Abstract

The invention provides an ignition nozzle device capable of improving the ignition stability. The ignition nozzle device comprises a nozzle wall cylinder and a nozzle pipe, wherein a combustion chamber is formed in the nozzle wall cylinder; the nozzle wall cylinder comprises a front end and a rear end which are oppositely arranged along the axial direction; the nozzle pipe is mounted at the front end of the nozzle wall cylinder, communicates with the combustion chamber, and is used for igniting a to-be-ignited device; a fuel gas nozzle used for injecting fuel gas into the combustion chamber is arranged on the nozzle wall cylinder; the mounting position of the fuel gas nozzle is close to the rear end; and the injection direction of the fuel gas nozzle is deviated from the diameter direction of the nozzle wall cylinder at the mounting position of the fuel gas nozzle, so that a rotating fuel gas flow field can be formed by the fuel gas injected by the fuel gas nozzle in the combustion chamber. The ignition nozzle device provided by the invention is simple in structure, ingenious in design, convenient to mount, high in practicability, and suitable for popularization and application.

Description

technical field [0001] The invention relates to an ignition nozzle, in particular to an ignition nozzle device capable of improving ignition stability. Background technique [0002] Most of the current ignition nozzles are fed with fuel, such as gas, into the combustion chamber first, so that the gas and air are mixed and burned, so as to ignite the device to be ignited, such as the combustion chamber of a gas turbine. In order to fully mix the gas and air, the ignition device is arranged with a long length in the longitudinal direction, and the mixing time is long. If the longitudinal length is shortened, the uniformity of mixing may be affected, resulting in unstable ignition and even ignition failure. Contents of the invention [0003] In view of this, the present invention proposes an ignition nozzle device with simple structure and stable ignition, which can improve ignition stability. [0004] The present invention proposes an ignition nozzle device capable of impr...
