Sulfur dioxide. SO2 is a colorless gas with a pungent odor and is primarily associated with oil- and coal- burning appliances. At low levels of exposure, SO2 can cause eye, nose, and respiratory tract irritation. At high exposures, it can cause the airways to narrow, leading to chest tightness and breathing problems.
Nov 05, 2019 · Without a boiler flue, there's every chance that you could be exposed to harmful gases. There's also the environmental impact to consider. When fitting boiler flues, there are strict criteria in place to ensure that combustion fumes and hazardous gases are released into the atmosphere safely.

Aug 22, 2019 · One of the gases your boiler flue pipe will disperse outside is carbon monoxide, which is potentially very harmful. This is why it's so important to have a boiler flue correctly installed, in line with gas safety regulations.
A typical flue gas from the combustion of fossil fuels contains very small amounts of nitrogen oxides (NOx), sulfur dioxide (SO 2) and particulate matter. The nitrogen oxides are derived from the nitrogen in the ambient air as well as from any nitrogen-containing compounds in the fossil fuel.
MSW contains corrosive and toxic acid gases, such as hydrogen chloride (HCl), hydrogen fluoride (HF), sulphur dioxide (SO 2) and nitrogen oxides (NO x). The removal of these gases from the flue gas stream is relatively simple and very efficient. • Heavy metal compounds.
The two main gases your gas condensing boiler produces are water vapour and carbon dioxide. Nitrogen oxide can also be created when the oxygen and nitrogen in the air are burned together. If your boiler isn't burning the gas correctly, carbon monoxide could be produced too. Boilers are made to be safe, and these gases shouldn't harm you.

Feb 01, 2017 · Biomass-based fuels have a different chemical composition than fossil fuels such as coal. Biomass fuels typically contain more alkali metals and chlorides,, which can, in the combustion process, be vaporized into the flue gas. For instance, alkali chlorides …
