Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0035] The embodiment of the present invention provides a nozzle. In the nozzle, the liquid fuel is formed into fine particles through the impact between the liquid fuel and the fixed wall surface and air-assisted atomization, which enhances the atomization effect and ensures the contact between the liquid fuel and the air. Mix well.

[0036] Specifically, the nozzle includes a nozzle, a liquid fuel injection part inserted in the nozzle ...

Abstract

The invention relates to the technical field of gas turbines, and discloses a nozzle and a combustion chamber. The nozzle comprises a spray pipe, a liquid fuel injection part inserted in the spray pipe and a liquid fuel blocking part; the spray pipe is provided with an air inlet, and air enters the spray pipe through the air inlet; and the liquid fuel injection part is used for injecting liquid fuel to the surface of the liquid fuel blocking part. According to the embodiment, the liquid fuel forms fine particles through the impact between the liquid fuel and a fixed wall surface and the air-assisted atomization, so that the atomization effect is enhanced, and sufficient mixing of the liquid fuel and the air is ensured.

Description

technical field [0001] The invention relates to the technical field of gas turbines, in particular to a nozzle and a combustion chamber. Background technique [0002] Gas turbine is a high-end energy equipment that converts the chemical energy of fuel into mechanical energy, electrical energy and thermal energy. It has the characteristics of high thermal efficiency, high power density, and low pollutant emission. It is widely used in distributed energy, combined heat and power, and aircraft tank power. and other fields. [0003] The combustion products of gas turbines and aero-engines contain NOx (nitrogen oxides). NOx mainly includes NO and NO2. Among them, NO is a colorless and odorless gas. If the concentration of NO in the atmosphere reaches a certain level, it will The combination of hemoglobin in the blood causes blood hypoxia and central nervous paralysis; NO2 is a red poisonous gas that can stimulate human respiratory organs and easily cause emphysema and lung cance...
