Description

Technical Field

[0001] This utility model relates to the field of burner nozzle technology, specifically a high-efficiency and energy-saving bell-type burner nozzle. Background Technology

[0002] The burner is one of the key components of a gasifier. Its main function is to introduce fuel and gasifying agent into the gasifier at a certain speed. Under the dynamic action of the high-speed injected gasifying agent, the fuel and gasifying agent are fully mixed, resulting in an incomplete combustion chemical reaction. Since the operating temperature inside the gasifier is usually above 1400℃ and under pressure, the requirements for the burner are very high. If the burner structure is not properly designed, it will lead to poor mixing of fuel and gasifying agent, insufficient cooling of the burner tip, and excessive thermal stress, which may seriously affect the normal operation of the gasifier.

[0003] Chinese patent document CN202021109U discloses a gasifier burner, belonging to the field of gasifiers. The gasifier burner of this utility model includes a burner body (1), which has a cooling water channel (6). A front face (3) is provided at the front end of the burner body (1), sealing the cooling water channel (6). A baffle (2) is provided within the cooling water channel (6) at the front end of the burner body (1), forming a multi-swirling or single-swirling water-cooling channel between the inner side of the front face (3) and the baffle. The gasifier burner of this utility model has a simple structure, making manufacturing, installation, and maintenance more convenient and faster; the front face significantly reduces cooling water disturbance, resulting in good cooling effect, making it suitable for widespread application.
