Document Type and Number:
Japanese Patent JP2022077260
Kind Code:
A
Abstract:
To detect a flame state in detail.SOLUTION: A flame detector 5 comprises a spectroscopic unit 521 that splits light of a flame into at least a first wavelength component and a second wavelength component, and a detection unit 527 that detects a temperature of the flame based on a comparison result between a strength ratio of the first wavelength component and the second wavelength component and a reference strength ratio that changes depending on a temperature.SELECTED DRAWING: Figure 2
