Flame stabilizing device and engine

摘要

Problem to be solved: to provide a laser flame stabilizing apparatus capable of relaxing the flow rate reducing effect of the combustion gas than in the prior art.Solution: the light irradiation means 5C and 9b are provided with light irradiation means 5C and 9b for irradiating the laser beam to the flame formed in the combustion field 5a, and the light irradiation means 5C and 9b comprise a condensing optical system for condensing the laser beam into the flame. Further, when the flame is formed in a plurality of combustion chambers 5a, the laser irradiator 59b 9b irradiates the plurality of flames with laser light, and the condensing optical system is provided for each of several flames.Diagram
