Abstract
The invention belongs to combustor safety assurance devices, more particularly relates to a full automatic safety pilot burner used in combustors. The pilot burner is characterized in that an oblique channel is arranged inside a three-way connecting block and connected with an injection cylinder, through holes are arranged on the lateral surface of the injection cylinder, and a gas nozzle is connected under the through holes of the injection cylinder; a wind adjusting cylinder is sheathed outside the lower part of the injection cylinder, gaps are arranged between the wind adjusting cylinder and the injection cylinder and communicated with the through holes, and a wind adjusting nut is arranged under the wind adjusting cylinder on the gas nozzle. A nozzle injector leads gas overflowing from the through holes to be limited in the gaps between the wind adjusting cylinder and the injection cylinder and quickly led back by negative pressure inside the injection cylinder, thus avoiding gas leakage and improving safety. An ionization flame checking electrode is adopted for avoiding that the unexpected extinguishing of the pilot burner is hard to be found in time and improving safety. The wind adjusting nut can be used for controlling the mixture ratio between combustion air and gas and improving applicability.
