Abstract
A detection apparatus (10) for detecting a backfire in a combustion chamber (31) that burns fuel supplied from a plurality of supply ports includes a light source (12) that outputs incident light to an optical fiber (11) laid around the plurality of supply ports, a converter (13) that receives returned light from the optical fiber (11) and converts the received returned light into an electric signal, a calculator (14) that analyzes the returned light converted into an electric signal and calculates a temperature at a predetermined position of the optical fiber (11), and a detector (15) configured to detect a backfire in the combustion chamber (31) based on the calculated temperature.
Claims11
A detection apparatus for detecting a backfire in a combustion chamber that burns fuel supplied from a plurality of supply ports, the detection apparatus comprising:
- a light source configured to output incident light to an optical fiber laid around the plurality of supply ports;
