The measurements of smokiness of the flue gas in the exhaust duct of a power boiler

摘要

The paper presents a construction of an absorption instrument for measuring the flue gas smokiness. The instrument, which was tested in industrial conditions, is a probe of the diameter 51 mm and length 2000 mm inserted into the exhaust duct. A laser diode GaAs of the power 5 mW were used as a light source. The industrial testing was performed on Power Unit no. 10 in the power plant TUROW II in Turoszow.
