Development of sampling - measurement equipment for sec fuel/coal mixtures in power plant

Two water-cooled sampling probes - 3.5m an 4.5m long - were designed and manufactured. The first test of the probes were performed during full scale co-combustion experiments at Lagisza power plant.

One sampling probe enables two functions, depending on applied exchangeable probes tip:
- Deposit collection at given deposition surface temperatures
- Measurement of flue gas composition and temperature.

Temperature on the deposition surface of the first tip can be controlled in range of 500 degrees Celsius to 800 degrees Celsius by cooling air.

The second tip enables simultaneous measurement of gas temperature with suction pyrometer and flue gas composition.

Diameter and weight of the probe as well as water supplying hoses have been minimised in order to easier operation at power plants.

An experience from the power plant tests has been used for improvement of the probes and preparing their final version.
