Description
Technical field
This utility model relates to a kind of three grades of program control burner nozzles of low NOx of flue gas recirculation.
Background technology
PM2.5 pollution problem at present has become China's many cities focus of attention such as Jing-jin-ji region, produces PM2.5
An important sources be that NO_x in Air Environment (NOx) discharges the secondary pollution that causes, NOx is at certain gas
In the case of marquis's condition such as humidity and temperature are suitable for, will be attached in the middle of the small dust of air and steam,
Define the diameter offspring again smaller than PM2.5 micron, thus have impact on the PM2.5 value in air, this
Plant after the offspring with harm chemical substance enters human body alveolar bigger to harm, therefore control
The discharge of nitrogen oxides (NOx) has become the key improving China's ambient air quality.
In order to control the nitrogen oxides harm to ecological environment of burner discharge, abroad from 50 years last century
In generation, rises and has begun to NO formation mechanism and the research of control method in combustion process.To the end of the seventies and
The eighties, the research and development of low NOx combusting technology reaches a climax, and have developed the realities such as low-NOx combustor
Use technology.Enter the nineties, again its low-NOx combustor developed has been done greatly about station boiler supplier
The improvement of amount and Optimization Work so that it is become better and approaching perfection day by day.
The existing gas heating boiler-burner theory of combustion is that air and combustion gas are defeated after certain proportion mixes
Deliver to combustor and carry out ignition, but due to air and the mixed proportion of combustion gas and discharge pressure, mixing
The factors such as time produce impact to burning, cause burning insufficient, add the discharge capacity of nitrogen oxides, reach
Less than real low nitrogen burning discharge standard, although inventing before inventor and applying for that disclosed patent reaches fall
The combustion efficiency of low NOx, " a kind of combustion gas classification as disclosed in number of patent application 201410506443.8
Burn ultralow nitrogen oxide burner ", but the burner of these patents can not meet and day by day improved at present
State environmental emissioning standard requirement.

In the present embodiment, air/fuel grading combustion technology: use secondary air combustion-supporting, three grades of segmentation combustions
The technology burnt, when designing gradual combustor nozzle 1, uses geometric simulation design, forms convolution burning,
And there is stratification, burner nozzle 1 angle of sprinkler design and gradient more conform to the needs that burn, and make combustion
Material and air segmenting mixed combustion, optimize burning deviation theory equivalent proportion, reduce the generation of NOx.
Recycle burning technology: utilize the secondary combustion-supporting wind refluxing opening 5 of combustion air and a combustion air refluxing opening
6, part combustion product gases is sucked back, enters burner, with air mixed combustion.Due to flue gas recirculation, combustion
The thermal capacity burning flue gas is big, and ignition temperature reduces.
Segmentation flame burning technology: natural gas is divided into multiple flammule, shape by unique novel nozzle arrangements
Becoming three grades of flare, three grades of oxygen supplys etc. are big due to flammule area of dissipation, and flame temperature is relatively low, makes " thermal response
NO " decline.Additionally, flame is little shortens the gas such as oxygen, the nitrogen time of staying in flame, to " heat
Reaction NO " and " fuel NO " have obvious inhibitory action thus reached NOx minimizing.
Wherein, three grades low nitrogen 4 are between two grades of stabilizers 8 are crisscross arranged, and two grades low nitrogen 2 are positioned at two
Level stabilizer 8 is crisscross arranged, and is between three grades low nitrogen 4 medial extremitys, and the low nitrogen of one-level 3 is then positioned at one
Arranging between level stabilizer 9 is interlaced, its passage is arranged at inside burner nozzle 1, secondary combustion-supporting
Wind refluxing opening 5 and a combustion air refluxing opening 6 can provide oxygen.
The beneficial effects of the utility model are:
