Embodiment Construction

[0064] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the present disclosure will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0065] At present, 3D printing processing technology has become more mature and has been applied in engineering. However, due to the process requirements of 3D printing, a large number of support structures must be added inside the printed parts. These support structures will hinder the movement of airflow, increase flow loss, and increase airflow. Disturbance is not conducive to stable combustion. How to take into account the support problem during structural design and avoid adding additional support during 3D printing through optimized design is also a key issue.

[0066] This disclosure applies 3D printing technology to the structural design of the burner. During 3D printing processing, no additional support structur...

Abstract

The invention provides a combustor which comprises a first wall face, a second wall face, a third wall face, a first flow channel, a second flow channel, a third flow channel, a first air inlet pipe and a second air inlet pipe. The first flow channel is arranged between the first wall face and the second wall face; the second flow channel is arranged between the second wall face and the third wall face, and a third flow channel is arranged in the third wall face; the third wall face further comprises a first cavity used for stabilizing fluid in the third flow channel and a second cavity arranged below the first cavity and used for stabilizing fluid in the second flow channel; a partition plate is arranged between the first cavity and the second cavity; a rectifying column body is arranged in the second cavity, is arranged between the partition plate and the second wall face and is used for integrating fluid in the second cavity; and the first air inlet pipe and the second air inlet pipe both penetrate through the first wall face, the second wall face and the third wall face, an outlet of the first air inlet pipe is formed in the first cavity, and an outlet of the second air inlet pipe is formed in the second cavity.

Description

technical field [0001] The disclosure belongs to the technical field of combustion devices, and in particular relates to a burner. Background technique [0002] Gas turbines are widely used in electric power, aviation, petrochemical and other industries due to their small size and large output power. Due to energy crisis and environmental deterioration, there is an urgent need to develop high-efficiency and clean burners, which require reliable ignition, stable combustion, high efficiency and low emissions. [0003] Due to the current serious environmental pollution problems, clean combustion technology has emerged as the times require. However, although the related clean combustion technologies can effectively reduce the emission of pollutants, they all face the problem of unstable combustion and the size of the burner is relatively large. Contents of the invention [0004] In view of this, the present disclosure provides a burner in order to at least partly solve the a...
