Measuring Correctly
“If you measure, you’re measuring nonsense”—this saying is often heard in technical circles. But we’re turning it on its head:
“If you measure correctly, you lay the foundation for sound decisions.”
In industrial and combustion plants, permanently installed measurement systems form the basis for daily operations. They provide the data used to control processes and monitor plants. However, measurements can be affected by unfavorable installation conditions, contamination, aging, or errors in measurement data conversion. As a result, the plant may not be operating at its optimal point.
A targeted measurement campaign can provide clarity, identify weak points, and uncover opportunities for optimization.
What is a measurement campaign?
During a measurement campaign, a selected parameter—such as temperature, pressure, fluid velocity, oxygen concentration, or heat transfer—is examined in detail using instruments specifically designed for that purpose. The goal is to obtain as accurate a picture as possible of the actual condition of the plant and to draw conclusions from the results for ongoing operations. The impetus for specific measurements often comes from unexpected data from operational measurements, inconsistent balances, or unexpectedly high consumption of operating materials.
The measurements are carried out by expert personnel from CONENGA Engineers at your thermal plant while it is in operation. Thus, such measurements do not cause any plant downtime and do not result in any additional effort on your part. After the measurement, the collected data is processed and interpreted. It forms the basis for process and control system optimizations. Measurement campaigns are therefore not an end in themselves. Similar to potential studies, they serve to identify specific measures for increasing efficiency, reducing costs, or improving process stability.
Case Study: SNCR System
A real-world example is the measurement of flue gas temperature in the first boiler pass of a thermal incineration plant. The investigation was prompted by an unusually high consumption of ammonia water in the SNCR system for nitrogen oxide reduction.
Our experts suspected that the reactant was being injected outside the optimal temperature range, thereby requiring a higher dosage. To test this hypothesis, a detailed temperature measurement was conducted across the entire cross-section of the boiler pass. Several sensors were used for this purpose, which recorded the absolute temperatures at the respective measurement points.
In addition, it was possible to determine and visualize the spatial temperature distribution within the boiler pass.
The measurements confirmed the hypothesis. It became apparent that the temperature distribution deviated significantly from previous assumptions. Based on the results, targeted and relatively cost-effective adjustments were proposed. This made it possible to sustainably reduce ammonia water consumption and improve the economic efficiency of plant operations.
Conclusion
Measurement campaigns provide a detailed record of the plant’s current status with respect to selected parameters. After the measurements are taken on-site by qualified personnel, the data is analyzed, allowing conclusions to be drawn that lead to more efficient operation of your thermal plant. Thus, such measurements are not an end in themselves, but rather provide the basis for decisions regarding specific measures that will optimize your plant.
