Oxygen Control | CleanBoiler.org - Boiler Consortium

An electronic sensor is inserted into the boiler flue, near the boiler, ahead of any dampers or other sources of air leakage into the boiler or flue. The sensor is connected to a control panel that measures oxygen and sends a signal to a control damper on the burner air supply. From the Hays Cleveland OXY-MIZER™ data sheet:

Boiler Combustion | CleanBoiler.org

Flue gas recirculation technology can be classified into two types; external or induced. External flue gas recirculation utilizes an external fan to recirculate the flue gases back into the flame. External piping routes the exhaust gases from the stack to the burner. A valve controls the recirculation rate, based on boiler …

Coal-Fired Boiler - an overview | ScienceDirect Topics

Conventional PF coal-fired boilers, currently being used in the power industry, use air for combustion in which the nitrogen from the air (approximately 79% vol) dilutes combustion products such as CO 2 and water vapor in the flue gas. During oxyfuel combustion, a combination of oxygen (typically of greater than 95% purity) and recycled flue

2020-3-20 · Example - Oil Combustion and Heat Loss in the Flue Gas. If. the temperature difference between the flue gas leaving a boiler and the ambient supply temperature is 300 o C, and; the carbon dioxide measured in the flue gas is 10% - then, from the diagram above. the flue gas loss can be estimated to approximately 16%.
