We measure air/flue gas paths of the boiler to the maximum temperature of the medium 500°C with velocity probes. In addition, we can also use an apparatus to measure emissions in the outgoing flue gases, for example, NOx, and CO.
By measurement, we can determine:
- velocity profile in the duct cross-section in the point of the network measurement
- real flow of the medium in the point of measurement
- ventilation of milling circuits at the outlet from classifiers
- correction coefficient, allowing to calibrate operating flow measurement of the specific medium
To measure the flow, we use:
- Prandtl tube: length 0.5 m, 1.0 m, 1.5 m, 2.0 m, and 2.5 m
- direct probe (S-probe): length 1.0 m, and 1.5 m
- micromanometers and manometers of the company AIRFLOW.
Other used measurement instruments:
- portable emission analyzer NOVA PLUS from the company MRU
- industrial endoscope Olympus IPLEX LX model IV
We collect samples of pulverized coal, fired in lignite and bituminous coal-fired boilers, by an isokinetic sampling probe and we can immediately analyze the granulometry of such collected pulverized coal by an analytical sieve shaker.
By sampling we can determine:
- weight distribution of the pulverized coal in the pulverized coal duct cross-section in the sampling point
- granulometric analysis of the collected pulverized coal
To collect pulverized coal and granulometry, we use:
- isokinetic sampling probe
- analytical sieve shaker AS 200 control
- precision balance KERN KB 3600-2N
