wet sludge to a dry, powdered material depending on

Flue-gas stack - Wikipedia

A flue-gas stack, also known as a smoke stack, chimney stack or simply as a stack, is a type of chimney, a vertical pipe, channel or similar structure through which combustion product gases called flue gases are exhausted to the outside air. Flue gases are produced when coal, oil, natural gas, wood or any other fuel is combusted in an industrial furnace, a power plant's steam-generating boiler
