Flue Gas & Its Part in Global Warming


When fuels are burned there remains, besides ash, a certain number of gas components. If these still contain combustion heat, they are called heating gases. As soon as they have conveyed their energy to the absorbing surfaces of a heat exchanger, they are called flue or stack gases.

Its composition depends on what is being burned, but it usually consists of mostly nitrogen (typically more than two-thirds) derived from the combustion air, carbon dioxide (CO2) and water vapor as well as excess oxygen (also derived from the combustion air).

It further contains a small percentage of pollutants such as particulate matter, carbon monoxide, nitrogen oxides and sulfur oxides.


Carbon dioxide (CO2)—the primary greenhouse gas responsible for global warming—along with other pollutants.

The algae uses Photosynthesis to combine water and the CO2 in the flue gas to grow additional algae and form oxygen and water vapor.  The organisms also absorb nitrogen oxide and sulfur dioxide, which contribute to acid rain.

The research Academy of Sciences of the Czech Republic and Fuel Research Institute  conducted a research on the Utilization of flue gas for cultivation of microalgae Chlorella spp.,  in an outdoor open thin-layer photobioreactor. In this, Flue gas generated by combustion of natural gas in a boiler was used for outdoor cultivation of Chlorella sp. in a 55 m2 culture area photobioreactor. It was estimated that about 50% of flue gas decarbonization can be attained in the photobioreactor.
