Description

Technical Field

[0001] The present application belongs to the technical field of burners, and specifically relates to a secondary mixed combustion burner with continuous air input. Background Art

[0002] A burner is a device that converts substances into heat energy through a chemical reaction called combustion, that is, air and fuel are mixed in appropriate proportions through a premixing device to make them fully burn. A burner is a thermal energy device that delivers fuel and air into the furnace at the required concentration, speed, turbulence and mixing method, and enables the fuel to ignite and burn stably in the furnace. The fuel is mainly oil and gas. It is generally used in small and medium-sized oil or gas boilers.

[0003] The secondary mixed combustion burner is a highly efficient and low-pollution combustion technology that is widely used in industrial production and energy fields. It is a technology that feeds fuel and air from two different locations into the burner for mixed combustion, and is widely used in industrial production and energy fields.

[0004] However, the existing device is not equipped with a component for preventing dust from being filtered during the air input process. Since the dust contained in the air is not effectively filtered before entering the co-combustion component, dust particles are deposited and accumulated inside the device, forming ash and affecting the normal operation of the device.
