Claims17
A gas component measuring device comprising:
- a cyclone including a gas inlet;
- and
- a laser gas analyzer configured to take, in the cyclone, a measurement of a component of a subject gas that contains particulate matter and is introduced into the cyclone through the gas inlet, wherein:
- the cyclone includes a pair of opening portions, opposed to each other, in a side surface thereof;
- a light emitting portion of the laser gas analyzer is disposed to emit laser light into the cyclone through one of the pair of opening portions, and a light receiving portion of the laser gas analyzer is disposed to receive the laser light that exits through the other of the pair of opening portions;
- and
- the gas component measuring device further includes a displacing device configured to reduce the particulate matter on an optical path of the laser light by hindering passage of the particulate matter in a vicinity of each of the pair of opening portions within the cyclone.
