The Benefits of an Integrated Analyzer Concept
The most important area of applications for continuous gas analysis. Combustion processes can be found in many different industrial areas,
COMBUSTION PROCESSES • the generation of heat
• and electricity,
• Process steam production,
• Municipal and hazardous waste incineration,
• Surface treatment for example in annealing processes,
• Melting processes as used in metal or glass production,
• Roasting process for example iron ore roasting, sintering,
• Steel production and
• Cement production, … to name only the most important.
• CO2, H2O, N2 expected
• CO, HC, excess O2 incomplete combusion
• SO2, NOx Sulfur in fuel, N2
• HCl, HF (Waste Incin)
• Hg, Particulates
Combustion efficiency Ideal combustion needs the right amount of oxygen.
The oxygen value can be measured with a paramagnetic oxygen analyzer
Efficiency of DeNOx process Nitrogen oxide and nitrogen dioxide are a major cause for environmental damage.
These components are removed by injection of ammonia.
The injection of ammonia is regulated via the NO/NO2 concentration in the exhaust gas. The efficiency of this process is controlled by monitoring the outlet for excess ammonia. Analyzers used are infrared photometer
Infrared for NO or alternatively ultra-violet photomete for NO and NO2, and laser
analyzer for NH3 measurement.
Electrostatic precipitator The typical measuring component is carbon monoxide.
Since CO is a flammable gas this measurement represents a safety measurement to avoid explosions.
Infrared photometer.
Efficiency of the DeSOx process (desulfurization) The efficiency of the flue gas desulfurization is monitored
by measurement of SO2 with Infrared.
