Embodiment 1

[0029] The invention discloses an environmentally friendly combustion ignition device with significantly reduced NOX, which is characterized in that: the gas supply of the ignition device is divided into two (or multiple) strands, and the primary air coefficient of one (or multiple) strands of gas is less than 1.0, that is, work in a rich combustion mode; the primary air coefficient of the other (or multiple) gas is greater than 1.0, that is, work in a light combustion mode, and the rich and light cross to achieve the purpose of low NOX emissions.

[0030] Arrange multiple gas supply nozzles around the air nozzle of the ignition device. The gas supply nozzles have a multi-level structure, and the rich and light combustion is carried out on a single layer of nozzles, that is, rich combustion is carried out on one layer of nozzles, while the other layer of nozzles Light burning is carried out on the upper side, so as to realize thick and thin burning.

[0031] Specifically, see ...

Abstract

The invention discloses a combustion ignition device and a combustion ignition method thereof. In the invention, gas supply of the combustion ignition device is divided into at least two parts: the device works in a dense combustion mode when the primary air coefficient of one part of gas is less than 1.0, and the device works in a dilute combustion mode when the primary air coefficient of the other part of gas is more than 1.0, thus realizing dense-dilute cross supply; a plurality of gas supply nozzles are arranged around the air nozzle of the ignition device, the gas supply nozzles are of a multi-layer structure, and dense / dilute combustion is integrated on a single nozzle layer; and dense combustion is carried out on one nozzle layer, and dilute combustion is carried out on the other nozzle layer, thus realizing dense-dilute combustion. By utilizing the combustion ignition device provided by the invention, NOX pollutants can be obviously reduced and the combustion efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of combustion control, and relates to a combustion ignition device, in particular to an environment-friendly combustion ignition device with significantly reduced NOx; at the same time, the invention also relates to a combustion ignition method of the combustion ignition device. Background technique [0002] The traditional ignition device adopts atmospheric combustion technology, its combustion temperature is high, and the high temperature zone of combustion occupies a large area of ​​the total combustion area. But there is a disadvantage during use: large NOX emissions. According to Zeldovich's thermal NOX generation theory, the amount of NOX generated is mainly related to the combustion temperature, and basically has an exponential relationship. total burnt area. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a combustion ignition device, w...
