Combustor and heat accumulating type combustion system thereof

Abstract

The invention discloses a combustor and a heat accumulating type combustion system thereof. The combustor comprises a combustor main body and a nozzle mechanism; the nozzle mechanism is arranged in ahollow cavity of the combustor main body, and the nozzle mechanism divides the combustor main body into a vestibular area and a secondary air mixed combustion area; a rotational flow channel and a direct flow channel horizontally penetrate through the nozzle mechanism, and the direct flow channel communicates the vestibular area with the secondary air mixed combustion area; the nozzle mechanism isfurther provided with an air-fuel gas mixing area and a primary air mixed combustion area, the rotational flow channel, the air-fuel gas mixing area and the primary air mixed combustion area are sequentially in communication with one another, and the primary air mixed combustion area is in communication with the secondary air mixed combustion area; the combustor main body is provided with a fuelgas channel which penetrates through the combustor main body to be in communication with the air-fuel gas mixing area so as to supply fuel gas; and an ignition gun for ignition is arranged in the primary air mixed combustion area. Air enters the air-fuel gas mixing area through turbulent flow of the rotational flow channel of the combustor to be fully mixed, and the NOx emission amount is greatlyreduced through sectional combustion.

Description

technical field [0001] The invention relates to the technical field of burners, in particular to a burner and a regenerative combustion system thereof. Background technique [0002] A burner is a general term for a device that makes fuel and air spray out and combust in a certain way. The industrial burner is a kind of burner, which is widely used in the industrial field. [0003] Industrial burners are commonly known as burners. There are many types and specifications, including fuel oil, gas (coal gas), and coal (powdered coal / coal-water slurry). [0004] Existing gas burners generally mix gas and air once, and then ignite and burn. When mixing in this way, there is insufficient mixing of gas and air, and it is often difficult to ensure the amount of air in the mixture. Excessive air will cause heat loss with the air, greatly reducing heat utilization and thermal efficiency; but insufficient air will lead to insufficient combustion of gas, resulting in a large amount of...

When this method is mixed, there is insufficient mixing of gas and air, and it is often difficult to ensure the amount of air in the mixture

Excessive air will cause heat to be lost with the air, and the heat utilization rate and thermal efficiency will be greatly reduced; but insufficient air will lead to insufficient combustion of gas, resulting in a large amount of carbon monoxide or residual gas, resulting in waste of energy, and there is a greater safety hazard Hidden danger
