The quality of a combustion process can be determined in light of the composition of the exhaust gases it produces. Combustion processes occur in the most various applications.
By firing plants or at engines a flue gas analysis reveals the concentration of carbon monoxide (CO) and oxygen (O2). Using fixed formula which e.g. refer to the ambient and gas temperature – the gas losses as well as the efficiency of a heating plant can be determined.
Nitric oxides in flue gas (NO + NO2) can either be measured and the results analysed.
Commonly the goals of a flue gas analysis are:
- Observance of legal prescriptions and limit values (i. a. acc. to 1st BImschV or TA Luft)
- Efficiency increase of the combustion process (= reaching with minimal ressources a targeted goal, it means a temperature, a heat performance, an engine performance, etc.)
- Costs savings achievable via combustible savings.
A flue (or combustion) gas analysis is performed by a flue gas analyser.
