Example Embodiment

[0035] Example 1:

[0036] See Figure 1-4 , a swirl ultra-low NO X The gas burner comprises a burner shell 1, a primary air inlet part, a secondary air inlet part, a flue gas and air mixed air inlet part and an igniter 2, wherein the burner shell 1 has a cylindrical barrel structure, one end of which is a gas inlet and the other end is a gas outlet;

[0037] The primary gas inlet component comprises a primary gas pipeline 3 coaxially arranged with the combustor casing 1, a cyclone blade 4, a combustion-stabilizing baffle 5 and a primary gas nozzle 6 which are sequentially arranged on the primary gas pipeline 3 along the gas conveying direction, wherein one end of the primary gas pipeline 3 is provided with a primary gas inlet outside the combustor casing 1, and the other end is inserted into the combustor casing 1 from the gas inlet position. The number of the cyclone blades 4 and the combustion-stabilizing baffle plates 5 are multiple and are arranged obliquely along the outer si...

Abstract

The invention provides a rotational flow ultralow NOX gas burner. The rotational flow ultralow NOX gas burner comprises a burner shell, a primary gas inlet component, a flue gas and air mixed gas inlet component and an igniter; the burner shell is of a cylindrical barrel structure, one end of the burner shell is a gas inlet, and the other end of the burner shell is a gas outlet; the primary gas inlet component comprises a primary gas pipeline coaxial with the burner shell, cyclone blades, combustion stabilizing baffles and a primary gas nozzle, the cyclone blades, the combustion stabilizing baffles and the primary gas nozzle are sequentially arranged on the primary gas pipeline in the gas conveying direction, and the primary gas nozzle is arranged at the end of the inserting end of the primary gas pipeline, the primary gas nozzle is used for spraying primary gas into a gas boiler, and the multiple cyclone blades and the multiple combustion stabilizing baffles are annularly and obliquely arranged along the outer side wall of the inserting end of the primary gas pipeline. The rotational flow ultralow NOX gas burner is simple in structure and ingenious in design, the temperature of the local high-temperature position of flame in combustion can be effectively reduced, generation of NOX is effectively reduced, and therefore the emission amount of nitric oxide can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of combustion equipment, in particular to a cyclone ultra-low NO X gas burner. Background technique [0002] Nitrogen oxides are an important source of air pollution and one of the important factors that cause smog and acid rain. With the continuous improvement of environmental protection requirements and standards, the restrictions on nitrogen oxide emissions are becoming increasingly stringent. Natural gas burners use natural gas as fuel, and have been vigorously developed in recent years because of their clean, efficient and safe features. Reasonable design of the structure of the burner can make the natural gas and air mix evenly, and reduce the local high temperature on the basis of ensuring efficient combustion, thereby suppressing the formation of nitrogen oxides during the combustion process at the source and reducing the emission of nitrogen oxides. [0003] Most of the existing burners have the ...
