    OPERATION 4.1 Working principle The gas sample is taken in through the fumes probe, by a diaphragm suction pump inside the instrument. The measuring probe has a sliding cone that allows the probe to be inserted in holes with a diameter of 11 mm to 16 mm and to adjust the immersion depth: the fumes picking point must be roughly in the centre of the flue section.

  • Page 85 Stack loss is calculated by applying a simple formula which relates it to other easily measurable parameters: Qs = A2 + B Tf-Ta Where: A2, B = factor that depends on the fuel used Tf = flue gas temperature Ta = combustion air temperature = % carbon dioxide in the flue gas Thus in order to calculate the stack loss and hence the thermal efficiency of a plant, one must measure the two temperatures (flue gas and air) and the level of carbon dioxide contained in the flue gas (% CO...

Oxygen O Chemist 400 The percentage of oxygen in air is around 21%: an ideal combustion process Serial: 421023 will “burn” all the oxygen present; in truth, however, the residual percentage is Memory: 01 never zero due to the presence of excess air.
  • Page 87 Instructions for accurate testing In order to achieve a certain degree of accuracy when conducting flue gas analysis, the following should be respected: the boiler being checked should be running in steady state conditions the flue gas analyser should be switched on at least 3 minutes before testing (time to auto-calibrate) with the probe located in fresh air the point in which the probe is inserted for analysis has to be at a distance of approximately twice the stack diameter or, alternatively, as directed by the boiler manufacturer.
