Not only in industry, but also in the field of communal power and heat supply, gas turbines have proven themselves as reliable and crucial components in combined heat and power plants (CHP), for example, or combined gas and steam power stations. The optimally adjusted operating parameters of a gas turbine are a deciding factor in whether the respective plant really works efficiently, productively and economically.
The complex interrelationship between the exhaust gas parameters and the adjustment of the combustion process forms the basis for an optimum performance. For this reason, it is important for efficient operation to have a reliable, highly precise measuring instrument to hand.
Good for the climate. And for the balance sheet.
Reducing emissions and energy costs
For emission measurements on gas turbines, very low as well as very high gas concentrations have to be measure.
Very low CO and NOx emissions at the correct adjustment and the right operating point of the gas turbine:
In order to achieve as high a measurement accuracy as possible, the influencing factor of the exhaust gas humidity must be reduced. This includes above all the dilution of the exhaust gas parameters by a high exhaust humidity (gaseous state) as well as leaching due to chemical reactions between the exhaust gas parameters and condensate (liquid state).
Very high gas concentrations when starting up the plant and at differing load level:
During this procedure, a gas concentration peak can occur, which cannot be compensated by a low-sensor without dilution.
High-precision emission measurements with the testo 350
High measurement accuracy at low concentrations, thanks to precise COlow and NOlow sensors
Measure high concentrations and peaks without additional sensor thanks to measuring range extension and sensor protection
Integrated gas preparation protects from dilution of the measurement values by humidity and from leaching out, e.g. of NO2 by condensate in the exhaust gas
Ready to measure in 30 seconds
Easy, precise test gas adjustment on site by the user
Even a reduction in excess air by 1% and an increase in efficiency by 1% can have a significant impact: With monthly fuel costs of 15 million euros, this can save up to 150,000 euros. This shows how crucial even small optimizations are for cost efficiency and environmental protection.
